Destroying Context Listeners
I recently upgraded my Tomcat installation from 6.0.x to Tomcat 7
(Win64) and I am actively testing our current web applications for
backward compatibility, and so forth. One of these web applications
creates a set of context listeners to manage various things during the
lifecycle of the web application.
During the startup of the web app, I do see that the
contextInitialized() method is called; however when either Tomcat is
stopped or restarted whether from the command line or via MyEclipse 8.6;
I do not see that contextDestroyed() is being invoked. This is causing
some heartburn on our end with this particular web app and I cannot find
any solution.
Has anyone seen this and/or is this confirmed as a problem with Tomcat
7?
Or is there another expectation under Servlet 3.0 that I may have
overlooked.

Pid -
I will download the latest beta and give it a try. When I realized what
was going on, I simply commented out all the logic I had in the two
methods and replaced them with the following:
public void contextDestroyed(ServletContextEvent arg) {
System.out.println("webapp listener context was destroyed.");
log.debug("contextDestroyed invoked successfully.");
}
public void contextInitialized(ServletContextEvent arg) {
System.out.println("webapp listener context was initialized.");
log.debug("contextInitialized invoked successfully.");
}
In my case, I saw the log entries for the initialization, but never for
destroy.
After I update to 7.0.2, I'll retest and let you know.

Try downloading the latest beta, (or compile from trunk).

It might seem like a silly question, but it's not always guaranteed that
someone is using log messages to determine a fault.
Is the log call the very first statement in the method?
What kind of logging is it? If it's a proper logging system and not a
System.out.println call, can you try with the latter instead?

When I check the version of Tomcat 7, it says it is 7.0.0.0.
It's the compiled version from 6/13/2010.
And yes, the log calls in the destroy method are never done, hence my
concern that it isn't being invoked. Under Tomcat 6, these log messages
were captured and written indicating a successful execution of the
method. Even when I use a simple context listener that does a log
message at startup and destroy times, only the startup one is captured.

Which exact version of Tomcat 7.0?
Are you able to consistently reproduce this?
What means are you using to determine that contextDestroyed() is not
called? Log messages or... ?
