Its basically below:
HttpSession session = request.getSession();
Settings settings = (Settings) session.getAttribute(ATTR_NAME);
I debugged it and got to know that session is getting null and again
invoking the same resource from UI serves fine.
The same is working fine on Weblogic.
Are you sure? The stack trace seems to say that something in
Settings.java, at line 102 is null.
How and when is the object initialised?

Hi,
I am facing strange issue with Tomcat 6 Jsp deployment.
I have JSP pages deployed which internally performs operations and
generates
XML response which will be parsed using XSL and then finally displayed on
the UI.
Now when I invoke JSP pages from UI, session is getting null between the
requests and this works perfectly fine on other Weblogic/Websphere App
servers.
We do use taglibs in xsl and JSPs.
JDK version : 1.5.13
Tomcat Ver: 6.0.18
This error is again random but comes frequently even for the same page 2
times out of 5 clicks.
Any help on this will be useful, thanks.
Posting the error message here for more info:

It's probably not that random.
What is at Settings.java, line 102?
