calling MBean example doesn't work

[eddie07]

Hi,

I tried to get the following code (mix of code from the wiki and old examples) to work (first try to use MBEans, so this may be a stupid question):
-----
InitialContext ctx = new InitialContext();
//RMIAdaptor server = (RMIAdaptor) ctx.lookup("jmx/rmi/RMIAdaptor");
MBeanServerConnection server = (MBeanServerConnection) ctx.lookup("jmx/invoker/RMIAdaptor");
// Get the MBeanInfo for the JNDIView MBean
//ObjectName name = new ObjectName("jboss:service=JNDIView");
ObjectName name = new ObjectName("jboss:name=SystemProperties");
MBeanInfo info = server.getMBeanInfo(name);
-----

The getMBeanInfo produces the following exception:
java.lang.NoClassDefFoundError: javax/management/BadStringOperationException

Is there still something I am missing?

Thanks for any help,
Eddie

Sorry for causing trouble, I found the solution. There was only a jar missing in the classpath.
