getNamedDispatcher
Hi, I am trying to use ServletContext.getNamedDispatcher(String) to get
a RequestDispatcher object in my servlet. The goal of this is to
allow my controller servlet to hand off request processing to another
servlet. What I have done is set up a default <servlet-mapping> in my
web.xml file, so that all requests going to the server will be handled
initially by a controller servlet, which will then decide which
servlet should really handle the request. It will go through its
logic and then come up with a string, which will be the real servlet
which will handle the request.
I'm trying to use getNamedDispatcher so that I can avoid the loop that
would happen because of the default servlet-mapping. This seems like
it should work.
In my servlet's init method, I do this:
this.context = getServletConfig().getServletContext();
This works. context is not null after this call, so it definitely
gets a context.
However, later when I do:
RequestDispatcher rd =
this.context.getNamedDispatcher("/static/index.html");
rd comes back as null, and obviously rd.forward(request, response) is
impossible.
Any sugestions on this? How do I get a servlet to send something to a
named servlet without going through the servlet-mappings again?
Thanks

Somebody screwed up the website. I just fixed the Tomcat 4 related links.

How do you get isap_redirect to pass the client certificate to tomcat?
Anyone?
TIA.

tomcat session issue
Posted by Rinku Randhawa <rr...@compunetix.com>.
Hi there,
I am using jakarta-tomcat - 3.2.3 server to run my project. I am finding
that session tracking, when more than one browser window is opened at one
time, doesn't come out to be correct. I am using its inbuilt session object
and the cookies are enabled in my browser. When more than one sessions are
running then the page presented is unpredictable.Sometimes correct page
displays and sometimes totally diferent page gets displayed. It works great
except if I have 2 browsers sessions up - then it gets confused and losses
track of which is the current session.
Are there any issues with the Tomcat server regarding session tracking?
Thanks in advance,
-Rinku

It's more likely to be a problem with your application, or a
misunderstanding of how browsers handle cookies.
In general, cookies are *not* specific to a particular browser window.
Therefore, all windows that the client has open are part of the same
session. This is the way Netscape (at least 4.7.x) always runs -- but in
IIS it's configurable. But the bottom line is that you cannot expect each
window to be running in its own session.

Doing this trick with servlet mappings is pretty much doomed to failure,
as you have discovered, because servlet mappings are applied to the
lookups of request dispatchers as well.
I suggest you look at using Filters (from the servlet 2.3 API) instead.
For instance, you can have a Filter that is mapped to "/*" (and therefore
sees every single request), without disrupting what servlets are mapped to
the various paths. In the Filter, you can make the choice to just pass
the request on, or use a request dispatcher to redirect it somewhere else.
