I compiled a client.jar that contains DTO's under jdk 1.4, compiling at 1.3 compliant. I have set the serialVersionUID = 1 in each one of the DTO's and all the DTO's implement serializable. The client is running Weblogic 7sp2 and calling an ejb running in a Weblogic 8.1sp2 instance.
Any thoughts? jdk issue? Weblogic issue?
Bleow is the code for the VehicleDTO.
When the client calls the ejb, the following error occurs on the server:
