I have a set of backend beans (session and entity) which forms the core of the application

I have several front end apps which uses the backend, these are either wars or jmx mbeans

Functionally everything works fine, however everytime I change the EJBs and redeploy, I have to re-deploy the front end apps before they can talk to the EJBs again.

Is this normal behaviour?

Or am I missing some configuration somewhere?

thanks
