Error while deploying a web service on sun app server

[Deepa SN]

Hi,
A Web service is developed for a reservation system. Initially, the methods inside the service didn't contain any parameters. Later, the method signature was chaged by including some parameters to the method. At this point, the code compiles fine. But when tried to deploy it on the Sun App server, an error saying "com.sun.enterprise.deployment.backend.IASDeploymentException: Error while running ejbc -- Fatal Error from EJB Compiler -- jaxrpc compilation exception" is displayed.

Any help on this would be appreciated.

Thanks in advance
