When ever we complete a task in the jbp process we get the below exception when ever we are using the transaction supports .

If for the completeTask method we specify the TRANSACTION_NOT_SUPPORTED then this works. So in summary the jbpm complete Task fails when used with in transaction.

This is the below exception we get.

Please also refere to theese links , they are also the same issue.
