2 tips about JBoss

* to retrieve the server name, such as "minimal", "default", "max", in your code

String serverName = System.getProperty( org.jboss.system.server.ServerConfig.SERVER_NAME); 

* to set an unique Xid for each JBoss instance

if you are running multiple JBoss instances on the same machine, you probably want to give each instance a unique Xid base name. To do it, you need to add
the following line in the jboss-service.xml:

<mbean code="org.jboss.tm.XidFactory" name="jboss:service=XidFactory">
    <attribute name="BaseGlobalId">UniqueInstanceName</attribute>
    <!--attribute name="Pad">true</attribute-->
</mbean>
