Invoke

BPMN Implementation: Send task, Service task, Rule task, Message throw event

The invoke activity directs a Web service to perform a one-way or request-response operation. It specifies the participant that provides the service and the operation to invoke. The invoke activity must specify the data for the message transmitted and may specify an output variable or variable part in the case of a synchronous request-response Web service invocation. See

Participants

for descriptions of concepts important to this activity.

An invoke activity can be compensated, or reversed. For more information, see

Compensation

An invoke activity can also include fault handling when the invoke is added to a scope. Alternately, any faults associated with the invoked service can be handled at the process level, if desired.

An invoke activity can also include fault handling when the invoke is added to a scope. Alternately, any faults associated with the invoked service can be handled at the process level, if desired. For more information, see

To add an invoke activity to the process manually:

Drag a Send task
(or other BPMN implementation mentioned above) to the Process Editor canvas.

You can add a background color to the send, service, and rule tasks.

In the Properties view, select the following values:

Optionally type in a Name.

In the Participant drop-down, select New Partner Service Provider
. See

Creating a New Partner Service Interface

Select a participant's Operation from the picklist.

In the Input tab, do one of the following:

Select Single Variable from the Assignment Type
and select a variable.

Select a XPaths
or XQuery.
For details, see

From Part to Variable

Optionally, select an output variable
or a to part
. For details, see

From Variable to Part

Select other optional properties as desired.

A simple example of using an invoke activity in a process is shown in the following illustration.

For another shortcut for creating an invoke activity, see
