About this task

You must create a message definition file before you can create the message model objects. The message definition file contains the logical and physical model definitions of the objects in XML Schema form.

To create an empty message definition file from scratch:


  1. Switch to the Integration Development perspective.
  2. Open the New Message Definition File wizard.

    To do this, right-click the message set project in the Application Development view that you are adding the message definition file to, and click New> Message Definition File on the pop-up menu.

    The Message Definition File panel of the wizard is displayed. The target message set list is filtered to only show artifacts in the active working set.
  3. Click the message set, type a name into the File name field, and click Next.
  4. Step through the remainder of the wizard, completing the details as required.


The new empty message definition file, with the name that you have specified and a file extension of *.mxsd, opens in the Message Definition editor; you can use the editor to create your own message definitions. If you have chosen to use a target namespace, a directory structure that is based on the URI that you have supplied is created. The new message definition file is placed within this directory structure, which appears in the Application Development view.
