Problems with Java Processes starting

I performed a Java Add-In installation and originally had the java processes (jcontrol and jlaunch) running. When I now restart the instance these processes are not starting and I don't receive anything in either the dev_jcontrol, dev_dispatcher, dev_server0, and dev_sdm trace files. It is like the java instance isn't even attempting to start. I know this information is pretty vague but where do I begin to troubleshoot this type of problem?
