Subject hurry!why the consumer receiver the same message more than once
Date Sun, 03 Sep 2006 09:30:53 GMT

hi, 

   i use activemq for messageque,recently i found that the cunsumer can
receive the same message many times for a peried time. 

  why it happened 

   the message i received is 

  ActiveMQTextMessage {commandId = 29405, responseRequired = false,
messageId = ID:ibm-9d2a79eb7cc-1989-1157269673140-1:1:7351:1:1,
originalDestination = null, originalTransactionId = null, producerId =
ID:ibm-9d2a79eb7cc-1989-1157269673140-1:1:7351:1, destination =
queue://TEST.FOO, transactionId = null, expiration = 0, timestamp =
1157269455978, arrival = 0, correlationId = null, replyTo = null, persistent
= false, type = null, priority = 4, groupID = null, groupSequence = 0,
targetConsumerId = null, compressed = false, userID = null, content =
org.apache.activeio.packet.ByteSequence@12d15a9, marshalledProperties =
null, dataStructure = null, redeliveryCounter = 34, size = 0, properties =
null, readOnlyProperties = true, readOnlyBody = true, text = null} 



    is anyone can tell me why the same message can by received more than
once 

   and how can i avoid the problem 


   many thanks
