Re: [xmlblaster] Unknown log file message

[David R Robison <drrobison at openroadsconsulting.com>]

Sorry for the delay in getting back with you, I was on vacation. To 
answer your question, we are seeing frequent disconnects of the client 
and the service. We are in the process of trying to identify what the 
problem is, but are sure that it is on our side. The messages are being 
sent via a plugin to xmlBlaster and the client subscribes for the 
messages. The client connects as:

   /**
    * Connect to the xmlBlaster.
    *  at param clientUsername the client's username
    *  at param clientPassword the client's password
    */
   public void connect(String clientUsername, String clientPassword) {
       global.init(params);
       xmlBlaster = global.getXmlBlasterAccess();
       connectionState = DGConnectionStates.CONNECTING;
       
DGConnectionManager.getInstance().fireUpdateConnectionState(this, 
connectionState);

       // ConnectQos checks -session.name and -passwd from command line
       ConnectQos qos = null;
       if ((clientUsername != null && !clientUsername.equals("")) && 
(clientPassword != null && !clientPassword.equals(""))) {
           try { qos = new ConnectQos(global, clientUsername, 
clientPassword); } catch (Exception e) { }
       } else {
           try { qos = new ConnectQos(global); } catch (Exception e) { }
       }
       qos.getClientQueueProperty().setMaxEntries(1000); // queue up to 
1000 messages
       qos.getAddress().setDelay(10000L);
       qos.getAddress().setRetries(-1);
       qos.getAddress().setPingInterval(5000L);
       qos.setSessionTimeout(SESSION_LIFETIME_MINUTES * 60 * 1000L); 
//set session to expire in session_timeout_mins minutes.

       // Login to xmlBlaster, register for updates
       xmlBlaster.registerConnectionListener(this);
       try {
           xmlBlaster.connect(qos, this);
       } catch (XmlBlasterException e) {
           log.warn("Error connecting to Data Gateway: " + e);
           reachedPolling(ConnectionStateEnum.UNDEF, xmlBlaster);
       }
   }

I'm not sure if the queue overflowed, I'll have to look deeper into the 
logs. Does this help? Thanks, David Robison
