Subject Re: Just a few questions on my Tomcat Configuration
Date Wed, 17 Jun 2009 01:41:53 GMT
Just a follow up on this, I did manage to get the virtual hosting and
everything working.

Windows server wise, I used the DNS tools v in Win2K3 Srinstead of the hosts
file.  For some reason the HOSTS file isn't working correctly.  This is an
issue for another time.

What I did to get Tomcat working was pretty much what is in the docs once I
re-re-re-read them.  I used the virtual hosting and it looked like the
problem I was having is that instead of using $CATALINA_HOME/[directory
name]/ROOT, I was leaving the ROOT directory out and putting it into just
the directory name (which coincidentally is how I have it under the webapps
directory -> $CATALINA_HOME/webapps/[software directory])

In my server.xml file, I have narrowed down the <Engine> parameters down to
the base minimum (removed 90% of the comments from the file) and came up
with this:

<Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
      <Host name="localhost"  appBase="webapps"
            unpackWARs="true" autoDeploy="true"
            xmlValidation="false" xmlNamespaceAware="false" />
      <Host name="abc"  appBase="abcapps">
<Host name="abc"  appBase="abcapps">

Notice the absolute basic <Host> parameters, since I don't have a WAR to
deploy, I can get away from all of the extra "hubub" about auto deploy.
However the Alias coincides with the sub-domain that I had set up on
Server2K3.  I've also created an xyz company as well with complete separate
schemas for each of the companies using a custom context.xml in the META-INF
directory to test and it works.  Now I just need to create a script or admin
panel that I can go in and set one up automatically.
