anish pathadan commented on GERONIMO-2880:
------------------------------------------

Hi All,
     The issue is due to geronimo using XA datasource (SystemDatasource) for activemq persistence. I have discussed this issue in activemq forum and I got the recommendation to use a non XA datasource for activemq persistence. The reason is activemq itself is managing the transaction for broker persistence and it doesn't make sense to use XA datasource as there is no other Transaction Manager involved in it.
    I have modified the activemq-broker plan to use NoTxDatasource and I got the issue resolved.I am attaching a patch also.I verified the issue in AG 2.0.1 release.

Thanks,
Anish Pathadan

> I have discovered some problems with queues while running unittest in our own J2EE app.
> After sending a message on a queue, when we try to call the close() method on the queue, we get the following exception:
> ----
> org.apache.activemq.transport.TransportDisposedIOException: Peer (vm://localhost#69) disposed.
> ----
> where the number after "localhost" is different every time.
> We do not experience this problem with topics.  We are using ActiveMQ as part of an "embedded" configuration with Geronimo.
> I've done some debugging and the problem occurs at this line in the ActiveMQMessageProducer.close() method:
> ----
> this.session.asyncSendPacket(info.createRemoveCommand());
> ----
> The queue itself is disposed properly in the dispose() method that is called in the line before, but this sending of the asynchronous packet fails.
