App client can't instantiate the initial context factory

Question

hi
i wrote an application client and a stateless session bean that i deployed with the deploytool from sun to the j2ee application server. now when i start my application client i get the following message:
NoInitialContextException: Cannot instantiate class: COM.sun.enterprise.naming.SerialInitContextFactory. Root exception is java.lang.ClassNotFoundException: COM.sun.enterprise.naming.SerialInitContextFactory
at java.net.URLClassLoader$1.run
my jndi.properties looks like this:
java.naming.factory.initial=COM.sun.enterprise.naming.SerialInitContextFactory
java.naming.factory.url.pkgs=COM.sun.enterprise.naming
and my server runs on the same computer as the client. the classpath variable is set to the j2ee.jar file ( and this file contains the selected initial factory ). i could not understand why i get this errormessage. has anyone a idea?

thanks to all
now i got it working. i'm using the orion application server and to get access from a remote computer ( outside the application server ) i have to set the environment properties in the following way:
Properties prop = new Properties();
                    prop.put(Context.INITIAL_CONTEXT_FACTORY,"com.evermind.server.rmi.RMIInitialContextFactory");
                    prop.put(Context.PROVIDER_URL,"ormi://localhost/TestBean02");
                    prop.put(Context.SECURITY_PRINCIPAL,"admin");
                    prop.put(Context.SECURITY_CREDENTIALS,"123");
InitialContext initial = new InitialContext(prop);
Object objref = initial.lookup("MyBeanel");
home = (TestBeanHome)PortableRemoteObject.narrow(objref, TestBeanHome.class);
this works, the client needs only the j2ee.jar and the orion.jar in the classpath.
