10. Performing Data Validation
If you want to customize the content type by changing the constraining facets
applied to the type, see “Customizing a String Content Type” on page 264.
Note: A content type corresponds to a simple type from an XML Schema
definition. All of the choices in the Content type list correspond to simple types
defined in XML Schema Part 2: Datatypes.
e If the selected variable is an Object or Object list, for the Java wrapper type property,
select the Java class for the variable contents. If you do not want to apply a Java
class or if the Java class is not listed, select UNKNOWN.
For more information about supported Java classes for Objects and Object lists,
see “Java Classes for Objects” on page 421.
3 Repeat this procedure for each variable to which you want to apply constraints in the
IS document type, specification, service input, or service output.
4 On the File menu, click Save.
Considerations for Object Constraints
Constraints for Object and Object list variables correspond to Java classes, whereas
constraints for String variables correspond to simple types in XML schemas. When you
apply constraints to Objects and perform validation, the data is validated as being of the
specified Java class. For details on the Java classes you can apply to an Object or Object
list, see “Java Classes for Objects” on page 421.
A constrained Object is validated when one of the following occur:
� A service runs with the Validate input or Validate output check box selected on the
Input/Output tab.
� A service runs via the INVOKE step in a flow service with the Validate input or Validate
output properties set on the INVOKE step.
� The pub.schema:validate service runs.
� A document is published. When this occurs, the contents of the document are
validated against the specified document type. For details, see the Publish-Subscribe
Developer’s Guide.
� During testing, when you enter values for a constrained Object or Object list in the
Input dialog box.
� When you assign a value to an Object or Object list variable on the Pipeline tab using
the Set Value modifier.
