I think the default port is 8080
Oh, I think I've described my problem rather weired. I don't mean the port of the client application but the port that I want to connect for the naming service (ejbs, etc.). And the usual jnp-Port is 1099 and within my Client-App. I try to get the initialContext by using this port but it does not work....
'but it does not work.... '
You have no chance of any support unless you describe the problem.
What does your client code look like?
If the client code is using a jndi.properties file what are its contents?
What errors / exceptions are you getting?
The jndi.properties used by the client must not be the one in server/default/conf. The jndi.properties in server/default/conf should never be edited.
