The required field validator in Struts can be used to check if field is non-null. It can be used in either of the following forms:

• • XML: using type=”required” attribute in <validator> or <field-validator> elements.
  • Annotation: using @RequiredFieldValidator annotation type to annotate setter method of the field or action method (plain-validator).

One example usage of this validator is to validate a field whose value is pulled from a dropdown list which may contain no items (the items are generated dynamically).

ResetToken - reset the token key Example: Step 1. Action Class where saveToken before JSP Page. First saveToken then forward to your jsp. Upon loading the form, invokes saveToken on the action class to create and store the token key. Struts will store the generated key in request/session. Sets whether or not to generate the dynamic JavaScript. Void: setFormName(java.lang.String formName) Sets the key (form name) that will be used to retrieve a set of validation rules to be performed on the bean passed in for validation. Void: setHtmlComment(java.lang.String htmlComment) Sets whether or not to delimit the JavaScript with html comments.
