and please find the following java.conf.xml file.

Any Idea why i am getting the error?

The error ("Module load routine returned an error") means the module itself has an error during its startup there are 4 places in the module loading that it would error out: switch_core_new_memory_pool load_config create_java_vm exec_user_method Most likely obviously one of the last 3, load_config will always log something before returning an error status same for create_java_vm, add some additional output to modjava.c should be able to help you track it down. Additionally turn your console log level to debug, and try reloading mod_java to make sure you are not missing any error messages. ~Mitch On Tue, Feb 8, 2011 at 9:00 AM, Derrick Albers <derrick.albers@gmail.com>wrote:

I am trying to load the mod_java, I get the following error: [ERR] modjava.c:124 Error loading /usr/java/jdk1.6.0_23/jre/lib/i386/client/libjvm.so 2011-02-08 10:52:37.540045 [CRIT] switch_loadable_module.c:882 Error Loading module /usr/local/freeswitch/mod/mod_java.so

I have verified that the libjvm.so does exist and is in that location, I have tried everything I can to force this load, please help!
