BPEL Interaction Pattern - Using JMS as the medium

Question

Objective : Make one MAIN Business Process out of BPEL that would receive the Message from Userinput or some other source and finally after doing all operations inside BPEL process (that would happen using BPEL Sub processes that exchange data using JMS send and receive inside the different queues ). Finally the MAIN Business Process would receive the response from BPEL sub process send it to Database at the end. We would like to develop a single BPEL process that would represent a Business Process say like Order Create and internally we would invoke various Sub BPEL process to work on the payload and give a handshake using JMS as the medium rather than another BPEL process makes a direct handshake to the invoking/calling process.
Steps Attempted :
a) BPEL Process receives the message from Input (User input of Purchase Order) and do some transformation later publish the message to Queue by configuring JMS Adapter to Produce it. Next step inside the same BPEL process tries to receive it using the JMS Adapter to consume it. It keeps waiting forever without consuming the message
b) BPEL Process (A) receives the message from (User input of Purchase Order) and do some transformation later send the message to another BPEL Process (B) that would receive the input message. BPEL Process B writes into the Queue using JMS Adapter. In this case also BPEL Process (A) configured to receive the message from the QUEUE where the BPEL PRocess B has sent. BPEL Process A waits for the message to arrive for ever.
Some behaviours we noticed ,
1) Queue messages are being dequeued (JMX Browser in OEM shows no messages). But BPEL console shows the BPEL Process A is waiting for it to arrive. I believe it is consuming the message but unable to kickoff from receive (JMS activity) activity configured in the BPEL.
2) We ensured that no other BPEL Process is consuming by creating a new Queue by name DemoQueue4 that would be used by the BPELProcess A and BPEL Process B.
3) BPEL Process A and BPEL Process B are ASYNCHRONOUS Process. BPEL Process B receives the input and writes into the Queue does not call back to BPEL Process A. BPEL Process A would listen to the Queue to receive it inside the BPEL Process A.
Am I trying something architecturally not possible ?
Thanks

You can register any compliant JMS provider as a foreign jms provider in weblogic and then can access the JMS administered objects (destination and connection factory) from the local weblogic JNDI tree.
This blog shows how to configure AQJMS as a foreign JMS provider and then configure JMS adapter to access the jms objects.
http://biemond.blogspot.com/2009/07/using-aq-jms-text-message-in-wls-1031.html
You can use the above link as a reference on how to setup. You will have to modify the Initial Context Factory, Provider URL, JNDI Properties, foregin connection factories and foreign detsinations section to suit activeMQ.
Note: Weblogic does not come inbuild with the required jars to connect to ActiveMQ unlike AQJMS, so you need to ensure that the active mq jms client jars are available in the weblogic's classpath.
