[markfrench]

Hi,

I have been tring to migrate code from a 4.0.3SP1 and EJB3 RC3 and each time I try to run my tests the following exception occurs:

Caused by: java.io.InvalidClassException: javax.ejb.EJBException; local class incompatible: stream classdesc serialVersionUID = 2512003687642492863, local class serialVersionUID = 796770993296843510

Any ideas as to the cause?

migrating from what to what? Did you read the installation docs? The client libs need to be patched if you are ugrading from SP1 RC3 to RC5.
