JSP STANDARD ACTIONS jsp:getProperty

                                                               jsp:getProperty

Introduction :

1.    The <jsp:getProperty>  action are used to retrieve data from  the bean as a String object.

2.     You must create or locate a Bean with <jsp:useBean> before you use <jsp:getProperty>.

Limitations:
You can use <jsp:getProperty> with JavaBeans components, but not with enterprise beans. As alternatives, you can write a JSP page that retrieves values from a Bean that in turn retrieves values from an enterprise bean, or you can write a custom tag that retrieves values from an enterprise bean directly.

Example:

getProperty	Getter   methods
<jsp: useBean id= “s” class= “Student”/> <jsp: getProperty name= “s” property= “age”/>	<%       Student s=new Student( );       out. printIn (s.getAge( ));    %>

Attributes:

<jsp: getProperty> tag contains the following 2 attributes

1.    Name :

The name of the bean object from which the required property is obtained.

It is exactly same   as id attribute of  jsp:useBean.

2.    Property : property name of  the  bean class to retrieve .

Test.jsp

<%@ page import = “pack1.*”> <jsp:useBean  id= “s” calss= “pack1.Student”/> Student Name: <jsp: getProperty  name= “s”  property= “name”/> Student Mail   : <jsp: getProperty name= “s” property= “mail”/>

Student.java

package pack1; Public class StudentBean { private String  name= “myjavahub” private String  mail=”myjavahub2012@gmail.com”; public String  getName ( ) {           return name;   } public String getMail ( ) {       return mail;  } }

Output:

Student Name:  myjavahub Student Mail  : myjavahub2012@gmail.com
