As before, we set everything up in four steps: create the form, create the action, register the action, and create the landing page (or in this case, pages).

1. Create the form

Wiki MarkupPaste this html into \[ webapp\]/page03.jsp:

Code Block
html
html
<html>
<head>
	<title>A simple form with data</title>
</head>
<body>
	<p>What is your name?</p>

	<form action="form03.action" method="post">
		<p><input type="text" name="yourName"></p>
		<p><input type="submit" value="Submit your name." /></p>
	</form>

</body>
</html>

2. Create the form action

...

Paste this code into \[ src\]/lessons/Form03Action.java:

Code Block
java
java
package lessons;

import com.opensymphony.xwork.ActionSupport;

public class Form03Action extends ActionSupport {

  String yourName;

  public void setYourName(String p_yourName) {
    yourName = p_yourName;
  }

  public String getYourName() {
    return yourName;
  }


  public String execute() throws Exception {
    if (yourName == null || yourName.length() == 0)
      return ERROR;
    else
      return SUCCESS;
  }

}

3. Register the action in xwork.xml:

Wiki MarkupEdit \[ webapp\]/WEB-INF/classes/xwork.xml:

Code Block
xml
xml
<!DOCTYPE xwork PUBLIC "-//OpenSymphony Group//XWork 1.0//EN"
 "http://www.opensymphony.com/xwork/xwork-1.0.dtd">

<xwork>
  <!-- Include webwork defaults (from WebWork JAR). -->
  <include file="webwork-default.xml" />
  
  <!-- Configuration for the default package. -->
  <package name="default" extends="webwork-default">
    <!-- Default interceptor stack. --> 
    <default-interceptor-ref name="defaultStack" /> 
    
    <!-- 02 --> 
    <action name="form02" class="lessons.Form02Action"> 
      <result name="success" type="dispatcher">page02-success.jsp</result> 
    </action> 

    <!-- 03 -->
    <action name="form03" class="lessons.Form03Action">
      <result name="success" type="dispatcher">page03-success.jsp</result>
      <result name="error" type="dispatcher">page03-error.jsp</result>
    </action>

  </package>
</xwork>

4. Create the success and error pages

...

Create \[ webapp\]/page03-success.jsp:

Code Block
html
html
<%@ taglib uri="webwork" prefix="ww" %>
<html>
<head>
	<title>Success page for form with data</title>
</head>
<body>

Hello, <ww:property value="yourName" />!

</body>
</html>

Wiki MarkupCreate \[ webapp\]/page03-error.jsp:

Code Block
html
html
<html>
<head>
	<title>Error page for form with data</title>
</head>
<body>

</body>
</html>
