Connecting to remote queue instead of local 1

[emerlino]

Hi all,

I'm new with MQ Series and its functionalities.
I write a program that interface with MQ by a java client interface (package com.ibm.mq.*).

My little program runs with no problems when I use a local queue, but have problem (NullPointerException) when trying to use a remote queue.
Such remote queue is defined on the same QueueManager of the right running program.
Have I to specify a different code for remote queue???

Here is some code parts:

// - Inizializzare il Queue Manager e la coda di MQ
String qManager = "QMFX";
MQQueueManager m_qMgr = null;
MQQueue mq_queue = null;
MQMessage sendMsg = null;

try
{
java.util.Hashtable properties = new java.util.Hashtable();

properties.put(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_CLIENT);
properties.put(MQC.HOST_NAME_PROPERTY, "10.100.184.140"
properties.put(MQC.CHANNEL_PROPERTY, "JAVA.CHANNEL"


m_qMgr = new MQQueueManager(qManager, properties);
int openOptions = MQC.MQOO_INPUT_AS_Q_DEF | MQC.MQOO_OUTPUT ;

mq_queue = m_qMgr.accessQueue("UPLOAD", openOptions, "QMFX" , null, null);
}
catch (MQException ex)
{
System.out.println("An MQ error occurred : Completion code " + ex.completionCode + " Reason code " + ex.reasonCode);
out.print("Errore: istanziazione Queue Manager."
}


....

Could somebody tell me why?

Thank's in advance.

Firstly you CANNOT open a remote queue for Input.MQC.MQOO_INPUT_AS_Q_DEF . Secondly where is the remote queue, is the remote queue on the server. Are you running the java app as a client or server app.

Hi mqonnet,

I'll explain you my doing.
I have to run a jsp page under WebSphere that insert a special message into a queue, that has to map this host (the same where running jsp page) and a remote host where I'll get the message out of queue.
I think this is a remote queue.

Well, in writing my basic java/jsp program a had used a local queue to insert and get out my messages.

Can you tell me what is the right option to open a remote queue?

I'll look for "MQC.MQOO_INPUT_AS_Q_DEF" meaning in manuals, since now I've used it without really know what it means!

Thank's for your reply.

Best Regards,

Emilio Merlino.

When you say remote queue, do you mean a queue defined as remote... DEFINE QRMOTE(<>). If yes, then you cannot open remote queues for input which is what is MQOO_INPUT_AS_Q_DEF. Remote queues can only be opened for output to put any messages onto it.
