I have two EAR files (A and B). Each contains a standard Stateless Session Bean among
other things. Bean a in EAR A makes a standard EJB call to bean b in EAR B.
We have found that hot deploying either of these EARs without the other causes
problems. The following exception is generated:
Caused by: javax.ejb.EJBException: Invalid invocation, check your deployment
packaging, method=public abstract
org.jtc.jtrace_udc20interface.jtc_adapter.api.JTC_UDC20AdapterRemote
org.jtc.jtrace_udc20interface.jtc_adapter.api.JTC_UDC20AdapterHome.create() throws
java.rmi.RemoteException,javax.ejb.CreateException
at org.jboss.ejb.StatelessSessionContainer$ContainerInterceptor.invokeHo
me(StatelessSessionContainer.java:632)
at org.jboss.resource.connectionmanager.CachedConnectionInterceptor.invo
keHome(CachedConnectionInterceptor.java:205)
In testing this, we have found that if we hot deploy EAR B, wait one deployment scan
and then hot deploy EAR A, the same error occurs. However, if we hot deploy EAR A and
then EAR B one scan later, everything works normally. In addition, hot deploying them
both in the same scan cycle works properly.
I'm not sure what causes this, but I have duplicated it with several combinations of
beans. Every logical cause that I can think of does not seem to hold water in the
case of a simple hot deploy of EAR A, which fails. I can certainly imagine failure
when hot deploying EAR B without A. However, there is no circular dependency, so A
should be able to be hot deployed without B. It is also strange that I can deploy A
then B, but not B then A.
I would realy like to hot deply A without B as B has a wider number of clients and
changes much less frequently.
Anyone have any ideas what is causing this and if there is a work-around other than
always hot deploying both? Combining the beans into a single EAR is not an option as
they are created by different teams.
