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?
