DO NOT REPLY [Bug 47505] New: Http Session Null issue
https://issues.apache.org/bugzilla/show_bug.cgi?id=47505
Summary: Http Session Null issue
Product: Tomcat 6
Version: 6.0.18
Platform: PC
OS/Version: Windows XP
Status: NEW
Severity: blocker
Priority: P1
Component: Servlet & JSP API
AssignedTo: dev@tomcat.apache.org
ReportedBy: gkiran1980@gmail.com
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:

You absolutely cannot access an (Http)ServletRequest object instance once the
request processing has been completed. That is not allowed.

Hi,
The problem is response object is serving to the browser before creating
context/session object.
I made a change in JSPServletWrapper.java file at line#374 to solve this
problem for temporarily.I know This is not permanent solution,since this a show
stopper for me I made fix like that.
Modified JSPServletWrapper.java file I am attaching to this issue.

You got lucky.
If you do something outside of the specs and it happens to work with one
container, there is no guarantee it will work with any other container.
