Sessions number issue
Anyone, please throw some insight on the following issue
-----------------------------------------------------
On clicking on the session number '0', he is getting the following error. Any idea?
FAIL - Encountered exception org.apache.jasper.JasperException: Unable to compile class for JSP:

Plus, the OP seems to be disregarding previous hints he's been given, such as
Christopher's earlier post about mismatched installed code versions.
Qadeer Khan, this is a high-quality support list. And on this list we do try to help
people with their Tomcat problems. But one condition is that they also try to help
themselves, and do not just expect answers to be spoon-fed to them.

Seriously, you should try responding to Mark's question here:
http://marc.info/?l=tomcat-user&m=145530442623563&w=2
In general, I went through the archives and read all of the threads.
First, you're not reporting a version of tomcat.
Second, you haven't verified the code is creating sessions by inspecting it.
Third, as asked, you haven't verified that users are even connecting to
the server you're looking at.
You are not going to get a satisfactory outcome. You should really read
this web page:
http://www.catb.org/esr/faqs/smart-questions.html
and re-submit your question from the beginning, supplying all of the
necessary details.
In your particular case, you should document at minimum:
On server A running Apache Tomcat x.x.x, a request to URL ... creates an
incrementing session.
On sever B running Apache Tomcat x.x.x, a request to URL does not create
an incrementing session does not create a new session. I have verified
by inspection of the access logs that the request is going to the
expected web application instance.
If you can do this, you'll probably get more help.

Re: Sessions number issue

And I have no idea what questions I have to answer here! other than application sessions are being created by users and session field is remaining as zero.
On clicking on the session number which is a '0' displays following error message:
An error occurred at line: 109 in the jsp file: /WEB-INF/jsp/sessionsList.jsp
DeltaSession cannot be resolved to a type
106: Session currentSession = (Session) iter.next();
107: String currentSessionId = JspHelper.escapeXml(currentSession.getId());
108: String type;
109: if (currentSession instanceof DeltaSession) {
110: if (((DeltaSession) currentSession).isPrimarySession()) {
111: type = "Primary";
112: } else {

And my questions was why this could be happening and how could this be fixed

Thanks so much for the help. I thought it were the open forum for any one needing support for Tomcat related questions.

What I do not really understand here, is that the (partial) information provided so far
seems to at least indicate that this is a JBOSS site and a RedHat customer; that RedHat
does the development and support of JBOSS and has several JBOSS support forums available;
and that the OP works for RedHat, as a Senior Consultant no less.
So why does the OP not contact his own support resources first ?
I mean, it is not that we don't /want/ to help (Tomcat 6-7 being used by JBOSS and all
that), but would the above not be a logical first step ?

You need to do the research and answer the questions that Mark asked in

Since you're using jboss, this may well be a jboss problem, rather than
tomcat.
