Every Action Form must have a corresponding validation form.
Extended description
If a Struts Action Form Mapping specifies a form, it must have a validation form defined under the Struts Validator.
Best practices to prevent this CWE
Phase: Implementation
Strategy: Input Validation
Map every Action Form to a corresponding validation form.
An action or a form may perform validation in other ways, but the Struts Validator provides an excellent way to verify that all input receives at least a basic level of validation. Without this approach, it is difficult, and often impossible, to establish with a high level of confidence that all input is validated.
