Summary: EJBLocalHome interface NOT passivateable
Initial Comment:
The EJB 2.0 spec says about SFSBs (in 7.4.1, page 71) that
references to EJBLocalHome interfaces can be left in the
non-transient fields to be passivated by the container.
Well, I get following exception thrown when my SFSB gets
passivated:
PassivatorQueue [ERROR] EXCEPTION
java.rmi.ServerException: Could not passivate; nested
exception is:
java.io.NotSerializableException:
org.jboss.ejb.plugins.local.BaseLocalContainerInvoker$HomeProxy

The place where this is missing from are
org.jboss.ejb.plugins.SessionObjectInputStream and
org.jboss.ejb.plugins.SessionObjectOutputStream but for them to
be able to serialize/deserialize local interfaces some support has
to be added to the framework. I propose the following:
Create 4 new interfaces that will be used internally by the JBoss:
//
// analogue to javax.ejb.Handle but for local interfaces
//
public interface LocalHandle extends java.io.Serializable {
// obtain EJBLocalObject reference represented by this
handle
public EJBLocalObject getEJBLocalObject();
}
//
// analogue to javax.ejb.HomeHandle but for local interfaces
//
public interface LocalHomeHandle extends java.io.Serializable {
// obtain EJBLocalHome reference represented by this
handle
public EJBLocalHome getEJBLocalHome();
}
//
// extension to javax.ejb.EJBLocalObject interface that adds a
method to obtain a handle
//
public interface EJBossLocalObject extends
javax.ejb.EJBLocalObject {
// obtain a LocalHandle for this EJBossLocalObject
public LocalHandle getLocalHandle();
}
//
// extension to javax.ejb.EJBLocalHome interface that adds a
method to obtain a handle
//
public interface EJBossLocalHome extends
javax.ejb.EJBLocalHome {
// obtain a LocalHomeHandle for this EJBossLocalHome
public LocalHomeHandle getLocalHomeHandle();
}
... then use EJBossLocalObject & EJBossLocalHome for the
various implementation classes internally in JBoss instead of
standard EJBLocalObject & EJBLocalHome (for proxies) and create
some analogues implementations of LocalHandle and
LocalHomeHandle interfaces as done with remote interfaces in
org.jboss.ejb.plugins.jrmp package...
