Installed NetBeans 5.5 + VWP caused SunAppServer8 stopped working

This is on Mac OS, I have Creator2_1 installed and working well. The bundled SunAppServer8 was also working well before I installed NetBeans5.5+VWP this morning. Then when I tried to deploy projects to it, it says:

java.lang.NullPointerException

at com.sun.rave.dataconnectivity.datasource.DataSourceConfigInfoList.findDriverJar Names(DataSourceConfigInfoList.java:147)

and at the log I found that, it says

javax.naming.NameNotFoundException: No object bound to name java:comp/env/jdbc/xxxx

I don't what has been changed by either NetBeans5.5 or VWP.

Any help is appreciated.
