- Another weird Tomcat problemI'm getting the following exception when I call "HttpSession session =
request.getSession(true)":
java.lang.NoClassDefFoundError:
org/apache/coyote/tomcat4/CoyoteRequest$PrivilegedGetSession
Again, I think it has something to do with the security manager; it is
a problem that just cropped up when I uploaded new class files to the
Tomcat server. A server restasrt didn't cure the problem.
Any ideas?
Thanks!

- Creating ANT task which invokes target with dynamic propertiesI want to create an Ant task which loops through subdirectories and
then calls an Ant target ?this is easy enough through the
project.executeTarget method. But I want to pass the subdirectory
name as a property to the "called" target. This I do through the
project.setProperty method. Yet the target only has the original
value of the property and not the modified value. I am assuming that
this is because once a target and its tasks are loaded, the properties
are then fixed ?immutable.
So my strategy is to "refresh" the target before my task executes the
target. I was thinking to create a new target, do a shallow copy of
info, copy to the project and then execute the new target. Thoughts?
Other ideas?
Here is the sample ANT build code:
<target name="build" >
<IterateDirectoryTask RootDirectory="."
ExecuteTarget="TestTarget"/>
</target>
<target name="TestTarget" >
<echo message="Hello from TestTarget" />
<echo message=" subdirectory = ${subdirectory}" />
</target>
And here is the TASK:
public class IterateDirectoryTask extends Task {
private String _rootDirectory;
private String _executeTargetName;
public void setRootDirectory(String aDirectoryName) {
_rootDirectory = aDirectoryName;
}
public void setExecuteTarget(String aTargetName) {
_executeTargetName = aTargetName;
}
public void execute() throws BuildException {
if (_executeTargetName == null) {
throw new BuildException("ExecuteTarget must be
specified");
}
File lRootDirectory = new File(_rootDirectory);
if (!lRootDirectory.isDirectory()) {
throw new BuildException("'"+_rootDirectory+"' is
not a directory");
}
File[] lFiles = lRootDirectory.listFiles();
for (int i=0; i < lFiles.length; i++) {
if (lFiles[i].isDirectory()) {
project.setProperty("subdirectory",
lFiles[i].getName());
Target lTarget =
(Target)project.getTargets().get(_executeTargetName);
project.executeTarget(_executeTargetName);
}
}
}

- ImageUpdate and threadsHi !!!
I have a technical question about the loading of images. I have used for
long time the SwingWorker class for loading images (as the SUn
examples), however, in some books I have found that it is possible to
use the ImageUpdate methods for asynchronous loading.
Which one is better? The graphical thread made by SwingWorker or the
Image class methods?
thanks a lot for your help,
Marcelo

- Simple Date Format - milliseconds with more precisionI'm using a UDB database, where the timestamp of a Date field returns
me dates with milliseconds up to 6 decimals:
2005-02-25 11:50:11.579411
I'm looking for two possible ways to deal with time stamp.
1. I've tried creating a Simple Date Format object with this time
stamp, but I don't know how to save the milliseconds with all 6 digits.
I can store up to 3 ("SSS"), but no more than that
Tried:
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd
HH:mm:ss.SSSSSS");
but that causes havoc.
2. Write a query that'll truncate the time stamp and lop off the final
3 digits. This query would need to be basic enough to work in MSSQL,
Oracle, and UDB without any modifications.
Any ideas?

- a great dealIT'S SIMPLE AND IT'S LEGAL!!!!!!! I found this on a bulletin board
and decided to try it a little while back; I was browsing through
news groups just as you are right now and came across an article
similar to this saying that you could make thousands of dollars
within weeks with only an initial investment of $6.00!! So, I thought
yeah right. This must be a scam, but like most of us, I as curious,
so I kept reading. Anyway, it said that you send one dollar to each
of the six names and addresses stated in the article. You then delete
the first address and change the numbers. (2 becomes 1, 3 becomes 2,
etc.) Place your own name and address on the bottom of the list at
number 6 and post the article to at least 200 newsgroups. (There are
thousands) No catch that was it. Therefore, after talking to a few
people and thinking it over I decided to try it. What do I have to
lose except 6 stamps and $6.00 right? Then I invested the measly six
dollars. WELL GUESS WHAT!!! Within 7 days, I started getting money in
the mail!!! I was shocked. I though it was going to stop but it just
kept coming. In my first week, I made $25.00. By the end of the
second week, I had $900.00. In the third week, I made $5,000.00!!!
It's still growing right now. This is my fourth week and I have made
a total of just over $38,000.00! Moreover, it's still coming in
rapidly. This is certainly worth $6.00 and 6 stamps. I have spent
more then that on the lottery!! Let me tell you how this works and
most importantly why it works... Also make sure that you print a copy
of this article NOW so you can get the information off of it, as you
need it. I promise you that if you follow the directions exactly,
that you will start making more money than you possibly thought just
by doing something so easy!! SUGGESTION: READ THIS ENTIRE MESSAGE
CAREFULLY (Print it out or download it) Follow the simple directions
and watch the money come in! It's easy. It's legal. And your
investment is only $6.00 (plus postage) IMPORTANT: This is not a rip
off; it is not indecent; it is not illegal; and it is virtually no
risk - it really works!!!!! If all of the following instructions are
adhered to, you will receive extraordinary dividends. PLEASE NOTE:
please follow these directions exactly and $50,000 or more can be
yours in 20-60 days. This program remains successful because of the
honesty and integrity of the participants. Please continue its
success by carefully adhering to the instructions. You will now
become a part of the mail order business. In this business, your
product it not solid and tangible, it's a service. You are in the
business of developing a mailing list. Many large corporations are
happy to pay big bucks for quality list. However, the money made from
the mailing list is secondary to the income, which is made from
people like you and me asking to be included to that list. Here are
the four steps to success: STEP 1: Get 6 separate sheets of paper
write the following on each piece of paper "PLEASE PUT ME ON YOUR
MAILING LIST." Now get 6 US 1 dollar bills and place ONE inside EACH
of the six pieces of paper so the bill will not be seen through the
envelope to prevent thievery. Next, place one paper in each of the
six envelopes and seal them. MAKE SURE THERE ARE ENOUGH STAMPS ON
YOUR ENVELOPES. You should now have 6 sealed envelopes, each with a
piece of paper stating the above phrase your name and address and a
$1.00 bill. What you are doing is creating a service. THIS IS
ABSOLUTELY LEGAL! You are requesting a legitimate service and you are
paying for it! Like most of us, I was a little skeptical and a little
worried about the legal aspects of it all. So, I checked it out with
the U.S. Post Office (1-800-725-2161) and they confirmed that it is
indeed legal!!!!! Mail the six envelopes to the following addresses
.
#1) Rupert Springsteen 2103 E. Pine St. Tucson, AZ 85706
#2) Mark Finch 4909 S. Cherry Ave. Tucson, AZ 85706
#3) Joanty Gomez 6131 South Meade Ave. Chicago, IL 60638
#4) Kasey Nicoletti 127 cherry lane Medford, NY 11763
#5) Alexis Beadles 22310 Audrey, Warren Mi, 48091
#6) Shane MacDonald 502-43 Powell St., Vancouver, BC , Canada, V6A 1E9
STEP 2: Now take the #1 name off the list that you see above, move
the other names up (6 becomes 5, 5 becomes 4, etc...) and add YOUR name
as number 6 on the list. STEP 3: Change anything you need to but try
to keep this article as original as possible. Now post your amended
article to at least 200 news groups. (I think there are 24,000
groups) All you need is 200, but remember, the more you post, the
more money you make!! ** EVERYBODY AROUND THE WORLD CAN DO THIS BUT
REMEMBER TO PUT ENOUGH STAMPS ON YOUR ENVELOPES!!!! ** This is
perfectly legal! If you have any doubts, refer to title 18 sec. 1302
& 1341 of the postal lottery laws. Keep a copy of these steps for
your self and whenever you need money, you can use it again and
again. PLEASE REMEMBER that this program remains successful because
of the honesty and integrity of the participants and by carefully
adhering to the directions. Look at it this way, if you are of
integrity, the program will continue and the money that so many
others have received will come your way. NOTE: You may want to retain
every name and address sent to you, on either a computer or a hard
copy and keeps the notes people sent you. This verifies that you are
truly providing a service. (Remember to wrap the $1 bill in the note
to prevent mail theft.) So, as each post is downloaded and the
directions carefully followed, six members will be reimbursed for
their participation as a list developed with one dollar each. Your
name will move up the list geometrically so that when your name
reaches the #1 spot you will be receiving thousands of dollars in
CASH!!!! What an opportunity for only $6.00 ($1 for each of the 6
people listed above) Send it now, add your own name to the list and
you're in business! DIRECTIONS: HOW TO POST TO NEWS GROUPS STEP 1:
You do not need to retype this entire letter to do your own posting.
Simply put your cursor at the beginning of this letter and drag your
cursor to the bottom of this document, and select "copy" from the
edit menu. This will copy the entire letter into the computers
memory. STEP 2: Open a blank notepad file and place your cursor at
the top of the blank page. From the edit menu, select "paste". This
will paste the copy of the letter into the notepad so you can add
your name to the list. STEP 3: Save your new notepad file as a .txt
file. If you want to do your own postings in different settings,
you'll always have this file to come back to. STEP 4: Use Netscape
and Internet Explorer and try searching for various news groups (on-
line forums, message boards, chat sites, discussions.) STEP 5: Visit
these message boards and post this article as a new message by
highlighting the text of this letter and selecting "paste"from the
edit menu. Fill in the subject, this will be the header that everyone
sees as they scroll through the list of postings in a particular
group, click the post message button. You're done with the first one!
CONGRATULATIONS... THAT'S IT! All you have to do is jump to different
news groups and post away, after you get the hang of it, it will take
30 seconds for each news group! **REMEMBER THE MORE NEWSGROUPS YOU
POST IN (MESSAGE BOARDS, ETC...) THE MORE MONEY YOU WILL MAKE!! BUT YOU
HAVE TO POST A MINIMUM OF 200. That's it! You will begin receiving
money from around the world within days. You may want to eventually
rent a P.O. Box due to the large amount of mail you will receive. If
you wish to stay anonymous, you can invent a name to use as long as
the postman will deliver it. **JUST MAKE SURE THE ADDRESS IS
CORRECT** Let me break it down, say I receive only 5 replies, so then
I made $5 with my name it number 6 on the letter. Now each of the 5
persons who just sent me $1 made the MINIMUM 200 postings, each with
my name at #5 and only 5 people respond to the original 5 people.
That is another $25 for me. Now those 25 people make the MINIMUM 200
post with my name at #4 and only 5 replies each, I will make $125.
Now, those 125 people post the MINIMUM 200 postings with my name at
#3 and only get 5 replies each, I will make an additional $625! O.k.,
now here's the fun part each of those 625 people post a MINIMUM 200
with my name at #2 and they only get 5 replies they just made me
$3,125!!! Those 3125 people send a MINIMUM 200 posting and they only
get 5 replies each with my name at #1, I will receive $15,625!!! With
an original investment of $6!!! AMAZING!!!! . When your name is no
longer on the list, you just take the latest postings in the news
groups and send out another $6 to names on the list putting yourself
at #6 and start posting again. Thousands of people are joining the
Internet each day and they are reading articles like these just as
you are right now. So this can never be played out just keep it going
and you can make tons of money to!!!! Please try it now and make big
bucks in a few short weeks!!!!!!

- Tomcat and Connection pool size difficultiesI am experiencing something similar. I manage a website that is load
balanced across two servers. They are both running Tomcat 5 and they
both connect to the same database. On both servers we have maxActive
set to 10 and maxIdle set to 2 in the Tomcat ResourceParams. For the
most part, Tomcat DBCP plays by the rules and keeps the number of
connections to our database below 10, but today for reasons unknown,
both servers started using around 50 connections. Our database
quickly ran out of connections and our website produced errors.
I would have blown this off as a glitch, but both Tomcat servers
exhibited this behavior independently of each other, which means that
something triggered this behavior in a reproducable way. Anyone else
having this problem? Anyone find a solution?

- Property Editor Hi all,
I am doing a library with some beans (Bean A and B for example). B has a
"aProperty" that references an object of type A. I would like to do a
property editor thar pemits, doing an object of type B to get in the
aProperty a list of A existing objects. For example, y put in my form 2
objects a1 y a2 of type A. if I create a b1 object of type B y would like to
show a1 and a2 in the posibles values.
I can do a static list using the getTags function of my property class,
but don't know how to access to a1 and a2 variables.
Any idea ?
Thanks a lot,
Sylvain.

- .Net winforms not that greatFrustrated with java desktop deployment issues , I decided to give .net
a try. I must
say that I don't find the winforms very elegant. at first glance it
seems snappy and look and feel on windows seems right without really
any effort. but beyond that It is very difficult to extend and somehow
it seems like programming in VB.It does not have the coherence of swing
or swt. I guess i am back from that detour. I going to give swt/GCJ a
try this time. I had tried it before and was having a hard time getting
executables with swt. and all of this to get around forcing the user to
download the jre for desktop apps....

- Strange problemDear All:
I have used MySQL as prototype on an application that I am developing.
The project has been
approved and I am now moving to Oracle for the production run. I have a
section
that deals with user password. My front end is in JSP/Servlet using
Apache tomcat and talking
to Oracle 8i using JDBC driver from Oracle (but I am using the Oracle 9i
driver).
The user password, I am using MD5 hashes and storing the string copy of
that hashes onto the database (as varchar).
MySQL was ok. However, when I moved the application to talk to Oracle,
I am always getting a different string back
from the database than what I am saving into it. However, I am
always getting back, from ORacle, the same
set of characters. So it was consistently different but consistently in
the same format. So I think there
are some character conversion that is happening. Some of the
characters are non-printable characters so
they look like rubbish. But you can still compare with your bare eyes
as the strings always contain the
same set of characters.
I think I am missing something as to how Oracle handle non-printable
character strings.
Any help much appreciated!!
Please email me as well as posting back to the newsgroup.
Thanks

- Which scripting language for renaming directories/files etcI have a directory sructure with many many subdirectoies many of which
contain various files. These directories/sub directories/ files may
contain a variable ie MYNAME that I want to substitute for a value ie
DAVID.
For Example I might want to turn the following...
c:\blah\blahMYNAMEblah\blahMYNAME\MYNAME.txt
c:\blah\blahMYNAMEblah\blahMYNAME\aaaMYNAME.txt
c:\blah\blahMYNAMEblah\MYNAME\MYNAME.dat
...into...
c:\blah\blahDAVIDblah\blahDAVID\DAVID.txt
c:\blah\blahDAVIDblah\blahDAVID\aaaMDAVID.txt
c:\blah\blahDAVIDblah\DAVID\DAVID.dat
...I was using ANT, but it seems to lack the ability (or I lack the
knowledge) to rename whole directory structures in this way without me
naming each and every one in the script, and since the actual directory
structure is much bigger and subject to change I dont really want to do
this!
Additionally I need to replace the content within a file. ie if
MYNAME.dat had this content...
"Hello, my name is MYNAME"
...then I want to replace it with...
"Hello, my name is DAVID"
...so my question is, what scripting language would be most suitable
for this type of problem?
Thanks

java-programmer, Interrupt blocked database query
Hello all,
I know this has been discussed often, but I still can not find a good
solution. I want to write an application where in one thread a database
query is run against an oracle db. This query could run into a deadlock
so I have to monitor this in another thread and react accordingly.
I understand that the use of Thread.stop() is strongly discouraged and
not working either. What is the best solution to this? Could I close the
socket and see what is left from the database connection? Where do I get
the socket then? Any other ideas?
Thanks,
Markus

If an SQL query causes deadlock then that should send up big red flags.
Fix the problem at its source instead of looking for a workaround.

You probably don't mean deadlock, at least a simple DBMS deadlock. The
DBMS knows it before you do , and will kill one of your transactions.
If you just mean 'blocked', Java provides the Statement.cancel() call.

Right.

> Joe Weinstein at BEA Systems
That sounds like worth trying. I could save the current executing
Statement in a public variable and call the cancel() method from the
monitor thread.

That's alwas a good advice :-)
The problem for me is, due to a poorly designed app, I can't even see
the reason. I'm about to change that.

BUY DISCOUNT Drugs: A Shopping Guide for online shoppers - This site
has the ambition to be the best online Drugs discount shops guide
totally independent from any pharmacy store. We work hard to get the
best possible discount Drugs information, and deals for online Drugs
buyers. Compare prices of discount Drugs at over 50 online discount
pharmacy retailers. Also, get information about manufacturers'
coupons, other pharmacies products, online shoppers' rights, taxes,
and more.
BENEFITS OF ONLINE PHARMACIES
Lower prices -- Lower drug prices in other countries and lower
overhead
costs compared to bricks and mortar pharmacies often result in
savings
compared to local pharmacy prices. In addition, you can quickly shop
around for the best price online.
Privacy/Anonymity -- You may feel more comfortable purchasing or
asking
questions online (or by fax or phone) regarding certain medications.
However, privacy can be compromised if an online pharmacy is using
your information for other purposes so it is important that the
online
pharmacy has an appropriate privacy policy and upholds it; this is
one
of the things that 1PharamcyGuide.com checks for you and provides in
its Pharmacy Profiles.
Access to more generics -- Due to differences in patent protection,
generic drugs may be available outside the U.S. for drugs only sold
as
brand name versions in the U.S.
Prescription not needed -- Some sites do not require you to have a
prescription at all to order medications -- although this is not
always
wise or legal. Other sites offer to write a prescription for you
based
on an online consultation. In many states this practice is illegal
and
the American Medical Association considers the practice unethical.
Convenience -- If you find it physically difficult to make it to the
pharmacy, live in remote rural areas, or have a very busy schedule,
online and mail-order pharmacies enable you to avoid travel and can
save you time.
Medical information -- Some online pharmacies provide useful
information about medications and diseases as well as links to
medical
resources such as universities, government agencies, and health
associations.

1. put the requesting site in IE to local-network
2. in the IE extended security option enable Integrated Windows
Authentication
then you should see a client response something like YIll....... which is
true.
(nope i get
TlRMTVNTUAABAAAAB7IIogoACgAuAAAABgAGACgAAAAFASgKAAAAD0ZJTElQTUNSRURPQkFOS0E=
which is NTLM)
To configure Intranet Authentication:
1. Click the Security tab, click Local intranet, and then click Custom
Level.
2. In the Security Settings dialog box, scroll down to the User
Authentication section of the list.
3. Select Automatic logon only in Intranet zone. This setting prevents users
from having to re-enter logon credentials; a key piece to this solution.
4. Click OK to close the Security Settings dialog box.
In addition to the previous settings, one additional setting is required if
you are running Internet Explorer 6.0.
1. In Internet Explorer, click Tools, and then click Internet Options.
2. Click the Advanced tab.
3. Scroll down to the Security section.
4. Make sure that Enable Integrated Windows Authentication (requires
restart) is checked, and then click OK.
5. If this box was not checked, restart the browser.
I do have JCIFS NTLM setup for entering the site, but afterwards i need to
do authorisation with Kerberos to authenticate with EIM to work with jt400
on as400.
So when i do
httpServletResponse.setHeader("WWW-Authenticate", "Negotiate");
i allways get the NTLM token.
Searched the web couldn't find anything apart from the above given steps.

- JSF tld newbie QuestionHello all,
I was looking at the JSF implementation source and some sample JSPs
from sun. I was wondering how/where the tld files are referenced/found.
For example the tld file html_basic.tld is jarred in the jsf-impl.jar.
In a jsf page it is imported with <%@ taglib prefix="h"
uri="http://java.sun.com/jsf/html" %>. Now there does not seem to be
any reference to the uri mapping in the web.xml or faces-config.xml or
anywhere else to the above uri.
So how does the application know that uri="http://java.sun.com/jsf/html"
references html_basic.tld?
Thanks

- mysql and named pipesI'm using Win2000 and I want to use named pipes instead of a TCP/IP
connection to MySql.
I'm using the following connection string:
jdbc:mysql://localhost/?enable-named-
pipe&socket=MySQL&socketFactory=com.mysql.jdbc.NamedPipeSocketFactory
And I get the following error:
java.io.FileNotFoundException: \\.\pipe\MySQL (The system cannot find the
file specified)
Any idea what I'm doing wrong?

- Generating classes for tables of a data baseHi,
I've got an already existing data base (Postgres) which consists of a
couple of tables and connections. There exist also some stored
procedures. Now, how can I get java-classes generated of this
information? Which tool can do this?
I would like to see a class for each table and methods to call stored
procedures or to locate records by their key.
PS. this must be done for c++, too.

- Synchronized output stream sends data out of order, Possible?Hi All,
I have a strange problem... I have > 1000 threads wanting to send data
through synchronized DataOutputStream wrapped around a sockets
OutputStream. Replies sent across the internet are received perfectly
in the sent order but across the router the stream is somehow
corrupted.
Is there something I need to set to stop this problem?
Please take a look a the code and corrupted output to see if I'm just
being a bit dumb... thanks
to send:
try {
synchronized(dos) {
System.out.println(getName() + " send response " + file + "
resp " + resp);
dos.writeUTF(file);
dos.writeByte(resp);
dos.flush();
}
} catch (Exception e) {
System.out.println(file + " response failed lm");
e.printStackTrace();
}
I checked to see that syncronisation was being obeyed, no other thread
accesses the stream until it's released by another so all bytes are
written to the stream in the desired order.
to receive:
try {
pause(); //synchronize on this and wait until is.dataAvailable()>0
String file = is.readUTF();
System.out.println("rec reply " + file + " rm");
while (!"done".equals(file)) { //done respone sent when all reply
threads terminate
pause();
int reply = is.readByte();
System.out.println("resp " + reply + "rm");
pause();
file = is.readUTF();
System.out.println("rec reply " + file + " rm");
}
System.out.println("done received rm");
} catch (Exception e) {
e.printStackTrace();
}

You'll see below that after 0008_01.dat and reponse as 4 is sent
0012_02_1.dat is next received but wasn't sent until much further down
the list. This corrupts the stream, which then appears to be in the
correct order there onwards. Following output is all read in as the
result of a single readUTF() operation

In this code, you discard 3 of your 4 constructor parameters. I am
begriming to wonder if you imagine java automatically copies
constructor parameters to the matching instance variables.
You code offers no way to set the public instance variables, unless
you count aCpu.name = "Sempron";

- #gN Almost FREE MONEY !! #gNMAKE MONEY!!!
MAKE THOUSANDS!!!
I found this on a bulletin board and decided to try it: I don't care about
the useless pre-fabricated crap this message usually says. All I say is, it
works. Continue pre-fab crap.
WELL GUESS WHAT!!!
Within seven days, I started getting money in the mail!! I
was shocked!! I figured it would end soon, but the money just kept
coming in. In my first week, I made about $25.00. By the end of the second
week I had made a total of more than $1000.00!!
Let me tell you how this works and most important, why it works..........
also make sure you print this out NOW, so you can get the information off
of it, as you will need it. I promise you that if you follow the directions
exactly that you will start making more money than you thought possible by
doing something
so easy!!
Suggestion: Read this entire message carefully!! (Print it out or download
it)
Follow the simple directions and watch the money come in!! It's easy.
It's legal. And, your investment is only $6.00 (Plus postage) !!!
You can use any currancy as people can always change it..
IMPORTANT:
This is not a rip-off, it is decent; it's legal; and it is virtually no
risk - it really works!! If all the following instructions are adhered to,
you will receive extraordinary dividends.
PLEASE NOTE:
Please follow the directions EXACTLY, and $50,000 or more can be yours
in 20 to 60 days. This program remains successful because of the honesty
and integrity of the participants. Please continue its success by carefully
adhering to the instructions. You will now become apart of the Mail Order
business.
You are in the business of developing Mailing Lists. Many large corporations
are happy to pay big bucks for quality lists. However, the money made from
the
mailing lists is secondary to income which is made from people like you
and me asking to be included in that list. Here are the four easy steps to
success.
STEP ONE:
Get six separate pieces of paper and write the following on
each piece of paper "PLEASE PUT ME ON YOUR MAILING LIST."
Now get 6 U.S. $1.00 bills and place ONE inside of EACH of the six pieces
of paper so the bill will not be seen through the envelope (to prevent
thievery). Next, place one paper in each of the six envelopes and seal them.
You now should have six sealed envelopes, each with a piece of paper stating
the above phrase, your name and address, and a $1.00 bill. What you are
doing is creating a service.
THIS IS ABSOLUTELY LEGAL!!!!!
You are requesting a legitimate service and you are paying for it!! Like
most of us I was a little skeptical and little worried about the legal
aspects of it all. So I checked it out with the U.S. Post Office
(1-800-238-5355)
and they confirmed that it is indeed legal!!
Mail the six envelopes to the following addresses:
Matthew Dutton
46 Hayworth St
Point Vernon, Hervey Bay
QLD, 4390
Australia
R. Visser
P.O. Box 274
Nobby Beach
QLD, 4218
Australia
S. Phillips
77 Manly Drive
Robina, QLD 4226
Australia
Chris Pittman
7651 Abigail Glen Dr.
Charlotte, NC 28212
USA
Mike Vango
29 Pebblewood Ave
Scarborough, ON M1V-2A7
Canada
C. Wehler
137 Sara Rd
St. Marys, PA 15857
USA
STEP TWO:Now take the #1 name off the list that you see above, move the
other names up (six becomes 5, 5 becomes 4, and etc.) and add YOUR NAME as
number 6 on the list.
STEP THREE:
Change anything you need to but try to keep this article as close to
original as possible. Now post your amended article to at least 200 news
groups. : (I think there are close to 24,000 groups) All you need is 200,
but
remember, the more you post, the more money you make!! This is perfectly
legal!! If you have any doubts, refer to Title 18 Sec. 1302 & 1341 of the
Postal Lottery laws. Keep a copy of these steps for yourself and whenever
you need money, you can use it again, and again. PLEASE REMEMBER that this
program remains successful because of the honesty and integrity of the
participants and by their carefully adhering to directions. Look at it this
way. If you were of integrity, the program will continue and the money that
so many others have received will come your way.
NOTE: You may want to retain every name and address sent to you,> either on
a computer or hard copy and keep the notes people send you.
This VERIFIES that you are truly providing a service. (Also, it might be
a good idea to wrap the $1 bill in dark paper to reduce the risk of mail
theft). So, as each post is downloaded and the directions carefully
followed, all members will be reimbursed for their participation as a List
Developer with one dollar each. Your name will move up the list
geometrically so that when your name reaches the #1 position you will be
receiving thousands of dollars in CASH!!! What an opportunity for only $6.00
( $1.00 for each of the first six people listed above) Send it now, add your
own name to the list and you're in business!!!
*****DIRECTIONS FOR HOW TO POST TO NEWS GROUPS!!!*****
STEP ONE: You do not need to re-type this entire letter to do your own
posting. Simply put your cursor at the beginning of this letter and drag
your cursor to the bottom of this document, and select 'copy' from the edit
menu. This will copy the entire letter into the computer's memory.
STEP TWO:
Open a blank 'notepad' file and place your cursor at the top
of the blank page. From the 'edit' menu select 'paste'. This will paste a
copy of the letter into the notepad so that you will add your name to the
list.
STEP THREE:
Save your new notepad file as a text file. If you want to do your posting
in different settings, you'll always have this file to go back to.
STEP FOUR:
You can use a program like "postXpert" to post to all the newsgroups at
once. You can find this program at <<http://www.download.com>>.
Use Netscape or Internet Explorer and try searching for various new
groups (on- line forums, message boards, chat sites, discussions.)
STEP FIVE:
Visit message boards and post this article as a new message by
highlighting the text of this letter and selecting paste from the edit menu.
Fill in the subject, this will be the header that everyone sees as they
scroll through the list of postings in a particular group, click the post
message button. You're done.
Congratulations!!!!!!
THAT'S IT!! All you have to do, and It Really works!!!
BEST WISHES ...

- Making new Flavors : Making a custom transferhandler for and drop applicationsHi all .. im trying to make a simple application thru which i can
