- Interrupt blocked database queryHello 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

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";

- SPNEGO TOKENHello,
trying to implement some kerberos authentification, and all works fine if
authenticating local user, but when i try to authenticate
remote user with servlet, through Internet Explorer i keep getting the NTLM
token not the SPNEGO.
I have done following things:
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.

- www/mod_jk2 fails to build (Maintainer fix enclosed!)
>Submitter-Id: current-users

>Confidential: no
>Synopsis: www/mod_jk2 fails to build (Maintainer fix enclosed!)
>Severity: non-critical

System: FreeBSD fuzzilicious.fuzzynerd.com 5.0-CURRENT FreeBSD 5.0-CURRENT #0: Tue Apr 1 11:50:43 EST 2003 email***@***.com:/usr/obj/usr/src/sys/FUZZILICIOUS i386
>Description:
Attempting to build mod_jk2 yields the following:
libtool: link: `../common/jk_ajp12_worker.lo' is not a valid libtool object
>How-To-Repeat:
I could not reproduce this bug on 5.x, I received one report from
someone who did. I wasn't aware of the problem until I started
receiving bug reports from people running 4.7 and 4.8. If you attempt
to build mod_jk2 on 4.x, you should be able to repeat this bug 100% of
the time.
>Fix:
I found a one-line fix that seems to eliminate this problem for me.
Thanks go to the apache folks, who rolled this into one of the later
mod_jk versions. I'll update the port to the latest version in the
near future. Until then, please commit this fix.
Fix: replace the contents of www/mod_jk2/files/patch-configure.in with
the following:

- 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

- 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.

- EL: escaping HTMLHi!
I need to escape HTML - can this be done with EL alone? For a matter of
quotations marks I cannot use JSTL in a plain JSP:
<a href="javascript:f('<c:out value="problem"/>')">

- 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:

pipe&socket=MySQL&socketFactory=com.mysql.jdbc.NamedPipeSocketFactory
And I get the following error:

Any idea what I'm doing wrong?

- #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 ...

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.

- question about console InputHello group,
I wonder if there's any equivalent to C's getch() in java, i.e to

without pressing the "Enter" key.
Any solution or suggestion is welcome, thank you!

- 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();
}

0012_02_1.dat is next received but wasn't sent until much further down

- Problems with NetBeans and Subersion.Hi all,
I've got a problem with the subversion module.
I started to checkout from a svn repository with Subversion-
>Checkout...
Next I was asked to create a new project. I took a C++ project (C++
module).
My project window showed a new project BUT with ZERO files! But the
svn repository is fine...
Any hints for me?
Thanks

- A simple way to play a file in an ApplicationHi all,
I am looking for a simple way to play a sound clip (.au file) in a java
application (not applet). AudioClip in java.applet seems to require URLs for
clips, and the Java Sound API looks a little too elaborate for what I am
trying to do. All I need is for this .au file to be played once inside
another method. Can anyone give me some pointers here?
TIA

- Adding Fractions ProblemI can use the code below to add fractions together through adding instances
of the class Rational together, but my code to reduce the result to its
lowest terms has no effect. Why is this?
public class Rational
{
// instance variables - replace the example below with your own
private int numerator;
private int denominator;
public Rational()
{
}
public Rational(int num, int denom)
{
numerator = num;
denominator = denom;
}
public int getNumerator()
{
return numerator;
}
public int getDenominator()
{
return denominator;
}
public Rational add(Rational rhs)
{
int numerator1 = (rhs.getDenominator() * numerator);
int newDenom = (rhs.getDenominator() * denominator);
int numerator2 = (denominator * rhs.getNumerator());
int newNum = (numerator1 + numerator2);
if((newDenom % newNum) == 0)
{
// This code is supposed to reduce the result to its lowest
terms
int commonFactor = (newDenom / newNum);
newDenom /= commonFactor;
newNum /= commonFactor;
}
return new Rational(newNum, newDenom);
}
}

- How to delete lines from input file?I'm writing this program to implement a two phase multi-way merge sort.
It works by splitting the data to be sorted into temporary sorted
lists (output files) equal in size to a memory constraint that is
passed in when the program is run. What I've got to do now is actually
merge the lists into one final output. The trick is that this is
supposed to save disk I/Os. What happens is I read the smallest
element from each temporary file into an array. From that array, the
smallest goes into the final output, and that element is then replaced
by the next element from the same list.
I feel like what I need to do is delete a number from one of the
temporary when it's read into the array. Then all I have to do is read
the first line from the same list to get the next number into the
merging array. Any suggestions on how to do this?
I'm using SDK 1.4.2 and the input/output files are binary, so I'm using
DataInput/OutputStream to do this.
Thanks,

- Specify security access in JNLPIs it possible to specify what access the web start application needs to
run?
Using the JNLP code
<security>
<all-permissions/>
</security>
All access can be gained, but I would like to restrict it to contacting
certain servers and clipbaord access. More like 'java.awt.AWTPermission
"accessClipboard"'. Is it possible to use this policy code in the JNLP file?

- How do you do THAT with genericsI am working on an event mechanism. Part of my need is to be able to
have a pool of events that can be reused, rather than incurring the cost
of instantiating one via reflection every time I need one. The pool
interface has this method for checking out an event:
<E extends Object & Event> E checkout(Class<E> cl);
Creating an event from this is easy; "return cl.newInstance();" works
fine. The problem is in storing them for later use.
Since there are many event classes in the event hierarchy, and since I
want this method to be able to return an event of the exact type (so I
don't have to cast it after getting it), I thought to use an inner class
(PoolList<E extends Event>) that holds a list of just one type of Event
and tracks which of its objects are in use and which are available. Then
I could use a Map to key these PoolList objects by Class.
That map is the problem. I need to have it store Class<E> as keys and
PoolList<E> as values...the same parameter (E) in both. Except that the
parameter isn't fixed...it could be any implementation of Event. So the
closest thing that I have is...
private Map<Class<? extends Event>, PoolList<? extends Event>> pool;
...which is wrong because it can't guarantee that the type parameters to
Class and to PoolList are the same (only that they are both
implementations of Event, but they could very well be different ones).
Something like...
private <T extends Event> Map<Class<T>, PoolList<T>> pool;
...would work, except that it isn't legal (the <T extends Event> part
can't be used for fields, only for generic methods). It makes sense that
there should be SOME way to do it...all of the necessary type
information is there at compile time and nothing that's needed at
runtime gets erased. But I can't come up with it.
All I need is a Map that knows that if one type parameter is being used
in the key, the same one should be used in the value. Is there a way in
generics to do this?

- Java Swing Certified?I'm a Java Certified programmer (310-035) and currently I'm working
with Swing GUI components in my job.
I would like to ask if anybody knows if there's any certification exam
for Swing-AWT. I know this topic was removed from the programmers exam,
but I think this is still included in another exam.
Are there any good book to recommend for Swing?
Thank you.

- The new Net Beans IDE Java developer software. Good in theoryNowadays when you obtain the SDK form java.com
you get a new interactive programming environemt
much like the Borland C++ IDE.
Up to now I've been developing applications "the old way"
using the operating system command line method.
that is, javac MyApp.java
Then my computer at home crashed and I decided to install the
JDK on my office computer. This was when I got the new
Net Beans IDE. It all seemed good in theory, having eveything
conveniently in one package, the editing, compiling and
executing of your program. It even promised a way to assemble
Jar files.
The problem is that application programs which compiled just fine
using the Command line compiler (javac MyApp.java) seemed to generate
numerous "Cannot Resolve Symbol" errors on this new IDE thing.
This is despite I had all necessary classes in the same directory.
Another thing, I cannot make Jar files for my applets.
I also han do problems with the command line method.
I just don't understand. What's worse is that there are no readily
available online resources to address such issues.
Thank goodness I didn't have to pay for this thingy.
What did these super-qualified programmers employed by Sun Microsystems
lear in college?
I finally got my home computer up and running again and
I so happend to have an SDK (command line java compiler) from a CD I got
with a Java textbook.
I loaded it onto my computer and I am back in business again.

- JVM parametersWhen using the parameters:
-Xms32m -Xmx200m
What exactly does this do in terms of how much memory is allocated to
the JVM from the system?
Does it initially allocate 32m to the JVM and allow it to grow to 200m
over time? Or does it allocate 200m initially?
Thanks.
