Until now, an operation for sending the request has been defined, but the data that shall be sent has not been defined. This is done by adding (and maybe manipulating the content of) a template to the operation. Therefore, a PETA template should be defined, first. Press the New message template button in the toolbar to open the New Template wizard. Keep the selection on the path peta/template and enter request as the template's name.

Figure 5.7. Create a new template

After pressing the Finish button, the template file will be opened in an XML editor. This template will be a generic description of a client's request. The specific data can be filled in later by the template operation composition or substitution and unneeded parts will be removed by the operation omission.

Enter the following content and save the file:

<request>
    <timestamp>2005-11-11 11:11:11</timestamp>
    <sender></sender>
    <type></type>
    <parameters/>
</request>
