EJB with Weblogic 5.1

[cris abanades]

When I call a EJB in a servlet, it doesn't work but if I do this in an application client that calls EJB, it works perfectly.
What is the problem?
The exception is:
java.lang.ClassCastException at com.sun.corba.se.internal.javax.rmi.PortableRemoteObject.narrow(PortableRemoteObject.java:296)

p2.put(Context.INITIAL_CONTEXT_FACTORY, "weblogic.jndi.WLInitialContextFactory");
p2.put(javax.naming.Context.PROVIDER_URL,"t3://"+servLoc);

public void init(ServletConfig config) throws ServletException {
if (homeUMon==null | | remoteUMon==null) {
java.util.Properties p2 = new java.util.Properties();
java.util.Properties p = new java.util.Properties();

try {
InitialContext ctx = new InitialContext(p2);
Object objref = ctx.lookup("UserMonitor");
homeUMon =(UserMonitorHome)PortableRemoteObject.narrow(objref,UserMonitorHome.class);
} catch (Exception NamingException) {
NamingException.printStackTrace();
}
try {
remoteUMon = homeUMon.create();
} catch (Exception NamingException) {
NamingException.printStackTrace();
}
