I want to achieve the following:
i) we have a weblogic queue and external applications would be writing into the queue
ii)I have to write a stand-alone application which can read and write into this queue inside a transaction. i.e. the messages from the queue has to be persisted into DB. So in case of any error at any stage, the transaction should rollback and the message should be available in the queue again.
To achieve this I have done some self study and came across the below URL: http://www.javaworld.com/article/2077963/open-source-tools/distributed-transactions-in-spring--with-and-without-xa.html?page=3 I have understood that I have to use JTA and XA resources for this. I have tried using Atomikos as the JTA Transaction manager following the below URL: http://www.atomikos.com/Documentation/SpringIntegration
After trying whole day I have comeup with the following incomplete applicationContext.xml:

As shown in the Spring-Atomikos integration example, the XAConnectionFactory has been mentioned as :
<bean id="xaFactory"
class="org.apache.activemq.ActiveMQXAConnectionFactory">
<property name="brokerURL" value="tcp://localhost:61616" />
</bean>
I am unable to find the related configuration I need to do for weblogic queue. I have tried using "weblogic.jms.XAConnectionFactory" as the class, but I get classnotfoundexception for that.
I dont have any experience working with JTA or XA. Kindly guide me.
