Found an interesting site on data mining (my profession) that also has a lot of java resources on it (my other profession!). Not sure if there are any java jobs, but it does have a complete list of job search engines.
Check out www.data-mining-jobs.com
Also another site that I have been surfing lately is ...
www.justjavajobs.com
Happy hunting.

How long should I work in the Java field before I consider going for my SCJA cert ?
I've already gotten my SCJP and SCJD and am a pretty competent programmer, but going through the posts here it seems to be taking it to the next level! Looks very challenging. What are everybody's opinions on this?

Well, I kept banging my head on this. I took the hints from your posts and I started looking at the characters individually.
I just discovered that one of my " characters was a funny looking " (almost italics looking) I don't know how it happened or how it got there. Heck, my keyboard doesn't even make that character. Anyways, I typed over it and voila, it works.
I wish that I had first tried the "encoding="UTF8" that was suggested. I'm interested to see if that would work.
Thanks for all your help! Your posts put me onto the solution.

Here is my build.xml
<?xml version="1.0"?> <project name="visualechoes" default="compile" basedir="c:/java/Don"> <!-- ===================================== --> <!-- Global properties --> <!-- ===================================== --> <property name="jdk" value="c:/java/j2sdk1.4.1_01" /> <property name="name" value="visualechoes" /> <property name="source" value="${basedir}/Source" /> <property name="build" value="${basedir}/build" /> <property name="baselib" value=�${jdk}/jre/lib" /> <property name="dist" value="${basedir}/dist" /> <property name="docs" value="${basedir}/docs" /> <property name="api" value="${docs}/api" /> <property name="tomcat" value="/tomcat/webapps/aag/WEB-INF/lib" /> <property name="tomcat-jar" value="/tomcat/webapps/aag/jar" /> <!--===================================== --> <!-- Init --> <!--===================================== --> <target name="init" > <tstamp /> <mkdir dir="${build}" /> <mkdir dir="${api}" /> <mkdir dir="${dist}" /> </target> <!-- ===================================== --> <!-- Compile --> <!-- ===================================== --> <target name="compile" depends="init" > <javac srcdir="${source}/GeneralUtilityPackage" destdir="${build}" <!-- <classpath> <pathelement location="${baselib}/mysql_uncomp.jar" /> <pathelement location="="${baselib}/struts.jar" /> </classpath> --> </javac> </target>


c:\ant

OK, so what's the best book out there on ANT ?
Which books should I avoid?

I want to compile the source files from one
directory, but have the ".class" files get
output into another directory.
In other words...
I want to compile, using "javac" the file
c:\fred\test.java
But I want the output to go into ...
c:\joe\test.class

What command line options do I use? Right now,
when I compile, the class file goes into
c:\fred\test.class
nomatter what I do.
So confused!

For some reason, I looked at the docs a thousand times and kept overlooking "setIcon".
It worked, of course!
Thanks for the help, I'll go get my eyes
checked now!

I'm writing an application that displays "playing cards". I have gif files for all the cards, such as "aceclubs.gif", "sevendiamonds.gif", etc.
I'm displaying the cards using JLabel like this ...
JLabel fred = new JLabel("hello",
cardImageIcon,
JLabel.CENTER);
(where cardImageIcon is an image icon).
Now, when I press a button, I want to change
the card displayed to a different card.
Can't seem to do it. It seems that Java lets
me change the text (i.e. "hello" to "goodbye")
but won't let me change my image from
"aceofhearts.gif" to "twospades.gif")
If not ImageIcon ... what should I use?
Should I use something other than JLabel?
Thanks!

I called the "help desk" here at work and they were stumped.
Tech Support finally had me reinstall "SERVICE PACK 2" for Microsoft Windows 2000.
Now it works!
Therefore, I must have had a corrupted install file. Hope that helps others in my situation!
By the way, Microsoft has Service Pack 3 out, but our company hasn't officially tested that yet, so they didn't want me to upgrade.

Nope. The AWT code didn't work either. I am getting more and more convinced that this is a bug with Windows 2000.
Anybody heard any bugs that might cause these problems?

The JFrame never even pops up.
I just type
"java Deck"
then I hit the <CR>
then it just sits there. No window pops up. No nothing! I figured it had something to do with no swing in my class path but I don't think that's the problem with this because this version doesn't require swing in the classpath.

Here is my path ... (or at least part of it )
Path=C:\java\j2sdk1.4.1_01\bin;C:\java\j2sdk1.4.1_01\jre\bin; etc.
The java stuff is FIRST in my path. I have all of my java stuff hanging off of a "java" directory.
Here is my program ....
import java.lang.Math ; import javax.swing.* ; import java.awt.* ; import java.awt.event.* ; public class Deck extends JFrame { public Deck() {} public static void main( String arguments[] ) { Deck D = new Deck() ; D.Main( arguments ) ; } public void Main( String arguments[] ) { JFrame frame = new JFrame( "Hello" ) ; Container frameContent = frame.getContentPane() ; frameContent.setLayout( new BorderLayout() ) ; JButton exitButton = new JButton( "exit" ) ; frameContent.add( exitButton , BorderLayout.SOUTH ) ; frame.pack() ; frame.setVisible( true ) ; } }
When I run this from the command line( C : ) Prompt ,
it looks like this...
== == == == == == == == == == == ==
c:java Deck
x
== == == == == == == == == == == ==
Assume that the "x"is a blinking curser
which implies that my program is running.

Help!
I have a new computer with WINDOWS 2000
I just downloaded and installed j2sdk1.4.1_01
I've been away from Java for a while, but near as I can tell, I don't need to have a CLASSPATH to use Swing (am I wrong?).
When a run a simple "Hello World" program, everything is fine.
When I try to run a simple JFrame program with an exit button, then my program hangs. A friend of mine running j2sdk1.4.1_01 on NT 4 has no problems (he also has no CLASSPATH set).
Is there a problem with Windows 2000 that I don't know about?
Help! Please! I'm having Java withdrawls !!!

I have awaited your book for many months. Now that it's out, I am already hearing good (great!) things about it. I'll be purchasing it this week (unless I win the book giveaway).
As for Sybex, I am skeptical that it will be any good. I purchased Philip Heller's book on the "SCJP/SCJD" exam in order to prepare for my "SCJD" certification. I found it next to worthless. He'll not get my business again!
Has anybody who purchased Sybex found an improvement in the quality over the last book?

Count me in!
I can also test in my spare time
