[jboss-user] [EJB 3.0] - Hot-Deployment-Problem

[skidiver]

Hello there,

there's a problem with the hot deployment on JBoss 4.0.5.GA.
I deploy a ejb-jar that contains a simple stateless session bean und a simple entity bean (ejb3). First time i call a session bean's method it works fine. If i do some code changes and redeploy the jar, the same operation fails with the following client stacktrace:

     [java] javax.ejb.EJBException: java.lang.IllegalArgumentException: Wrong target. class com.company.project.PersonFacadeBean for public com.company.project.PersonPK com.company.project.PersonFacadeBean.insertPerson(com.company.project.Person)

If i stop JBoss and restart it, the operation works fine. Same problem apears, if i delete the jar before reploying it. What's the problem ?

Thx, Malte
