EJBException when binding a map containing an entityContext.getEJBLocalObject()

Question

I am attempting to bind a map which contains keys that point to entityContext.getEJBLocalObject()
in ejbPostCreate. This causes an exception to be thrown, which makes it appear
that BEA is trying to prevent a remote client from getting an error if/when they
lookup since they are not local. Are there any ways to get around this, or do
this differently? We know that this lookup will only occur on the server, so we
would like to store this in JNDI.
Thanks so much, Jennifer
METHOD:
public void ejbPostCreate(int id){ Context initialContext = null; Hashtable ht
= new Hashtable(); ht.put(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
ht.put(Context.PROVIDER_URL,"t3://localhost:7001");
try { initialContext = new InitialContext(ht); } catch (NamingException e) { try
{ initialContext.close(); } catch (Exception ex) { } } Object objref = initialContext.lookup("ABCMap");
if (objref != null){ if (objref instanceof HashMap){ HashMap map = (HashMap)objref;
ABCPrimaryKey key = (ABCPrimaryKey)entityContext.getPrimaryKey(); ABCLocal value
= (ABCLocal)entityContext.getEJBLocalObject(); map.put(key, value); initialContext.rebind("ABCMap",
map); /* exception is thrown */ } } }

Answer 1

Clients of a local bean must be in the same .ear file or same .jar file. Even if you are only looking them
up on the same server, they may not be referenced across application boundaries. So, you may not store them
in the global JNDI tree.
