Problem getting mbean server

[dhill]

Hi,

I am having problems on some machines with the following code.


List server = MBeanServerFactory.findMBeanServer(null);
MBeanServer beanServer = (MBeanServer) server.get(0);


On some meachines running jboss-4.0.2 on sun jdk 1.4.2_05I get an

ava.lang.IndexOutOfBoundsException: Index: 0, Size: 0
at java.util.ArrayList.RangeCheck(ArrayList.java:507)
at java.util.ArrayList.get(ArrayList.java:324)

Any thought what could be causing this problem.

This link

should help. Perhaps particularly:

import org.jboss.mx.util.MBeanServerLocator;
 ...
// find the local MBeanServer
MBeanServer server = MBeanServerLocator.locateJBoss();

I have tried this method and now that I have time I retested on 4.0.1 vs 4.0.2, it seems something has changed between these 2 implementation, JMX wise that is.

I am running both server on 1.4.2_03 jre. The findMBeaServer works on 4.0.1 but not on 4.0.2.

Any thoughts or suggestions ?
