I'm trying to move a JaveBridge'ed project to a new server. Its running PHP w Java throught sun-java6. I don't know how to read java error output and was hoping one of you could point me in a direction to figured what to do on the server to make this app happy.

    Fatal error: Uncaught [[o:Exception]:"java.lang.Exception: CreateInstance failed: new com.elance.proposal.html2image.client.MainBridge. Cause: java.lang.ClassNotFoundException: com.elance.proposal.html2image.client.MainBridge VM: 1.6.0_06@http://java.sun.com/" at:
