reflection use on home/proxy
Hello !
I'm trying to perform some common code to invoke method on home computed with the reflection API (code without try/catch):
Object homeref = initial.lookup(compName);
Class xClass = homeref.getClass();
InvocationHandler invctHandler = Proxy.getInvocationHandler(homeref);
Method findByPrimaryKey = xClass.getMethod("findByPrimaryKey", new Class[] {scopedAidClass});
object = invctHandler.invoke(homeref, findByPrimaryKey, new Object[] {scopedAid});
at runtime I get the following exception:
15:32:52,378 INFO [STDOUT] homeref class is $Proxy134
15:32:52,388 INFO [STDOUT] Sucessfull xClass.getMethod findByPrimaryKey

I have define correctly the ejb-external-ref to be able to use the bean on which I'm invoking the home.
I know somewhere the code has to be downloaded into the proxy. So I tried to narrow the homeref with the PRO though in local:
Object homestub = (Object)PortableRemoteObject.narrow(homeref, thisHomeClass);
without any effect, still getting the same proxy and getting the same exception at runtime.
Thank you for any help.
seb.
