Starting WL 5.1 after deploying an Entity bean

[Dana Spice]

I cannot seem to figure out why my WL sever will not start after creating my entity bean. Everything seems to be in order, but I can't make sense of the error on startup of WL... Any help?
The WebLogic Server did not start up properly.

It may help to post some of the source you have used to get this error. For example, the xml files you used to generate the bean, and/or the source code.

[Dana Spice]

Below are the two deployment XML files. I would post code, but the EJB is pretty much a generic one created via visual cafe. The error occurred during WebLogic's startup...

Hello Diana,
This kind of exception is raised when one or more classes used by your bean have changed. The server could deploy the bean as there was no problem with the bean per se. But, some file change was not reflected in your bean.
