This file shows a configuration of 
- a cluster of 4 JOnAS instances running on the same machine,
- a master JOnAS instance to manage the domain, and
- a db JOnAS instance 
The table below lists a possible configuration of all the ports used by those 6 JOnAS instances.
In the following configuration we will deploy the entity beans on node3 and node4.
The Web application is deployed on node1 and node2.

			          __--- Node1 --- Node3 ---__
Apache with mod_jk ---__           x           __--- DB
                        --- Node2 --- Node4 ---

				             Web       Ejb
                          Container  Container

Note :
- You have to activate the AJP Connector (tomcat6-server.xml) for node1 and node2
in order to be able to communicate with the mod_jk module.
Two different ports (for example 9010 and 9011) must be choosen.
Configure the mod_jk to use the 2 instances.
For further information please consult
    http://jonas.objectweb.org/JONAS_5_1_0/doc/doc-en/html/clustering_guide.html
in the section -WEB clustering with Apache/Tomcat -

- Please note that the database used to store the data of the entity beans has to be
the same on both nodes where the ejb's are deployed.
In this example we use the database HSQL mapped to the JNDI name jdbc_1.
We will use the database started by db node, therefore the url defined in
rajdbc.HSQL1.url of build-jc.properties, must be conform to the db.port defined in build-db.properties.
In this example, we have to start the DB node before the node3 and node4.
