Error in publishing Web service

I have a WSDL file from which I have created Server Side Code Skeleton. Now after modification of these skeleton Java classes I have deleted the WSDL file from the project folder. Now, I am trying to prepare a web service for these classes. I m using Axis engine and apache tomcat 5.5 for this which is embedded with the eclipse. But when I start this I m getting the following error.

IWAB0489E Error when deploying Web service to Axis runtime axis-admin failed with {http://schemas.xmlsoap.org/soap/envelope/}Server.userException java.lang.reflect.InvocationTargetException

Can any one help. What is this error??
