Creating a BPEL Process to Access the Master Index Topic

The BPEL process defines the flow of data from the JMS Topic to the external systems that share data with the master index application using the web service definitions you created earlier. The BPEL process created below uses a File binding type. Your process might differ from this based on the binding type you use.

Perform the following steps to create and configure the BPEL process:

• To Create the BPEL Process

• To Create Partner Links

• To Create a Receive Activity

• To Create an Invoke Activity

• To Create an Assign Activity

To Create the BPEL Process

1. Complete the procedure described in Creating a Web Service Definition for the File Binding Component.
2. In the Projects window, right-click the BPEL project, point to New, and then select BPEL Process.

   The New BPEL Process Wizard appears.

3. Enter a file name and location for the BPEL Process, and then click Finish.

   The business process appears in the Business Process Editor.
