Comment 2 the_patcher 2012-03-05 19:56:46 UTC 
I had the same problem with netbeans 7.1 and 7.1.1 on Windows XP with JDK 1.7.0_03. It looks like it is not possible to add more than one instance of WLS.
The problem might be with the config file: weblogic9.properties in %USER_PROFILE%\.netbeans\7.1\config\Preferences\org\netbeans\modules\j2ee\

Once I deleted this file, I was able to add a new WLS instance, but not a second one. Removing a WLS instance through the netbeans IDE GUI does not removes this file, so to add a new WLS instance, you have to remove this file too.
