This tutorial explains how you can host subdomains with JavaPipe's Java Tomcat hosting. This is assuming that you wish to host a particular webapp for a different subdomain other than your primary domain.
First thing you need to do is to create a subdomain in you SiteWorx control panel. Then you need to add a Host entry in your server.xml (It is a very good idea to back up this server.xml file before editing it.)
Be careful not to change any of the port information - doing so could get your site suspended. Place following code after the last </Host>
tag and just before the </Engine>
closing tag:
<Host name="{sub.primarydomain.com}" debug="0" appBase="webapps"
unpackWARs="true" autoDeploy="true">
<Context path="" docBase="/home/{username}/{primarydomain.com}/tomcat/webapps/{webappname}"
crossContext="false" reloadable="true">
<Valve className="org.apache.catalina.valves.AccessLogValve"
directory="/home/{username}/primarydomain.com}/tomcat/logs"
prefix="{sub.primarydomain.com}_log." suffix=".txt"
pattern="common" resolveHosts="false"/>
</Context>
</Host>
Replace {username}, {primarydomain.com}, {sub.primarydomain.com} and {webappname} with your own.
Set up the webapp or drop in a new WAR file of the new webappname in your webapps directory. Restart tomcat.
