The important differences here from the standard server.xml are the following:
...
| Code Block |
|---|
<Context path="/pluto" crossContext="true" /> |
...
The definition of 'crossContext="true"' is critical here -- this allows the Pluto Portal Driver to make calls into the portlets running inside other webapps.

This should come between the last existing <servlet> declaration and the existing <security-role> declaration.

Then create a file in the conf directory of your Apache installation called 'workers.properties'. This file should contain the following configuration:
| Code Block |
|---|
worker.list=status,loadbalancer worker.status.type=status worker.loadbalancer.type=lb worker.loadbalancer.balanced_workers=tomcatA,tomcatB worker.loadbalancer.sticky_session=1 worker.tomcatA.port=8010 worker.tomcatA.host=localhost worker.tomcatA.type=ajp13 worker.tomcatA.lbfactor=1 worker.tomcatB.port=8011 worker.tomcatB.host=localhost worker.tomcatB.type=ajp13 worker.tomcatB.lbfactor=1 |
With both of your Tomcat instances up and running, restart Apache. Now browse to http://localhost/jkstatus/ and you should see the details about your load balancer and your two Tomcat workers. The tomcatA and tomcatB workers should both have status as 'OK'. If this is not the case, resolve this before proceeding.
This article assumes your Apache is listening on port 80. Modify the URL above and subsequent URL as necessary if a different port number should be used.
