- What does this mean? (The type xxxx.yyyy cannot be resolved. It is indirectly referenced from required .class files)The class in question is being used just fine a few lines above where
this error is being generated. The only difference is that the
reference generating the error is on a static member function.
Non-static references are working just fine. I am using Eclipse
3.0.1. The static function is showing up in the package explorer, but
does not show up in the editor quick complete window when I type the
class name followed by the member operator. Only the non-static
member functions show up. Any idea what is going on here? The rest
of the project (very large, hundreds of source files!) seems to
compile just fine.

- which VM ?Hi,
I'm a teacher and I wrote some applets for my students. To be compatible
with most browsers they could use I wrote these applets in Java 1.1.
It works fine on IE of Windows 95, 98, 2000, but not on some versions of
Windows XP which require the JVM download.
Some of my students get a very slow modem and I can't ask them for
downloading large amounts of MBytes.
Since I only use the java 1.1 version, where I can find the most little JVM
for this ?
Is there a zip, or autoextractible version of it ?
Thanks a lot.

You might want to try updating to 1.5.0_07-b00. If the problem persists
then please post the trace from that. Thanks.

- Rows affected discrepancyI'm running a simple select query and when I issue it through the Java
ODBC connection it claims that it returned 12883 rows. When I run the
same exact query in Query Analyzer, it says 12922 row(s) affected.
What's the reason for this discrepancy?
Also, is there a method to return the number of rows affected that
would get rid of my manual counter?
Thanks.

- Java3D and NVidia RIVA TNT graphics cardI'm using a Dell Dimension PC with Win98 and a NVidia RIVA TNT graphics
card. After loading Java3D 1.3 and attempting to load
HelloUniverse.html, I get:
"No compatible device found, please switch to other display mode and
try again."
The bottom bar of the IE window displays:
"exception:java.lang.NullPointerException: Canvas 3D: null
GraphicConfiguration"
I tried different combinations of 32 bit color vs. 16 bit color, and
Java3D DirectX vs. Java3D OpenGL.
Any clues?
Thanks,

But you should. Nobody cares if they suck or not. This is about you

But why do *you* complain about *them*? If they can't get you a job,
it's *your* job to do so! Manna doesn't fall from the sky.

That tells me that you should have made more noise. Maybe you find it
irritating. Maybe you despise that kind of people. But nobody cares.
They got a job, and you didn't. It's about priorities.

These are claims you make, but I'd like to question how well these
resumes are tailored, and how well they're presented. Since you don't
have a graphical browser, maybe your word processors aren't too modern,
either. (just assuming, maybe I'm wrong here)

Sure, .doc isn't cool, but if it's what everybody wants, you should get
used to it. It's your choice to stay out in the rain, but you're
complaining about that, so start playing by *their* rules.
It's a problem with several dependencies. If you need a PC with
MS-Word, get one *before* tackling the job application problem. Good
ones are on ebay for cheap.
You pay $20 every month for a shell account. What does it do? Some
file storage, a C compiler, ...? Great, I bet everybody in this ng and
every single CS student has all that on their home computer, running
Linux, BSD or whatever. And it even runs a graphical browser.
For word processing you can get OpenOffice for free, if they don't
accept resumes in TeX.
If you need to, live without web access for a year, save the $20 a
month, and go buy a decent machine then. It seems that sitting at your
shell account, writing news articles here doesn't buy you anything, so
save those $20.

- How to display a "double" in all its precision???Hello,
Here is a code fragment that is very simple... but I can't get it to
work!
public static void main(String[] args)
{
for (int i = 1; i <= 30 ; i++)
{
double x = Math.pow(2, i);
x = 1 + 1 / x;
System.out.printf("For i = %d: %.40f%n", i, x);
System.out.println(
Long.toBinaryString(Double.doubleToLongBits(x)) );
System.out.println();
}
}
All this code is supposed to do is print out the fractions 1+1/2,
1+1/4, 1+1/8, etc. When one prints out the raw bits (see
doubleToLongBits), the code is clearly working.
But on the regular printf("For i...etc"), at i=17 and above, the
numbers get frozen at 16 digits displayed after the decimal point (the
precision). But it's not really the precision, because the bits ARE
changing correctly. What gives???

- An intranet questionAnybody know how to obtain the information of all the hosts that are in
the same local network as mine? For example, on Windows, how can I get
a list of computers' information in the same workgroup?
Computers in the same intranet has the same IP address prefix (such as
192.168.0.1 through 192.168.0.255). Especially I want to get the list
of those hosts' IP addresses.
Is any class in package java.net able to do this job? Hope I clearly
express my problem. Thanks!

java-programmer, setting keys in xmlspy
I would like to assign custom key combinations for xml functions. Some
of the combinations are handled by the menu key, such as alt-w will
open the windows menu. I would like to set that to file/save. I would
also like to set alt-x to quit but it opens the XML menu.
so is there any way to change this behaviour? Other development
environments automatically handle these customizations.
thanks for the help

- Why do JARs made with JBuilder 2006 Enterprise not work outside IDE???Hi all,
I have written a program in JBuilder 2006 Enterprise (Win NT, JRE 1.5)
which works perfectly within the IDE.
However, when I use JBuilder to create a JAR of my project and then try
to run in from the command line it throws the run-time exception
below...
Exception in thread "main" java.lang.SecurityException: class
"Com.package.MyPackage.MyExcpetion"'s signer information does not match
signer information of other classes in the same package
I have used JARs before but never come across this sort of error, maybe
worth adding that the program uses JavaMail to send emails.
More confusing, why does it work in JBuilder, but not outside?!?
Any help would be greatly appreciated, i am stumped!

It's all over the blogosphere and Bill Gates has been quoted as

what is Agloco and will they really pay you for surfing the net?
I too was sceptical when I heard about it but after spending a few

idea but am now thinking it could really work and could really make

This is handled by the JSP container, i.e. on the server side.
The path is hence relative to the JSP application.

css is not JSP includes, but is part of the plain webbrowsing, i.e. handled
from the *client* side.
css is "requested for" by the the browser, i.e. the path is relative to the
visible url.

- What is a "dirty read" ?Hi group,
I am new to JDBC but have idea about Oracle transaction management. I
am confused about JDBC documentation saying "dirty read"s allow
changes made by a trasaction visible to another before it is
committed. What does this mean ? Does it mean that the concurrent
transaction can be from different connections ? If so how is it
possible ? I believe read dirty reads are reads from dirty blocks
which is accessible only by this session.
TIA

- j2ee request resource is not available hello1Hi all,
I have found a solution to a problem that I would like to share.
I am running WindowsXP and J2EE sdk 1.3.1.
I was trying to run the Hello1 servlet example from the J2EE examples
from sun. I found this error message: j2ee request resource is not
available
Then I solved this problem by opening the application in deploytool:
Filling in the following fields:
Hello1App: WebContext-> WAR File = Hello1WAR; ContextRoot = hello1
GreetingServlet -> aliases = /greeting
ResponseServlet -> aliases = /response
This solved the problem and it was running fine.
Hope it helps,

- Database and java.sql.SQLException QuestionsHello everyone!! I am back for some more much need advice and assistance! I
am creating a database for the first time. I am changing some programs I
recently wrote to work with this database that have to do with Salesmen. I
am getting the below error when I compile CreateDatabase.java. In that I am
creating the database SalesDatabase and then creating 5 tables (Users, SType,
Salesman, Sales, Product). The first thing I do is create those tables and
then insert informtion into the SType table and Product table. SType is the
SalesType of a salesman, meaning Entry, Junior or Senior that also has the
bonus in there as another field (.05, .10, .15) and then product has product
1, 2, 3, 4, and 5 with the corresponding price of each. After I do this I
need to read in a text file (SalesInformation.txt) and calculate the sales
based on the information in the database. So here are my questions:
(1) What is the below error telling me, have I not set the database up
correctly?
(2) Am I on the right track with what I have below, should I be reading the
text file as I am or should I change it to be its own method (anything you
tell me would be apprecaited!!)?
(3) Also, other than it not compiling...lol...I am unsure of the salestype
part with element 6 on line 124. I read in ENTRY, JUNIOR or SENIOR from the
salesinformation.txt file so how do I relate that with retrieving the bonus
number from the database?
Ok, I think that is enough questions for now. If anyone needs any additional
information as to what I am trying to do, just let me know and I would be
happy to fill you in!! I appreciate any hints or tips you may be able to
give and I look forward to getting this thing working :)!! Thanks everyone!

- Action selected state in JDK 1.5Hello all!
Does anyone know of or have a solution of how to have automatic
updates for buttons and menu items created from Action's FOR JDK 1.5?
I know that automatic support for it was added in JDK (1.)6.0, however
the requirements for the software I'm developing is Java 5...
When calling new JMenuItem(Action) or JButton(Action), basically any
radio button or checkbox AbstractButton component, calling setEnabled
an the action turns the button AND menu items to gray. I would simply
like to achieve that for the selected state as well: Whenever the user
clicks on a toolbar button OR menu item, the selected state shall be
reflected in the other GUI component, too. As stated above, a solution
is inside the "too new" JDK6.
So, has anybody implemented a solution for this? Maybe some
AbstractAction subclass?
Any help on this appreciated! (directions etc.)
TIA

- hasNext?What is hasNext? I know you use it when you are reading from a file
and it will stop when it has nothing more to read, but how would you
use it? I have seen a couple of different examples of it, but all
they do is make me more confused. I just can't seem to understand
it...can anyone help?

- Simple java question...Hi guys,
please help me with this simple java question.
I'm developing a jsf application but i have a java question.
Suppose i have an authentication bean with 3 attributes,login,password
and team that load the values inserted in a login page.
In another bean i have a method that performs inserting an experiment
into a db.
My prepared statement is like...
pst2.setString(1, name);
pst2.setString(2, team);
pst2.setString(3, platform);
etc...
but i want name is the login attribute and team the team attribute of
authenticationBean.
How can i pass these values to my pst.2setString?
Please help me

Yeah, I think the policy should be consolidated, since java 1.1 is (for all I
know) not packaged or availiable in Debian. Java-package supports nonfree
runtimes starting from 1.3 and above. I assume that most of the software
packaged in Debian these days will require a pretty modern runtime anyway.
So, I'd suggest that the java(X)-runtime virtuals are removed in favour of a
general "j-word-runtime" virtual to be provided by all runtimes capable of
running programms written in the Java programming language.
I propose using "j-word" instead of "java", because that is a time-honoured way
of abbreviating four letter words that can not be said freely in English.[1]
cheers,
dalibor topic
[1] As Sun Microsystems holds and and actively defends their Java(TM) trade
mark, I would not recommend calling Kaffe a Java(TM) runtime, because, frankly,
according to Sun Microsystem's rules for the usage of the trade mark, it is not
a Java(TM) runtime.
And that's fine by me, I don't feel that trying to rub off Sun's trade mark
investment is a fair thing to do.[2] You can see on the kaffe.org web site how
the Kaffe project tries to draw a clear line between Kaffe and Sun Microsystem's
implementation. In order to avoid confusing people who dearly want the "Java(TM)
Desktop System" GNU/Linux distribution, for example, rather than a free software
runtime environment for programms written in the Java programming language (that
is a safe use of the term "Java", btw. ;).
[2] Just like I don't feel that Sun Microsystems attempts to market some of
their clearly proprietary software as Open Source are a fine thing to do, like
they tried to do with Java3D or JAI. See my comment at
http://weblogs.java.net/blog/editors/archives/2005/02/working_with_th.html for a
reference.

- Skyway Builder Rocks! I'm building J2EE apps without writing code....I've been using this development platform for the past month and I
can't believe how easy it is to build JAVA applications and web
services. This thing is powerful and a huge time saver. I havn't had
to write a single line of code yet. If you havn't tried it, do
yourself a favor and download it..it's FREE.

- Can't avoid "References to generic type List<E> should be parameterized" warning here can I ?Hi,
I'm writing some kind of gateway between 2 packages, whose a
few classes have the same name (I need to bind these classes).
So I'm retrieving the attributes of my source class1 and set my
equivalent class2 in the other pkg with these attributes when
methods names -and attributes- match.
Excerpt from my method:
1 public my.persistent.Pst mapFromProtocol(my.protocol.Pst src)
2 {
3 my.persistent.Pst target = new my.persistent.Pst();
4 for (Iterator<my.protocol.Remark> it =
src.getRemark().iterator(); it.hasNext(); )
5 target.getRemark().add(it.next());
6
7 ... //many other attributes/objects to set too
8
9 return target;
10 }
In RAD the line 5 is underlined in yellow and it says "Type safety:
The method add(Object) belongs to the raw type List. References
to generic type List<E> should be parameterized".
Is there a way to avoid this warning in my case, as I can't
instantiate
a List<Remark> lr = new ArrayList() of course... (because I have no
method setRemark() in target)
Thanks.
Regards,
Seb
