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
