Ok, thanks. Now I can access the jar file. It was the error message that
threw me as it doesn't in any way indicate what the error might be.
Do you think this is related to why I can't create a Java object of type
GZIPInputStream? When I try to do this an exception is thown and the log
file contains:
EXCEPTION cJBExceptJavaException : NewObjectA
ERR <IDL_JBCreateJavaObject return=(nil)
0x821c618 IDL_JBDeleteCharBuffer Del

It appears on linux there is a problem with the IDL-Java bridge using jar
files created with ZIP compression. The IDL-Java bridge works fine with ZIP
compressed Jar files on Mac OS X, Solaris Sparc 8, and Windows 2000.
I have logged an issue here at RSI for development to look into the problem.
For now the workaround is:
Unjar the file
or
Build the jar file without ZIP compression(use the 0 flag). The
jbexamples.jar file provided in the distribution that works on linux was
built with the following command:
jar cf0
