By default, if you installed netbeans 6.8, it will have glassfish v3 installed automatically. But there's sometime when you accidentially delete or missing the server, netbeans will asked you to resolve the problem.
By using ordinary method, is impossible to add the glassfish server. It will have blank domainwhere supposed to be filled with domain1 name.
If you're having issues like these, you can solve it by doing following steps
1. Tools > Server
2. Remove the glassfish server from the list and click Close
3.Shutdown Netbeans.
4. Right click on the netbeans icon and click on "Run as administrator"
5. Right click on your web app project and Click on Resolve missing server.
6. Add the Glassfish server again.
In Netbeans 7 this doesn’t work for me. When I try to resolve the missing server problem it doesn’t show the glassfish server.
When reinstalling netbeans and glasshfish it works fine again. But the server keeps getting removed (at random?).
