I have started cloudscape as
cloudscape -start and then
I have tried starting j2ee at the command prompt by giving
j2ee -verbose
The server is throwing a null pointer exception and the runtime exception given is "Unable to create POA Id"
Can anyone please help me with this ???

Hi Sree
Don't know how correct I'm, but try this.
POA stands for Portable Object Adapter( a CORBA standard for building server side applications that are portable across heterogeneous ORBs). There are 4 ports being used by J2EE, the fourth port for Naming and Directory Services for Object Request Broker(ORBs) is port=1050. The ORB () underlying the JNDI name server uses this port.
This I think is being used by some other service because of which you are getting that error.
For example : I ran rmiregistry on port 1050
and then started the cloudscape server which runs fine. But when I run the j2ee server I get the following error


Guess you have to uninstall the whole lot of it and redo the process.
I have started both on my system and they are working fine.
Regards
Suneel

Hi Sree
I have tried simulating few other ways of getting the same error and have not got it.
Start your system and remove all additional software which gets loaded at start up. Go to Start - Settings - Control Panel - System - Environment variables. Set only those for J2EE and
Cloudscape. Even after this you could still go to task manager
and end task unrequired software and then try loading cloudscape and j2ee.
Do get back after you have tried it.
Regards
Suneel
