Hi all,
I’m trying to achieve following scenario using JMS distributed transactions
with ActiveMQ.
Scenario.
There's are multiple queues and a message needs to be sent to each of these
queue. If at least one of the queues is not reachable, none of the queues
should commit the message.
I found out that we need to add the following parameter axis2.xml to enable
XA Transaction in JMS Transport.
<parameter name="transport.Transactionality" locked="true">jta</parameter>
But when I do, I get the following exception in the console.
[2016-02-26 09:26:51,697] ERROR - ServiceTaskManager Error looking up
UserTransaction : java:comp/UserTransaction using JNDI properties :

I debug the axis2 transport code and found out UserTransaction was
evaluated to null. According to mail thread[1] that is because
"UserTransaction" was not available in the JNDI context axis2 transport was
looking at.
Can some help me to figure out how can I change axis2-transport-jms to make
the "UserTransaction" available for XA transactions?

Thanks.
