Debugging BPM 11g Runtime

Question

Hi
I have developed a BPM 11g flow in Jdev 11.1.1.3.0 and deployed it to the soa server.
My flow works fine as my output is sent to a JMS queue and no fault occurs during the flow.
However, if I have to track the Process Data Objects that have been defined, how can i do that?
I am able to track the input/output params on the external service references using composite sensors.
But in my process flow, I have a few process data objects(variables) that are modified,transformed etc before making the service calls.
How will I know what are the values of these modified variables at runtime?
Is there any way to log the process data objects that would help in debugging?
How to set the logging level to debug mode?
Thanks

This may not be the best approach, but I've found it helpful in debugging data values:
You can create a file adapter in your composite.xml, then you can place service call activities in your BPMN process to write out the values to a text/xml file on the server's filesystem.
Choose the "Define operation and schema (specified later)" on the interface screen of the file adapter wizard, operation type as Write file on the next page, choose file location/naming on next page, then on the messages page you click the magnifying glass icon next to the URL field and choose an XSD from your project (associated with a WSDL or a Business Object). When you place the service call to the file adapter in your BPMN process, you then just map in the incoming data object using data associations.
