Monitor Application

The monitor application shows how to use the ORB's monitor API's for getting values of various JMS server properties. The client simply resolves the jBrokerAdmin object, which has a reference to all monitorable components within a server.

Below is the source code for the Monitor class:

package monitor;
                                                                           
import com.sssw.jbroker.api.admin.Manageable;
import com.sssw.jbroker.api.admin.ManageableCollection;
                                                                           
public class Monitor
{
    private static String iref =
        "corbaloc:iiop:localhost:53506/jBrokerAdmin";
                                                                           
    public static void main(String[] args) throws Exception
    {
    |   if (args.length > 0) iref = args[0];
    |   org.omg.CORBA.ORB orb = org.omg.CORBA.ORB.init(args, null);
    |   ManageableCollection collection = (ManageableCollection)
    |       orb.string_to_object(iref);
    |                                                                      
    |   String[] list = collection.list();
    |                                                                      
    |   for (int i = 0; i < list.length; i++) {
    |   |   System.out.println("*** " + list[i] + " ***");
    |   |                                                                  
    |   |   Manageable manageable = collection.getManageable(list[i]);
    |   |                                                                  
    |   |   String[] propNames = manageable.propertyNames();
    |   |   Object[] propValues = manageable.getProperties(propNames);
    |   |                                                                  
    |   |   for (int j = 0; j < propValues.length; j++)
    |   |       System.out.println(propNames[j] + " = " + propValues[j]);
    |   }
    }
}

The Monitor client locates the manageable collection object and gets the JMSAdmin object. It then invokes the propertyNames method to get all property names. Finally, the getProperties method is invoked to get values of all properties and the result is printed out.
