Http 503 error in servlet connection

I am using the Apache tomcat server for webserver and OPEN NMS server(in separate system). I am modifying the OpenNMS jar file to support our application. But if I want to add some code for Assets to add/modify the Assets table in OpenNMS DB then it is giving "HTTP 503 error". For other module (alarm), the same is working but for Assets it is giving error.

A 503 error is often generated by Tomcat when an exception occurs during processing the request. Something went wrong inside the application -- probably in the code you added. Typically, Tomcat shows you a stack trace in the browser. If not, then simply look at the catalina.out log file in (Tomcat home)/logs and scroll towards the bottom. You should see some stack trace.
