Step 1: Extract the Interface of a COBOL Server

Follow the instructions for extracting COBOL, see Using the IDL Extractor for COBOL - Overview and choose Scenario I: Create New IDL and SVM if this is your first extraction.
This process creates the following EntireX metafiles:

Step 2: Generate the Connection and Adapter Services in Integration Server

This step is described in more detail under Using the Integration Server Wrapper.

Select the IDL file, and from the context menu choose Generate webMethods Connection from IDL file.... From the wizard, select an Integration Server instance and select the connection type.

Then select the namespace where you want to write the services to, and specify the connection properties.

Step 3: Execute the Call from Integration Server to COBOL

From the Service Development perspective, refresh the package where the connection service was written, select the Adapter service, and use the service test to Run Service:
