Tomcat – Redirecting URL to different web app in Tomcat

tomcat

I am running tomcat 6.0, and am having trouble configuring it to do what I want…

I have two web apps, call them X and Y, deployed as X.war and Y.war. Each has a servlet called blah.

So I can access them like so:
http://server/X/blah
http://server/Y/blah

What I want to do is pretend they are one web application Z, and be able to do this:

http://server/Z/X/blah –> as if I'd gone to http://server/X/blah

http://server/Z/Y/blah –> as if I'd gone to http://server/Y/blah

So I changed the (catalina_home)/conf/Catalina/localhost/X.xml as follows:
< context override="true" path="/Z/X" reloadable="false" >

However that didn't work out; when going to http://server/Z/X/blah I get "The requested resource (/Z/X/blah) is not available."

Where am I going wrong?

An alternate way to do this would be to setup tomcat behind apache via ajp. Then, use mod_proxy_ajp to map the http://server/Z/ to ajp://server/ instead.

Centos – Tomcat with virtual hosts – 404

It smells like maybe it's running into a mod_rewrite or alias before it's getting to your virtual host definition. Everything you've posted looks correct, but you can try adding a few extra options:

JkWorkersFile  /explicit/path/to/workers.properties
JkLogFile      /var/log/mod_jk.log
JkLogLevel     debug

That first setting will make sure you're using the actual properties file you think you are, maybe something in your multi-tomcat environment is loading the wrong one. You might also check this specific instance's TOMCAT_HOME to ensure it's loading the right server.xml; you can actually pass that as well as a parameter to $TOMCAT_HOME with -config:

cd $TOMCAT_HOME
./bin/startup.sh -config /direct/path/to/server.xml

Tomcat – Adobe Coldfusion Railo OpenBD Apache Tomcat Multiple Sites

You generally want your Tomcat Host's appbase="webapps" (default) and have the Context's docBase point to your Web root (docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"). Your Web root will contain a WEB-INF for whichever WAR you're using (ColdFusion/OpenBD/Railo). It sounds like you're using a symlink or something for the WEB-INF dir?

In any case, you can't run requests against 3 different WARs in the same Web root (at least not without some fancy connector stuff--you could let a JRun instance/connector run while having WEB-INF of Railo or OpenBD in the Web root to then use 2 different Apache vhosts to handle... but this all sounds messy:). So, since you can't run them at the same time with this setup, I'm not sure why you're using separate host names?

It's also worth noting that you'll likely need to restart the Tomcat service each time you replace (re-map symlink) the WEB-INF folder.

Finally, if you do have the same Web root (docBase) for all three Tomcat Host entries, I'd imagine this will most certainly cause problems -- this could be the root of your errors, but not sure. Since you want the same Web root for each host, you might as well use an Alias (or just one host), something like this:

<Host name="local.mydev" appBase="webapps">
<Alias>local.mydev.railo</Alias>
<Alias>local.mydev.openbd</Alias>
<Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot" />
</Host>
