Summary: JNDI context problem.
Initial Comment:
I use SUN JDK 1.3.1_01 Server HotSpot VM, Win2K Proff.
Problem exist on next bundles:
JBoss 2.4.3+Tomcat 3.2
JBoss 2.4.3+Tomcat 4.01
JBoss 3.0alpaha+Jetty
Problem:
I put some object into HttpSession. Object implements
HttpSession listener, and should perform some
operation on JNDI context. Everything work fine for
method 'valueBound(HttpSessionBindingEvent event)',
but if I try to work with with JNDI from
method 'valueUnbound(HttpSessionBindingEvent event)',
I've got NameNotFoundException: conext 'env' not bound.
Here is server log:

I mapped JBoss'es java:DefaultDS to
name /jdbc/expound/advisor/AdvisorDS
and /jdbc/expound/advisor/AnalyticsDS in web.xml.
I hope this ENC entries will be enough for test.

Attach the complete war with web.xml that establishes the
ENC entries and I'll look at it under JBoss/Tomcat-4.0.1

In last logs I've got exception, but this happened because
Tomcat has no built in JNDI context.
Will you consider this test, if I setup JNP as default JNDI
for Tomcat 3.2.3. and run test one more time.

BEA and Orion have tightly integrated web containers.
Unless you can demonstrate that Jetty, Tomcat or whatever
servlet container you are embedding in JBoss uses a thread
with the correct class loader, this is not something we
will fix as it requires changes to the internals of the
servlet container.

I test it on BEA weblogic and orion server. This code work
fine. I suspect here is a classloader issue:
Print of Thread.currentThread().getContextClassLoader() for
method valueBound() is here:
org.mortbay.http.ContextLoader(file:/F:/tools/jboss-
3.0.0alpha/deploy/Default/advisor.ear/web1001/WEB-
INF/lib/advisor-client.jar;file:/F:/tools/jboss-
3.0.0alpha/deploy/Default/advisor.ear/web1001/WEB-INF/

INF/lib/jnp-client.jar;file:/F:/tools/jboss-3.0.0a
lpha/deploy/Default/advisor.ear/web1001/WEB-INF/classes/) /
java.net.URLClassLoader@48ef56
and list of classloaders for method valueUnbound() is much
shorter:
java.net.URLClassLoader@48ef56
Do you insist on running this test for standalone tomcat,
or will be satisfied with log file from Orion v1.5.2 ?

It was not a request dispatch thread interacting with a
servlet or JSP page. That is the ONLY thread that has the
correct context for accessing the java:comp/env JNDI
Context. Demonstrate that you can access this context in a
standalone tomcat and I'll considering reopening this.

Yes, you're completly right, I know about threading
restriction in J2EE. BUT IT WAS a tomcat thread(not my
custon), so would you, please so kind, discuss problem
instead closing bug? I bet, you didn't run test(bean&jsp)
even before closing bug.

You cannot interact with the java:comp/env namespace
outside of a thread that invokes methods on the container
component(servlet, EJB). This stack trace shows some
arbitrary thread from tomcat releasing the session
resources. Only the tomcat thread used to invoke a servlet
method can access the java:comp/env of the servlet's web
application.
