OutOfMemoryError when connecting to BC4J deployed as EJB in Oracle 8i

Question

I have deployed a simple Application Module as an EJB in the Oracle 8i. I tried to connect to it with the following code:
Hashtable env = new Hashtable(2);
env.put(Context.INITIAL_CONTEXT_FACTORY, JboContext.JBO_CONTEXT_FACTORY);
env.put(JboContext.DEPLOY_PLATFORM, JboContext.PLATFORM_EJB);
env.put(JboContext.CONNECTION_PORT, "2481");
env.put(Context.SECURITY_CREDENTIALS, "jd");
env.put(Context.SECURITY_PRINCIPAL, "jd");
env.put(JboContext.ORACLE_SID, "ORA8I");
env.put(JboContext.HOST_NAME, "dev51");
env.put(JboContext.APPLICATION_PATH,"test/jd/ejb");
ApplicationModule appMod1 = null;
try
System.out.println("Setting up Initial Context...");
javax.naming.Context ic = new InitialContext(env);
System.out.println("Doing LookUp...");
ApplicationModuleHome home1 = (ApplicationModuleHome)ic.lookup(amName1);
System.out.println("Calling create..." + home1.getClass());
appMod1 = home1.create();
While running the above code, I get an exception at home1.create() :
Setting up Initial Context...

Trying to connect the same through an infobus data form results in a similar exception :

Hi:
I went into the same problem as well.
Does anyone know what might causes this?
Thanks,
