[b]Periodic[/b] error using PortableRemoteObject.narrow

Question

I am trying to access a session bean on an oracle9ias(903) running on a windows 2000 server.
Well I am actually accessing several beans, but on some of the beans the code works and on some it don't even though the code is alike. There is no execptions thrown but the LabelTypeDAOHome is null and I get a NPE when calling create on it.
public static Context getInitialContext() throws NamingException, MissingResourceException
Hashtable env = new Hashtable();
String init = getResourceBundle().getString("INITIAL_CONTEXT_FACTORY");
env.put(Context.INITIAL_CONTEXT_FACTORY,init);
String principle = getResourceBundle().getString("SECURITY_PRINCIPAL");
env.put(Context.SECURITY_PRINCIPAL,principle);
String credential = getResourceBundle().getString("SECURITY_CREDENTIALS");
env.put(Context.SECURITY_CREDENTIALS,credential);
String url = getResourceBundle().getString("PROVIDER_URL");
env.put(Context.PROVIDER_URL,url);
env.put("dedicated.rmicontext","true"); // vigtig ifm web access!
return new InitialContext(env);
private LabelTypeDAO getLabeltypeDAO() throws NamingException, RemoteException {
LabelTypeDAO labeltypeDAO = null;
if (context == null) {
context = getInitialContext();
if (labeltypeDAOHome == null) {
LabelTypeDAOHome labeltypeDAOHome = (LabelTypeDAOHome)PortableRemoteObject.narrow(context.lookup("LabelTypeDAO"), LabelTypeDAOHome.class);
try {
labeltypeDAO = labeltypeDAOHome.create();
} catch(Exception ce) {
throw new RemoteException("Could not create LabelTypeDAO.", ce);
return labeltypeDAO;
The funny part is that it doesn't happen on all the sessionbeans.
Could it have something to do with what happens on deployment (e.g internal wrapping).
There is no exception thrown untill I call labeltypeDAO = labeltypeDAOHome.create();
This code is in a java class instantiated in a jsp page.

Found it. It was my own stupid mistake. I had 2 references to the same variable name, one to an instance variable and one to a local variable and I ofcourse referenced the wrong one.
