Check the settings in the java.conf.xml file (conf/autoload_config). Make sure it’s referencing a valid libjvm.so  file/path.

Also, be sure to have the freeswitch.jar jar file in the freeswitch/scripts folder. Check also the port you’re using for debugging (8000): is this port being used by another app?

Good luck!

Subject: [Freeswitch-users] Unable to use mod_java.

Hi !

I have been trying to enable mod_java with FS but am having problems. I was able to compile mod_java fine. However FS is having trouble loading the module. It errors out with the following error message:

2012-06-07 20:51:24.058126 [ERR] modjava.c:326 Error creating Java VM!,

I believe I have the CLASSPATH/PATH variables set up correctly in my configuration files. In fact I put in some debug statements in modjava.c. Below is the debug output showing the various variables:

Would really appreciate any ideas from others that may have tried enabling the same?
