BPMN 2 Service Tasks

[ayman]

in Version 11:
how to Add/Define a Pool Package to be selected in Service Tasks?

[MMA]

Sorry I didn't get the question.

If you have a BPMN Specification(http://www.omg.org/spec/BPMN/index.htm), refer to Figure 10.12, the Service Task inherits the attributes and model associations of Activity and presents following additional association and attributes:
    implementation: string = ##webService
    operationRef: Operation [0..1]


A pool is the representation of a participant, which can reference to a process that contains elements like event, task (e.g. a ServiceTask) etc...

Hope this helps
