Full example of date validator

1) Create index.jsp for input

This jsp page creates a form using struts UI tags. It receives name, password and email id from the user.

index.jsp

 <%@ taglib uri=”/struts-tags” prefix=”s” %>  <s:form action=”register”> <s:textfield name=”dob” label=”Date of Birth”></s:textfield> <s:submit value=”register”></s:submit> </s:form>  

2) Create the action class

This action class inherits the ActionSupport class and overrides the execute method.

RegisterAction.java

 package com.tutoraspire;  import java.util.Date;  import com.opensymphony.xwork2.ActionSupport;  public class Register extends ActionSupport{ private Date dob;   public Date getDob() { return dob; }   public void setDob(Date dob) { this.dob = dob; }   public String execute(){ return “success”; }  }   

3) Create the validation file

Here, we are using bundled validators to perform the validation.

Register-validation.xml

 <?xml version=”1.0″ encoding=”UTF-8″?>    <!DOCTYPE validators PUBLIC    “-//OpenSymphony Group//XWork Validator 1.0.2//EN”    “http://www.opensymphony.com/xwork/xwork-validator-1.0.2.dtd”>    <validators>      <field name=”dob”>   <field-validator type=”date”>   <param name=”min”>01/01/1950</param>   <param name=”max”>01/01/2010</param>      <message>Date of Birth must be between ${min} to ${max}</message>   </field-validator>   </field>         </validators> 

4) Create struts.xml

This xml file defines an extra result by the name input, and an interceptor jsonValidatorWorkflowStack.

struts.xml

5) Create view component

It is the simple jsp file displaying the information of the user.

welcome.jsp

 <%@ taglib uri=”/struts-tags” prefix=”s” %>  Date of Birth:<s:property value=”dob”/>
