13.     Write code of any Action Class? - Here is the code of Action Class that returns the ActionForward object.
    import javax.servlet.http.HttpServletRequest;
    import javax.servlet.http.HttpServletResponse;
    import org.apache.struts.action.Action;
    import org.apache.struts.action.ActionForm;
    import org.apache.struts.action.ActionForward;
    import org.apache.struts.action.ActionMapping;
    public class TestAction extends Action
    {
        public ActionForward execute(
        ActionMapping mapping,
        ActionForm form,
        HttpServletRequest request,
        HttpServletResponse response) throws Exception
          {
                return mapping.findForward("testAction");
            }
      }

14.      What is ActionForm? - An ActionForm is a JavaBean that extends org.apache.struts.action.ActionForm. ActionForm maintains the session state for web application and the ActionForm object is automatically populated on the server side with data entered from a form on the client side.
  
15.      What is Struts Validator Framework? - Struts Framework provides the functionality to validate the form data. It can be use to validate the data on the users browser as well as on the server side. Struts Framework emits the java scripts and it can be used validate the form data on the client browser. Server side validation of form can be accomplished by sub classing your From Bean with DynaValidatorForm class. The Validator framework was developed by David Winterfeldt as third-party add-on to Struts. Now the Validator framework is a part of Jakarta Commons project and it can be used with or without Struts. The Validator framework comes integrated with the Struts Framework and can be used without doing any extra settings.

16.      Give the Details of XML files used in Validator Framework? - The Validator Framework uses two XML configuration files validator-rules.xml and validation.xml. The validator-rules.xml defines the standard validation routines, these are reusable and used in validation.xml. to define the form specific validations. The validation.xml defines the validations applied to a form bean.

17.      How you will display validation fail errors on jsp page? - The following tag displays all the errors:
<html:errors/>
  
18.    How you will enable front-end validation based on the xml in validation.xml?
- The <html:javascript> tag to allow front-end validation based on the xml in validation.xml. For  example the code: <html:javascript formName="logonForm” dynamicJavascript="true” staticJavascript="true” /> generates the client side java script for the form “logonForm” as defined in the validation.xml file. The <html:javascript> when added in the jsp file generates the client site validation script.
