Developing an Internet Service from a Transaction

Prerequisites

You have created a Web transaction from a task or a workflow, as described in the previous steps.

The Web Application Builder dialog box is displayed: Create Internet Service.

Enter the task ID for the name of the Internet service, select Easy Web transaction, enter the code of the Web transaction generated as the transaction code, and choose Continue.

If you have generated a Web transaction for the workflow WS12345678 and have defined AB as the namepsace template, then the generated web transaction has the transaction code YABWS12345678H. Enter WS12345678 in the Internet service field and YABWS12345678H in the Transaction code field.

Save the Internet service in the same package as the Web transaction.
