I am working in Upgrade project. WAS server getting upgrade to Websphere 6.1, JavaJ2EE application we compiled with IBM JDK1.5.
Now we hosted J2EE application in newly installed WAS 6.1. Client application sending Login request and getting login successfully. If client send next request the session is getting destroyed some session values, So I am getting Null pointer exception.
Can any one say, Is there any settings we need to do in websphere server, or we need to do something in application side.
But it is working fine when we are deploying in TOMCAT 5.5
When it is used for evil, then watch out! When it is used for good, then things are much nicer. Like this tiny ad:
