Hi Mr. Mason,
I really appreciate for your reply, now I get to understand about the
relationship between Tomcat and Apache.
Well~, frankly, I’ve already had a J2EE web application in progress. The
general concept should be like this:
--------------------------------------------------------------
--------------
Web client (user web brower such as IE…) | -------> (Request to tomcat)
----------> | tomcat | (Get and process resources
|
port :8661 | | according to URL
requested
---------------------------------------------------------------
-------------- and return
result HTML to client)
But if I want to add some map features or just a single static web page to show
a map within my website, then
There should be one more architecture:
--------------------------------------------------------------
-------------- Request
-----------------
Web client (user web brower such as IE…) | -------> (Request to apache)
---------> | apache | ---------------> | MapServer |
|
port :8000 | | |
|
---------------------------------------------------------------
--------------
------------------
In another word, our users have to change requesting port number again and
again though accessing a same website, for
They actually send requests to a server (software server) �C tomcat when
requesting dynamic content processed by servlet,
Jsp, whatever, and send requests to another one �C apache when requesting map.
Sir, according to your email, “But being able to script in Java is still a long
way from being able to deploy
to a servlet container like Tomcat.” My personal understanding is there’s no
way for tomcat to replace apache totally
as a middle man role in terms of cooperating with MapServer.
Does that mean we have to keep two web architectures and have
two software servers installed if we want to provide both dynamic content and
map feature?
Or there may be a solution to solve this two-architecture problem?
Thanks for your great help again!!!
Jeff.

Subject: Re: [mapserver-users] Q: MapServer(ms4w) works with tomcat instead of
apache
Hello,
Tomcat and Apache are very different things, and while there is certainly a
degree of overlap in what Apache Httpd and Apache Tomcat can be used for, the
way the two applications actually operate is very different.
Without going in to too much detail here, Tomcat is essentially a J2EE
application container, not a webserver and applications are written using the
Java programming language. You'd normally never use Tomcat to serve files in
the way you'd use Apache httpd. You'd normally delegate such a task to a
webserver. And there really isn't much of an issue about having the two servers
installed, we sorted out the port conflict issues a while back.
Excuse any slight errors here, I've only been using Mapserver a few weeks
myself, but my understanding is that Mapserver essentially a set of C libraries
that are accessible via CGI. You can also access these via PHP, Python and
others even Java it seems, using mapscript. But being able to script in Java is
still a long way from being able to deploy to a servlet container like Tomcat.
If you really want to avoid installing Apache httpd, then you might find
Geoserver useful, as it is a Java web application, and deploying it to Tomcat
is really easy.
But I would recommend trying Apache Httpd, as it's not particularly difficult
to get to grips with.
Hope this helps,
regards
Andrew Mason

Hello,
I’m Jeff from Sichuan, China. I have a question about how to configure
MapServer so that it could be
able to work with apache-tomcat-5.5.26 instead of apache by default. Since I’ve
already had tomcat 5.5.26
installed on my computer and tomcat is well known as both Web server and
application server,
it seems there’s no need to install one more web server �C apache. Furthermore,
more web servers, more
possibilities to conflict, such as listing ports …, right?
Could somebody provide a solution in details on how to achieve this? Thanks!! ~~
Btw, my computer environment:
Windows XP;
JDK 1.4;
apache-tomcat-5.5.26; installed on c:\ apache-tomcat-5.5.26
ms4w_2.2.7.zip downloaded from http://maptools.org/ms4w/ and unzipped to c:\ms4w
Regards,
Jeff.
