I am working on a web application and using JBuilder X as IDE and
Weblogic Server 7.0 as the application server. The problem I am
facing is this:

When I compile and run the application from JBuilder, it works fine
within the JBuilder environment but when i open a seperate browser
window (IE or Netscape), it creates a new session for each request.
My other team mates are using the same environment and their
application seems to work fine either way.

I reinstalled both JBuilder and Weblogic Server but it didn't help.
