Invoke

See Also

The Invoke activity invokes a one-way or request-response operation between the BPEL process and a partner web service on a port provided by the partner. Invoke is used in both synchronous and asynchronous calls. In other words, it enables the BPEL process to exchange messages with partners.

As Invoke interacts with a partner web service, an Invoke activity should be associated with a Partner Link element on the diagram.

To se the Invoke element:

  1. In the Design view, drag the Invoke element from the Palette to the diagram.
  2. Right-click the Invoke element and choose Edit.
  3. In the Property Editor dialog box, configure the following: The Invoke element is now configured to invoke calls to the target partner web service.

Adding Correlation

Correlation sets on Invoke activities are used to verify that outbound messages contain data that is consistent with the data found within specified correlation set instances.

To define correlation use the Correlation Wizard. You can also set the correlation manually.
