now ,
in my queue ,there are ten message,
but after i get one message from queue,
the program will throw reasoncode=2033 exception ?
how do i get all message ??
my program is :
MQQueueManager qMgr =new MQQueueManager(qManager);
System.out.println("success connect QueueManager");
int openOptions = MQC.MQOO_INPUT_SHARED | MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_BROWSE;
openOptions=openOptions+MQC.MQOO_BROWSE;
MQGetMessageOptions gmo = new MQGetMessageOptions();
gmo.options=gmo.options+MQC.MQGMO_SYNCPOINT;
gmo.options=gmo.options+MQC.MQGMO_WAIT;
gmo.waitInterval=3000;
MQMessage inMsg=new MQMessage();
while (true){
mqQueue = qMgr.accessQueue(qName,openOptions);
mqQueue.get(inMsg, gmo);
inMsg.clearMessage();
qMgr.commit();
}
catch (MQException ex) {
System.out.println("Error Code2 : " + ex.reasonCode);
ex.printStackTrace();
}
catch(Exception ex){
System.out.println("Error Code1 : " + ex.toString());
ex.printStackTrace();
} |

This is dangerous. The fist statement sets MQC.MQOO_BROWSE, the second removes it and sets another bit? Don't use + and -, use | and & on bit-operations.
Before mqQueue.get(inMsg, gmo); you shoulld set correlationId to MQC.MQCI_NONE and messageId to MQC.MQMI_NONE because every successful get will set this and if you leave this in the object, the next get fails with 2033.

Take a look at Chapter 10 in Application Programming Guide.
There you will find very detailed info about how to get different types of messages from the queue.
