Websphere 7 SIB Queue: how to access queue depth from Java?

Question

I've created some code to access queue depths for a Websphere MQ, but I can't work out if there is an API for accessing a SIB queue, or if I can setup websphere to allow me to access it.

Can anyone give me some hints/ideas?

Thanks Jeff Porter

The answer, for those that care is SOAP.

Ok, so I've not managed to get the API used by WSADMIN to work, but I've used SOAP direct into websphere to ask it about the queues.

Note: Default port is 8880

 Properties connectProps = new Properties();
 connectProps.setProperty(AdminClient.CONNECTOR_TYPE, AdminClient.CONNECTOR_TYPE_SOAP);
 connectProps.setProperty(AdminClient.CONNECTOR_HOST, "127.0.0.1");
 connectProps.setProperty(AdminClient.CONNECTOR_PORT, "8880"); 

 AdminClient adminClient = null;
    try
    {
      adminClient = AdminClientFactory.createAdminClient(connectProps);

      Set<ObjectName> s2 = adminClient.queryNames(new ObjectName("WebSphere:*"), null);
      if (!s2.isEmpty())
      {
        Iterator<ObjectName> i = s2.iterator();
        while (i.hasNext())
        {
          ObjectName on = i.next();
          String type = on.getKeyProperty("type");
          if ("SIBQueuePoint".equals(type))
          {
            String queueName = on.getKeyProperty("name") ;
            int currentDepth =  ((Integer) adminClient.getAttribute(on, "depth")).intValue();
            int maxSize =  ((Integer) adminClient.getAttribute(on, "highMessageThreshold")).intValue();

            LOG.info("Queried SIB queue: Queue: [" + queueName + "] Size =[" + currentDepth + "] highMessageThreshold:["+maxSize+"]");
          }
        }
      }
      else {
        System.out.println("MBean was not found");
      }
    }
    catch (Exception e)
    {
      LOG.error("Error finding SIB queue details, message:" + e.getMessage(), e); 
    }
