Using the Validate Element

The Validate element is used to validate the values of variables against their associated XML and WSDL data definition. The element includes a Variables property that lists the variables for the process, and allows you to specify which variables to validate. When one or more variables prove invalid against a corresponding XML definition, a standard fault, bpel:invalidVariables, is thrown.

Usage

Drag and drop the Validate element to the diagram between Process Start and Process End. From the Validate Properties, click the Variables edit button. Select the variables you want validated from the Variables dialog box.

Validate Element Properties

The Properties window of the Validate element, accessed by right-clicking the element and choosing Properties, contains the following properties:

• Name: The name of the element.

• Documentation: User documentation attached to the element. This documentation is included with the source code of the BPEL process and can be extracted and included in a report.

• Variables: Specifies the variables for the process, and allows you to select which variables to validate.
