Ubuntu Dapper, kernel 2.6.15-27-386, java jre is 1.5.?
Version 1.5.0 (build 1.5.0_06-b05) - latest from Dapper repository

Install the Java Runtime Environment from Sun. The one included with Ubuntu doesn't have a GUI toolkit.

apt-get install sun-java5-jre

It was the Sun jre 5.0 I installed - but your post sent me searching - I found this via synaptic:
libgcj7-awt
Not part of the package or a dependency.

It runs now.
No all I have to do is work out how to use it properly.

Thanks.

But died.

Stopped sb
Changed the sclient.conf for the server to localhost
Had the gui up.
sb2.5 tried to report
Got this:

ian@tqft:/media/hde1/home/ian/sb$ java -jar SBQueue.jar -g
Segmentation fault

Ok I probably haven't set it up right so are there detailed instructions?

Yes I have read the readme.txt do I need to do so again?

"Segmentation fault" comes from the JRE, not my app. "which java" are you using? (Run that command in quotes.)

You could also try, e.g. "java -jar SBQueue.jar -s -t", which won't start the GUI.

Already latest jre

ian@tqft:~$ sudo apt-get install sun-java5-jre
Reading package lists... Done

sun-java5-jre is already the newest version.

Not very useful

ian@tqft:~$ which java
/usr/bin/java

Is it distro/packaging related?
ian@tqft:~$ java -jar SBQueue.jar -s -t
Failed to load Main-Class manifest attribute from SBQueue.jar


ian@tqft:~$ uname -a
Linux tqft 2.6.15.7-ubuntu1-tqft #1 SMP PREEMPT Mon Nov 20 20:02:49 EST 2006 i686 GNU/Linux
Is a standard Ubuntu-smp kernel - no patches - just compiled locally

It's really weird that "java -jar SBQueue.jar -g" would bring up the GUI, but "java -jar SBQueue.jar -s -t" would say "Failed to load Main-Class manifest attribute from SBQueue.jar". If the second command did, so should the first.

I still think that's the wrong copy of Java. When I say "which java" on my old Red Hat 9 machine, it says "/usr/java/j2sdk1.4.1_01/bin/java". You might see if there's anything in /usr/java. If not, try:

locate java | grep "/java$"

If that doesn't work, you might have to run updatedb first. If it does, see if anything besides /usr/bin/java pops up.

Lets play chase the sym link
usr/bin/java/jvm
usr/lib/jvm/java-1.5.0-sun/jre/bin/java_vm
usr/bin/java/java
/usr/lib/jvm/java-gcj/jre/bin/java


ian@tqft:/usr/lib/jvm$ ls
java-1.4.2-gcj-4.1-1.4.2.0 java-1.5.0-sun java-1.5.0-sun-1.5.0.06 java-gcj

No wonder it is confused
