Example Illustrating the use of the Textarea<html:textarea> tag.

Here you will learn to use the Struts Html<html:textarea> tag.
We will cover an example that will show a working of<html:textarea> tag.

Example code
Creating Form Bean :
Develop a simple Form Bean class TextAreaActionForm.java.


package ActionForm;



import javax.servlet.http.HttpServletRequest;

import org.apache.struts.action.ActionErrors;

import org.apache.struts.action.ActionMapping;

import org.apache.struts.action.ActionMessage;



public class TextAreaActionForm extends org.apache.struts.action.ActionForm {

    

     private String message;

  

    public String getMessage() {

        return message;

    }

    

    public void setMessage(String string) {

        message = string;

    }

       

    public TextAreaActionForm() {

        super();

  }



}

Creating an Action Class :
Develop a simple action class TextAreaAction.java.

package action; import ActionForm.TextAreaActionForm; 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.ActionMapping; import org.apache.struts.action.ActionForward; public class TextAreaAction extends Action { private final static String SUCCESS = "success"; public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { if(form!=null){ TextAreaActionForm texAreaActionForm=(TextAreaActionForm)form; String message=texAreaActionForm.getMessage(); System.out.println("raj"+message); } return mapping.findForward(SUCCESS); } }

Defining form Bean in struts-config.xml file
Add the following entry in the struts-config.xml file for defining the form bean :

<form-bean name="TextAreaActionForm" type="ActionForm.TextAreaActionForm"/>

Developing the Action Mapping in the struts-config.xml
Here, Action mapping helps to select FormBean and Action etc, from the class for specific requests.

<action input="/" name="TextAreaActionForm" path="/TextAreaAction"     scope="session" type="action.TextAreaAction" validate="false"> <forward name="success" path="/HtmlTextAreaOutPut.jsp"/> </action>�

Developing the HtmlTextAreaTag .jsp page

<%@page contentType="text/html"%> <%@page pageEncoding="UTF-8"%> <%@ taglib uri="http://jakarta.apache.org/struts/tags-bean" prefix="bean" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-html" prefix="html" %> <%@ taglib uri="http://jakarta.apache.org/struts/tags-logic" prefix="logic"%> <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head>     <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">     <th align="right"><font color="#33FF99">HTML:TEXTAREA EXAMPLE</font>     </th><br/>> </head> <body bgcolor="#999933"> <font color="#33FF99">Please Enter the Message------</font><br/> <h4><font color="#33FF99">Message </font><h4><br/> <html:form action="TextAreaAction"> <table border="2"> <td align="left">     <html:textarea property="message"/><br/> </td> </tr> <tr>     <td align="left">         <html:submit/>     </td>     </td> </tr> </table> </html:form> </body> </html>

Developing the HtmlTextAreaOutPut.jsp page :
Add the following line in the index.jsp to call the form.

<a href="HtmlTextAreaTag.jsp">HtmlTextAreaTagDemo</a><br/>�
