I tried to create a very simple JSF application (targeted to JEE 5, JSF 1.2)
with Web Appliation Wizard in Netbeans 5.5. This process went smoothly until I
was trying to edit web.xml. Netbeans 5.5 sudddenly freezed. As the result, I can
not access to its any GUI widgets. Button: No, Menus: No, Windows: No. All the
GUI was freezed. I tried to turn if off with the cross control at the top right
of the windows: Impossible. All the Netbeans GUI is inaccessible. The last
solution was to open Windows Resourse Manager and kill Java process.

I can open jsp file but I can not access to web.xml file in the folder WEB-INF
from Project Panel without making Netbeans freezed and un-usable. Of course, I
can collapse and extend this folder to browse to the files under it. I can open
and edit face-config.xml and sun-web.xml. But touching web.xml is a disaster.

I have tried to repeat that step for several times and the problem persisted.

I also downloaded the lastest daily builds of Netbeans 5.5 (3rd March build) and
Netbeans 6.0 dev but the problem persisted.

Some exceptions has been throwed after I registered my standalone Glassfish
server with Netbeans. I attached my log file for your reference.

My configuration:

NetBeans 5.5 Dev (Build 200603130300) (Q-build I think, but without Sun
Application Server)
Windows XP version 5.1 running on x86
JDK 1.6.0-beta2-b78; 
Glassfish b42 (installed to standalone and then registered with Netbeans 5.5)
