Tomcat 4.1.27 not updating servlets

Thread view:

I doing my first J2EE steps using Tomcat 4.1.27
(embeded in JBoss 3.2.2).

I have put my exploded HelloWorld.war (i.e. it's
just a normal directory) that contains a JSP page
and a Servlet into the deploy directory.
I start the server and both JSP page and Servlet
work fine.

There is one thing I do not understand:
When I update the JSP page, I see the result
immediately (on a browser). But when I update
the servlet class file, nothing changes until
I restart Tomcat.

Why is that so? Can Tomcat be configured to
update servlets immediately? Must I really
restart the server? Does Tomcat 5 behave the
same or differently?

Thanx!
Marcus

You can either reload the webapp by clicking the reload link on the manager
page or declare the context in the server.xml and mark it as reloadable.

I think the reloadable feature is not available for auto-deployed
applications.

note that there is a hotfix available to fix a bug with reloading on tomcat
4.1.27

I'm not sure if this same bug is the cause of the OP's problem though

Ah, fine! <http://forums.cookienest.com/viewtopic.php?t=7842>

Which one is better?

Hmm, it seems that I don't have such a file (server.xml)
in my JBoss (3.2.2) installation, where Tomcat is embeded.

thanx!
