ScribbleWindow: NoClassDefFoundError

[Stephen Williams]

Hi,

I'm trying to get to grips with using java with qt bindings and have a couple
of small problems. I would be grateful if somebody could point me in the
right direction.

I've installed both koala and qtjava. Both the .jar files are
in /use/kde/3.4/lib/java/

How can I add both the .jar files to my classpath? Passing
"-cp /usr/kde/3.4/lib/java/qtjava.jar" works fine, but as soon as I want to
pass in two paths like this:
"-cp /usr/kde/3.4/lib/java/qtjava.jar;/usr/kde/3.4/lib/java/koala.jar", bash
says that there is not such file or directory (but there clearly is).

Then, why does the kdejava-readme say that to run the program you need to go
"java Main"? Shouldn't it be "java ScribbleWindow" (with classpath)?

If I just include qtjava.jar in my classpath, ScribbleWindow will compile, but
java won't run it, outputting: "Exception in thread "main"
java.lang.NoClassDefFoundError: ScribbleWindow". Why is this the case, as the
class ScribbleWindow is clearly in ScribbleWindow.java?

Thank you very much for your help to get me going,

Stephen

Hi Stephen,

you need to use the colon ":", not the semi-colon ";" to separate entries on
your classpath. This is different from MS Windows.

Bye,

Hi!

Instead of

Post by Stephen Williams
"-cp
/usr/kde/3.4/lib/java/qtjava.jar;/usr/kde/3.4/lib/java/koala.jar"

try rather:

"-cp /usr/kde/3.4/lib/java/qtjava.jar:/usr/kde/3.4/lib/java/koala.jar"

I.e. use the colon instead of the semicolon to separater classpath
entries.

HTH,

Robert
