Assertion Error while connecting to Remote EJB in WebLogic

Hi,

Can anyone help me with thie error.

Iam getting the following error when Iam trying to connect to to a EJB running on Weblogic .

What might be the possible causes.

This the code where Iam getting the error.

String custData;

com.o2.registration.adapter.CompanionAdapter stubCustomer = (com.o2.registration.adapter.CompanionAdapter) getRemoteInterface();

custData = stubCustomer.getUserDetails(customerNumber, username, domain);

I cannot use the serial version UID since the environments might change from development to test to production.

I tried to google the error.,but I have not got any satisfactory answers. Can anyone possbily give me all the possible reasons that might cause this error.

getUserDetails() is in CompanionAdpater.jar file.
