Run the MakeCheckAppt Web Service

Walks you through the process of creating a debug configuration for your new service, and running the client application to access and debug the service.
Restriction: This topic applies to Windows environments (local development) only.

Create a Debug Configuration

  1. In the Team Developer Tree View, click the ProgramSOAP project.
  2. From the main menu, click Run > Debug Configurations.
  3. In the left pane, right-click COBOL Enterprise Server; then select New from the context menu.
  4. At the very top of the right pane, type ProgramSOAP into the Name field.
  5. On the General tab click the Browse button that corresponds to the Connection and Server fields.
  6. Select ESSOAP; then click OK.
    Note: If the ESSOAP enterprise server instance is the only instance defined in Enterprise Server, these fields are completed for you.
  7. Under Debugging type, click the Web Service tab.

    This shows that all debug Web services are invoked by a request from the client.

  8. Click Apply; then click Debug.
  9. Answer Yes to any prompts to open views or perspectives.
  10. In the Debug view, you should now see an entry for debugging ProgramSOAP [COBOL Enterprise Server].

Set Breakpoints

You want to be able to see when the client program hands off control to the service running in Enterprise Server. Because the program hands off control at two points in its execution – first to run the MakeAppt operation, and second to run the CheckAppt operation – you set a breakpoint at each hand-off point in the code so you can step through the program.

The code that calls the service is contained in the MakeCheckAppt-proxy.cbl file:

call "InvokeService02"

It appears twice in the program. You want to set a breakpoint just before each of these call statements.

  1. From the Team Developer Tree View, expand ProgramSOAP > client.
  2. Double-click MakeCheckAppt-proxy.cbl. This places the source code into the COBOL editor.
  3. Press Ctrl+F to search for the following code:
    move 256 to wsc-srvc-faultcode-len
  4. Place your mouse pointer in the left-most column at that line of code and double-click to set a breakpoint.
    Note: When the breakpoint has been set, a dot appears in the left-most column.
  5. Search for the next instance of:
    move 256 to wsc-srvc-faultcode-len
    and set another breakpoint.

Run the COBOL Client

  1. From the Team Developer Tree View, expand ProgramSOAP > client.
  2. Right-click MakeCheckAppt-app.cbl; then select Debug As > COBOL Application from the context menu.
    Note: If a Confirm Perspective Switch message appears, click Yes.

    This places an entry into the Debug view for the client application.

  3. In the Debug view, right-click the bottom-most entry; then select Resume.
  4. The client invokes a console named runm, and waits for input. In the runm console, complete the fields as follows to set an appointment slot:
    Service Address leave blank
    Username leave blank
    Password leave blank
    Operation 1
    lnk_customer_name Benton Riley
    lnk_consultant_id 8706
    lnk_date.lnk_yyyy 2525
    lnk_date.lnk_mm 1
    lnk_date.lnk_dd 1
    lnk_time_slot 5

    The client application then resumes execution, and pauses on the move 256 to wsc-srvc-faultcode-len statement.

  5. Switch back to the Debug view.
  6. Press F6 multiple times to step through the code until you have stepped just past the call "InvokeService02" statement.
  7. On the Debug view, expand entries under all COBOL Thread entries. You should see that the deployed schedule application is now being accessed from Enterprise Server.
  8. Press F8 to resume and terminate execution.

Rerun the COBOL Client

Here you rerun the client, selecting the other operation to see that the appointment has been made.

  1. In the Debug view, right-click the MakeCheckAppt-app.dll entry marked as <terminated>; then select Relaunch from the context menu.
  2. In the Debug view, right-click the bottom-most entry; then select Resume.
  3. Complete the runm fields as follows:
    Service Address leave blank
    Username leave blank
    Password leave blank
    Operation 2
    lnk_customer_name Benton Riley
    lnk_consultant_id 8706
    lnk_date.lnk_yyyy 2525
    lnk_date.lnk_mm 1
    lnk_date.lnk_dd 1

    The client application then resumes execution, and pauses on the move 256 to wsc-srvc-faultcode-len statement.

  4. Press F6 multiple times to step through the code until the appointment you set appears on the list in the runm client. You should see it on line [00005] because it is the fifth appointment set for that day.
  5. From the Debug view, press F8 to resume and terminate execution.
