java.rmi.UnexpectedException: Failed to parse descriptor file; nested exception is: java.rmi.server.ExportException:

问题

I have upgraded my web application from java6 to java7. I have deployed web tier, ejb tier and web service tier on weblogic 10.3 successfully. Everything works fine except stateful ejb. During these ejb invocation , I get following exception on server logs.

java.rmi.UnmarshalException: cannot unmarshaling return; nested exception is: 
    java.rmi.UnexpectedException: Failed to parse descriptor file; nested exception is: 
    java.rmi.server.ExportException: Failed to export class SearchAccountSessionBean_qa86w0_EOImpl problem with rmi descriptor signature getFilterCount([Lcom.abc.SearchResultFilterName;)RemoteMethodSet=[setPrimaryKey(Ljava.lang.Object;), ......

Can anyone advice what may be the root cause. my ejb version is 2.0.

Sometimes the EJBCompilerCache in weblogic will have the old bean details resulting in the above said error. Just clean the weblogic application server tmp and cache folders and try again.
