Caching home references

[morphace]

Hi all,

I'm facing the following problem:

my ServiceLocator caches the (local)home references of my EJB's (of course).

When I redeploy my EJB's, those references get invalid. If I invoke a finder on these references I get a NullPointerException.

Is there a way, to get out, if a home reference is valid or not, so that I could invalidate my cache ?

Thanx

I forgot to mention, that my ServiceLocator is implemented as Web-Service (JBoss.net), which means, that it isn't an EJB.
