Using JMX a read list of user names

[hildo]

I'm designing an EJB application which, for one point, allows a user to assign a task to a system user. I'd like to provide a list of known system users to the client.

Given that the Container is in charge of defining system users, I'd like to be able to use the JMX objects to retrieve a list of valid system users (whose String name value would be used in the assignment logic).

Is there an example of how to access the JMX code from within the EJB Application to access this data?

Thanks,
Ed

Why don't you get the MBean to bind the list
into JNDI?

I'm very open to suggestions. I didn't know if I was able to (from within the EJB application) access the JMX beans directly. I'm assuming that however I access the data at runtime, I'm using JNDI to get the list. But I was after the mechanisms to get at the JXM code. I was hoping that I could use it directly, so I didn't have to worry about maintaining my own list separate from the container's list.

MBeanServer server = (MBeanServer) MBeanServerFactory.findMBeanServer(null).get(0);
List list = (List) server.getAttribute(yourObjectName, "YourAttribute");

Thanks Adrian. I'll store this away and give it a try when I get to development. :)

Thanks again,
