Help Please: Problems with JNDI

[Oliver Rode]

I have problems to get the InitialContext for JNDI.

The host running der WAS is spock (IP = 192.168.0.5).

InitialContext-Properties:

{java.naming.factory.initial=com.ibm.ejs.ns.jndi.CNInitialContextFactory,

java.naming.provider.url=iiop://spock:900}

When I execute the following line of code

initContext = new InitialContext(properties);

it throws this Error:
