HttpSessionListener
Hi!
I want to implement an HttpSessionListener. When will the container (Tomcat
5) call the method "sessionDestroyed(HttpSessionEvent se)". Before or after
the session was invalidated (destroyed)? I can't find any documentation
about that detail anywhere.

In the meantime I tested this on Tomcat 5.0.9. But it seems that Tomcat
calls the method after it has invalidated the session. I get an exception:

If I interpret the Servlet 2.4 draft specification right than Tomcat shows a
wrong behaviour. Maybe it's time to open a bug?

In servlet spec version 2.3 the javadoc comments for sessionDestroyed are:
"Notification that a session was invalidated."
It's already invalidated, not always what you want :(
In servlet spec version 2.4 (proposed final draft 3) the javadoc
comments for sessionDestroyed are now:
"Notification that a session is about to be invalidated."
Tomcat 4.x.x implements the former spec, Tomcat 5 will implement the 2.4
spec.

Re: tomcat and virtual hosts

<Host name="www.site1.com" appBase="/export/home/webroot/site1">
....
<Context path="" docBase="/export/home/webroot/site1/ROOT">
....
</Context>
</Host>
Better yet, make the Context docBase = "ROOT" so it is relative to the
Host's appBase.
Put JSP in /export/home/webroot/site1/ROOT. Put WEB-INF in the same
location. Do the same for site 2.

tomcat and virtual hosts
Posted by Johan Louwers <Su...@dds.nl>.
I have set up tomcat and apache... bind them with a JK2 connector both on
port 80. I have 2 domains running on the machine. I made the virtual hosts
work in apache with editting httpd.conf The apache docs are located on the
following location:
/export/home/webroot/site1 (www.site1.com)
/export/home/webroot/site2 (www.site2.com)
I would like to access jsp files on both the website's like
www.site1.com/index.jsp and www.site2.com/index.jsp and store the jsp files
at the same location as the html docs. This means locate them in
/export/home/webroot/site1 and /export/home/webroot/site2
How do I make tomcat understeand that it must be running jsp files on this
locations. Anybody knows how to do this? You have to add some things to
server.xml i know that buth what and do have to edit httpd.conf in some way
to make this work? A working example of a server.xml/httpd.conf file is
welcome and also any tip hint and clue :-)
Thanks already,
Johan.
