Reqet error, status : 500 Internal Server Error. Message: nu

[brunotonet]

In my web application I am using MyFaces, Trinidad a4j tags and OC4J
server. "ias oracle"

When I am starting my server for the first time my application is
running fine.

After that if I redeploy my application without restarting my server
then I am getting

Reqet error, status : 500 Internal Server Error. Message: null

I am having ajax4jsf problems myself but I know message 500 means it's a server error. What do the logs say?
