Hi folks,
I have two applications APP1 and APP2 packaged in two EARs and deployed in
the same Tomee.
APP1 is exposing a local and remote interfaces, APP2 a remote interface
which invokes APP1 interfaces.
As the two apps share the same JVM, I thought pass through local interface
to avoid RMI overhead ... but I am stocked with cast exception :
java.lang.ClassCastException: com.sun.proxy.$Proxy216 cannot be cast to
com.app1.service.MyLocal

here is a snippet of someMethod code :
final Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.apache.openejb.client.LocalInitialContextFactory");
MyLocal l = (MyLocal) new InitialContext(p).lookup("MyLocalLocal");
The use of PortableRemoteObject.narrow does not fix the problem !
Any hint ? Thanks in advance.
NB : There is no problem when invoking remotes.
