[Freeswitch-users] mod_java - java.lang.NoClassDefFoundError

[jonathan augenstine]

Damjan,

Thanks for the reply.  I had already worked through the issues of the -D
option not allowed twice and CLASSPATH being ignored.  I am successfully
launching the fs_ivr class (yes, I do intend to use a jar file) but I have
hit another snag (see trace below).  It appears the app is not finding the
native interface library.  Where do I declare that path?

Jonathan
