Looking up Identical EJB both locally and remotely

Question

prior to posting this request, i have read and
attempted multiple solutions to this problem
suggested in the forums to no avail.
if i have the same EAR, which contains both
an EJB Component and a WAR, deployed to multiple
servers, is it possible to look up an EJB both
locally and remotely?
for instance, on the server performing the lookup,
EJB A is deployed. i successfully look it up
via the following call:
InitialContext context = new InitialContext();
Object ref = context.lookup(name);
return javax.rmi.PortableRemoteObject.narrow("EJBA", EJBAClass.class);
subsequently, i try to lookup the same ejb
on a remote server by performing the following
calls:
Properties environment = new Properties();
environment.put("java.naming.factory.initial", "com.evermind.server.rmi.RMIInitialContextFactory");
environment.put("java.naming.provider.url",
     "ormi://remoteserver:23791/application");
environment.put( "java.naming.security.principal", "user");
environment.put( "java.naming.security.credential", "password");
jndiContext = new InitialContext(environment);
Object ref = context.lookup(name);
return javax.rmi.PortableRemoteObject.narrow("EJBA", EJBAClass.class);
however, i either receive an authentican exception, saying "user"
doesnt have access to allication "application", or a null pointer
exception int the RMIInitialContext.
on my local application, i have defined my ejbs in the web.xml
as defined by the spec. the ejb component is marked as remote="false"
in my orion-application.xml as well.
the version of oc4j is 1.0.2.2.1.
any directinon on this would be greatly appreciated.
thanks,

Answer 1

as a follow up to my own question, using a application
client, outisde of the web application i can
successfully look up my ejbs locally and remotely.
however, from within the web application, i constantly
receive a ClassCastException.
if no one can tell me how to resolve this, could someone
let me know if they have in fact looked up the
same EJB, both deployed locally and remotely, from the
same web application.
thanks,
