Show the module positions of a Joomla website

I have been playing with Joomla recently. As a beginner there is a tip that I find useful.
Although it is a tip that is quite well-known (Google brings more than 20 000 results for it), I will still mention it here.
If you want to know the module positions of a Joomla website, add the parameter ?tp=1 to the URL. For instance :

Running 2 JBoss 6.0.0 servers on one machine

Today I wanted to experiment some load balancing with JBoss and Apache. For that I needed to run 2 JBoss servers on one single machine.
Server 1 is installed in D:\jboss-
Server 2 is installed in D:\jboss-

Of course if you run both servers at the same time, you will get errors such as “address already in use” because of services running on the same ports in both servers.
It turns out that you need to modify the D:\jboss-\server\default\conf\bindingservice.beans\META-INF\bindings-jboss-beans.xml file to avoid same port conflicts.
So I added 100 to all ports defined in that file, for server 1.
For server 2, I only modified the HTTP WEB SERVER port because port 8080 is already taken by Oracle.

There is no need to modify the D:\jboss-\server\default\deploy\jbossweb.sar\server.xml file.

Running multiple instances of a single JBoss server is a different story. More information can be found here (ServiceBindingManager) and here .
