Hello,
I'm working with an application that uses apache tomcat to serve the
website. I've installed the application and tomcat on a Windows 2003
server and everything is working fine. I do not have Apache or IIS
installed on the server. What I was trying to figure out is how to
make events.mydomain.xxx redirect to the localhost/myapp but without
the localhost part. For instance I want http://events.mydomain.xxx/ to
go to http://events.mydomain.xxx/myapp.

Any ideas how I might do this with apache tomcat would be very helpful
and appreciated. Thank you in advance.

Hi,

Based on what I understood, are you using absolute URLs in your app
instead of relative? If you were refering to root as / instead of
your.app.domain/ the app would have worked fine regardless of the
domain it is installed on. Is this the case?

I'm a bit confused but I'll try to add more info. My app is installed
under the Tomcat root in the webapps/myapp/ directory. When I go to
http://localhost/myapp (on the server) it brings up the homepage. The
app is all preconfigured and I haven't touched tomcat to put in any
URLs or anything. I'm guessing upon install of the app that the folder
for it under tomcat root was created. I'm sorry I'm just not
knowledgable enough in this area. I hope that makes sense. Thanks
again for all the help.

I think all you want is to write an index.jsp, and put that into
tomcat/webapps/ROOT

the JSP can use response.sendRedirect(string) from HttpServletResponse
(which is an implicit variable addressed in a JSP simply as-->
response)

If you want your application to show up as default tomcat app
(localhost instead of locahost/yourapp) , then go to the tomcat's
webapps folder, remove the contents of /ROOT, put your application in
there and give it a try after restarting tomcat. Again - I am not sure
if this is what you want.

if she wanted to go that route, you could instead just edit server.xml
so that

<Host name="events.mydomain.xxx" appBase="">

<Context path="/" docBase="tomcat_home/webapps/myapp" />

</Host>

and thus redefine what is normally the ROOT webapp

I wanted to post back that this did work after a couple of trial and
error situations and remembering that I was working locally and not
publically yet so I had to use .local in the URL when testing instead
of the .com or .edu. Thank you again for all the advice and help.

In Tomcat 6 I used a relative path to make this work:

<Context path="/" docBase="myWebapp"/>

In order to do this the SEO-friendly and correct way so that Google does not identify you as having two different domains -- you need to use a specific HTTP 301 Redirect Code.

The only tricky way I found to do this in Tomcat was to use a Custom 404 Page implementation.

Add a new host entry in $CATALINA_BASE/server.xml as follows

            <Host name="newhost" debug="0" appBase="appbase" unpackWARs="true">
                <Context path="" docBase="docBase" debug="0">
                </Context>
            </Host>

Create a file $CATALINA_BASE/appbase/docBase/WEB-INF/web.xml as follows

<web-app>
    <error-page>
        <error-code>404</error-code>
        <location>/404.jsp</location>
    </error-page>
</web-app>

Create a file $CATALINA_BASE/appbase/docBase/404.jsp as follows

<%
response.setStatus(301);
response.setHeader( "Location", "newbaseURL" + (String)request.getAttribute("javax.servlet.forward.request_uri") );
response.setHeader( "Connection", "close" );
%>
