Hi Edson,
I am using Janino compiler. I have already seen the problem but I'm
still looking for a way to solve it in netbeans. It seems that there's a
portion in the JavaCompilerFactory where it loads the janino compiler using
the Class.forName method (its the org.apache.commons.jci.compilers package).
Had it been classloader.loadClass method, I would have probably solved it
directly by just passing the appropriate classloader.
Since netbeans have a fairly complicated classloading mechanism, it cant
find the janino compiler this way. I have to save the janino compiler and
its related classes into the classpath of netbeans. Since I'll be
downloading the application from a server, I still don't know how to
download these files and save it in the correct classpath automatically.
Well at least there's some hope. Thanks for your reply.
Regards,
Elmo
