JoltTransactionNew Function

Action

Creates a new JoltTransaction object. A JoltTransaction object can be used to include several services into a single transaction. Calling this function implies the beginning of the transaction. When a transaction is timed out, the user must rollback the transaction immediately. Service calls become part of a transaction when the associated transaction object is passed to the service call (see JoltCall function).
