[jbpm-dev] DataStore impl.

Hi jBPM Users,  I would like to model a BPMN 2.0 Process with DataStores in order to represents persistent inputs (such as files or databases) to task nodes. Suppose we have a task T with datainput I, and suppose we want to bind I to a persistent object representing data, that is, a BPMN 2.0 DataStore D. For instance, suppose that D represents a file, or database. Basically, I would like to represent files or databases inside the BPMN model (with DataStore objects) and use the actual referenced file (or db)  inside the task execution handler. I see jBPM has an object DataStore and that one can set it from the process "Definitions" metadata, but I don't know how to use  this in order to handle files and database from within the task execution handler. Thank you for any support. -- Carlo
