GUEST: Adding a server

GUEST: This nullpointer exception occured when trying to add an server to netbeans. Exactly after clicking on the "Add Server" button. Tools - Servers - Add Server

This problem occured after installing jdk 6 update 12, with jdk 6 update 11 there wasn't any problem.

GUEST: i want to add tomcat server externally to netbeans, but this message keep on showing

GUEST: Server -> Add Server

GUEST: Adding a new server on a fresh install (no servers selected on custom set up)

GUEST: this error was found when nb doesn't contain any server in Tools > Server

GUEST: Add Server

GUEST: I was trying to create a webservice client in my application -> that gave me a incompatibility problem with JDK 6.0 and JAX 2.1 and glassfish.
I installed JDK 6.0 build 12 which seems to have fixed this problem but could not change the default JDK
Changed default jdk by changing the netbeans.conf file
Accidently removed glassfish server from server list.
Now clicking add server button gives me this exception
