JSP Write XML

In this section you will study how to generate dynamic XML using JSP.

JSP technology is basically used for building HTML pages with dynamic content but you can use it to generate dynamic content in other formats as well, including XML.

Understand with Example

The Tutorial illustrate an elaborate example on JSP Write XML. To understand the example we make use of java bean that include the string type variables. The java bean can make use of these variables by using setter ( ) and getter ( ) method. The setter ( ) and getter ( ) method are used to define the property of class variable.

set xxx( ) : The set xxx ( ) is used to set the values in variable.

get xxx( ) : The get xxx ( ) is used to access the values from the set xxx ( ) method.

You can see in the given example that we have used xml document in a jsp page and therefore we need to indicate the JSP page compiler by using a JSP page directive tag to set the content type 'text/xml'. The page compiler will use the attributes of the <jsp:useBean> tag to build the Java code to instantiate the bean and populate it with data from the request. The scriplets <% out.print(xml.getId()); %>insert the results into the XML document from the Bean.

Here is the code of GenerateXml.java


package form;

public class GenerateXml{

  private String id = "1";

  private String name = "AAAA";

  private String address="Delhi"; 

  private String contactNo="9999999999"; 

  public void setId(String id) {

  this.id = id;

  }

  public String getId() {

  return this.id;

  }

  public void setName(String name) {

  this.name = name;

  }

  public String getName() {

  return this.name;

  }

  public void setAddress(String address) {

  this.address = address;

  }

  public String getAddress() {

  return this.address;

  }

  public void setContactNo(String contactNo) {

  this.contactNo = contactNo;

  }

  public String getContactNo() {

  return this.contactNo;

  }

}

Here is the code of xml.jsp

<?xml version="1.0" encoding="ISO-8859-1"?>
<%@ page contentType="text/xml;charset=ISO-8859-1" %>
<jsp:useBean id="xml" class="form.GenerateXml"/>
<Company>
<Employee>
<Employee_Id><% out.print(xml.getId()); %></Employee_Id>
<Employee_Name><% out.print(xml.getName()); %></Employee_Name>
<Employee_Address><% out.print(xml.getAddress()); %></Employee_Address>
<ContactNo><% out.print(xml.getContactNo()); %></ContactNo>
</Employee>
</Company>
