How to get hostname with jboss_3.2.3

[amedina]

Hi,
is there any way to get the name of the jboss-server in jboss 3.2.3?
This way fails, but works with 4.0.5. I'm starting jboss with the all config, on deployment I get a ClassDefNotFoundException:MBeanServerConnection.

try {
 MBeanServerConnection server = (MBeanServerConnection) new InitialContext().lookup("jmx/rmi/RMIAdaptor");
 ObjectName serverInfo = new ObjectName("jboss.system:type=ServerInfo");
 hostName = (String) server.getAttribute(serverInfo, "HostName");
} catch (Exception e) {
 //...
}

I'm wondering, cause in javaDoc says, that MBeanServerConnection is implemented since 1.5.
