To add an operation to an existing port type

1. In the WSDL view, right-click the port type node and choose Add -> Operation.

   The Create New Operation dialog box appears.

2. Enter a name for the operation.

3. Select the category of operation.

4. Define the message that the operation receives as input. You can create a message from scratch by entering a new message name in the drop-down list, or you can select an existing message from the drop-down list. For a new message, the Add and Remove buttons enable you to add and remove message parts.

5. If the operation is a request-response operation, then define the message that the operation sends as output.

6. (Optional) If the operation is a request-response operation, then you can define a message that the operation sends as a fault.

7. Click OK.

   An operation node appears. If you created one or more messages, then the message nodes appear.
