Tomcat, multiple IP addresses, and virtual domains

[david sims <da...@simscomputing.com>]

hi,

Is it possible to configure Tomcat to serve up one set of web pages if
HTTP requests come in to IP address X, and another set of web pages if HTTP
requests come into IP address Y?

What I'm getting at is having a Linux box with multiple IP addresses. I'd like
to configure Tomcat to serve up web pages and servlets for multiple web sites
on the same machine.

I was looking in org.apache.tomcat.service.http.HttpConnectionHandler.java for
some answers, but it's still unclear to me. Hence my post.

If it's currently not possible, I'd be interested in submitting a patch that
does this, as long as someone can guide me a bit on the whole Tomcat
architecture.

And for that matter, I'd be interested in submitting a patch for virtual domain
support. I know the FAQ says "use Apache for virtual domains", but I'm a bit of
a Java bigot. I'd prefer to run Tomcat for everything and not use Apache at all
as a web server.

thanks,
david

I'd be suspect of this. Even if it's tomcat stand alone it's probably a 
really hacked up version of Tomcat (which is ok because that's why 
you got opensource).

I just don't think Tomcat is quite there yet to run stand-alone in 
production. Some might even suggest that we have a ways to go to 
use it as a servlet engine (e.g. stick with JServ for at least a little 
while longer).

There's a lot of things Tomcat doesn't yet support (for example I've 
been hacking on the Security interceptor issue all weekend & still 
without much headway). Or as you've mentioned virtual hosts or 
SSL or have much in the way of documentation (I mean 
opensource is not a stellar example of documentation but Tomcat 
has less than most). Because Tomcat must also support a lot of 
the J2EE reference implementation (at least that was the last word 
I heard at ApacheCon), so in the end it might not be the best 
embedded Web server. 

And if you're doing mostly file-IO stuff, Tomcat is probably not 
going to be the best option (Java IO still blows). Apache is probably 
a better fit.

Tomcat as a stand-alone makes since for certain embedded 
applications or for a case where you have a Java application that 
could benefit from its own Webserver.

I think Tomcat brings a lot to the table. But so does Apache and its 
myriad of modules.

Being a language bigot in the end is very short-sighted. I'm 
extremely fond of Perl, but I hack around with Java because it 
provides some things that Perl doesn't.

oh, I forgot to mention that www.excite.com appears to be running Tomcat as
well. If you go to:

http://www.netcraft.com/whats/?host=www.excite.com

netcraft will tell you that www.excite.com is running Tomcat/2.1. If it's true
that they're running Java Tomcat without Apache, then I *know* that Tomcat would
be fast enough for many, many enterprise applications.

cheers,
david

well, I've got a low volume public web site up now running Tomcat only.
Tomcat's doing a nice job of serving up JSPs, servlets, and static HTML pages
for me. (and the servlets talk to an Enterprise JavaBeans server, but that's
a different story. :-)

It's working so well, in fact, that I don't want to bother with Apache.
Tomcat's doing the job for me. I intend to keep using it as long as I can. And
should I notice some scalability problems with Tomcat later on, I'd much rather
contribute designs and code to the Tomcat project instead of Apache. I want to
help support for Java in the enterprise.

but, to answer your question, I don't know how far Tomcat can scale.

cheers,
david

Can you use tomcat as a standalone webserver for enterprise-level
applications?  I didn't know the standalone webserver could handle that kind
of load.  I thought you had to link apache with it...
