Message is sendt more than once
Hi.
I have some business logic which process xml from a que served by activemq.
I use receive() to get the xml from the que.
When i run my business logic without the que only one instance of the xml is
receveived, where as when asking to get messages from the que it sends the
same message twice.
at the moment i have set prefect to 1 so only one message should arrive at a
time. This is done via spring.
The weird thing is that when i stop my consumer and watch the webconsole
with the que it says only 1 message is wating to be delivered.When i
activate my consumer , the xml is sendt twice..
Hope you can help me with this.
I run activemq 5.1.0

thanks for all the help, but i am not able to get this working correctly.
The code is like this:
public void start(){
try{
ConnectionFactory factory = getTemplate().getConnectionFactory();
con = factory.createConnection();
con.start();
session =con.createSession(false,Session.AUTO_ACKNOWLEDGE);
MessageConsumer consumer =
session.createConsumer(getTemplate().getDefaultDestination());
while(true){
Message m = consumer.receive();
handleMessage(m);
}
}
catch(JMSException jms){
jms.printStackTrace();
}
}
Could there be anything i am missing?
I have also tried to run with
session_createConsumer(true,Session.SESSION_TRANSACTED).
In my method handleMessage i then tried to do session.comit(), but still no
resolution to this problem.

If you are using transacted sessions then use the SESSION_TRANSACTED
ack mode rather than CLIENT_ACKNOWLEDGED

And does your client acknowledge after it receives it? If not, it will read the message again later since the broker thinks it wasn't received.

Could be an acknowledgment issue, what type of acknowledge (client, auto, dups ok, transaction) are you using?

Hi.
I have some business logic which process xml from a que served by activemq.
I use receive() to get the xml from the que.
When i run my business logic without the que only one instance of the xml is
receveived, where as when asking to get messages from the que it sends the
same message twice.
at the moment i have set prefect to 1 so only one message should arrive at a
time. This is done via spring.
The weird thing is that when i stop my consumer and watch the webconsole
with the que it says only 1 message is wating to be delivered.When i
activate my consumer , the xml is sendt twice..
Hope you can help me with this.
I run activemq 5.1.0
