EJB Method execution error - HELP

· I Successfully established a connection to an EJB server specified in the Alias (wm.EJB.ConnectionToServices:aliasToConnection)
· Successfully retrieved the EJB with which the service will interact (wm.EJB.EJBServices:retirieveEJB)
· But, when I am invoking an EJB Method (wm.EJB.EJBServices:invokeEJBMethod), I am getting the following error in the output variable ‘statusMessage’ :

EJBServices.invokeEJBMethod - beanWrap.invokeMethod threw this: type(com.wm.pkg.ejb.EJBException), msg(; nested exception is: java.rmi.UnmarshalException: Incoming message header or abbreviation processing failed ; nested exception is: java.io.InvalidClassException: javax.ejb.EJBException; local class incompatible: stream classdesc serialVersionUID = 7xxxxxxxxxxxxxxx, local class serialVersionUID = -9yyyyyyyyyyyyyyyy)

Can any one tell me why this error?

Thanks,
Sunny

Has the EJB client changed? If so, you may need to deploy an updated EJB client jar into your IntegrationServer\lib\jars folder.
