I'm afraid I don't know how to help you with mod_jk but if you search the forums for the words 'port' & '7080' you'll find some threads that might help you. I don't think it's a problem with zmtrainsa but this error seeme to give a clue:
Code:
Exception in thread "main" com.zimbra.soap.SoapFaultException: system failure: Request not allowed on port 7080
