Hi Friend,
Try the following code:
1)Person.java:
public class Person {
private String name;
private String email;
private long phoneNo;
public Person() {
setName("Tom Hawk");
setEmail("tom.hawk@gmail.com");
setPhoneNo(1213);
}
public void setName(String name) {
this.name = name;
}
public String getName() {
return name;
}
public void setEmail(String email) {
this.email = email;
}
public String getEmail() {
return email;
}
public void setPhoneNo(long phoneNo) {
this.phoneNo = phoneNo;
}
public long getPhoneNo() {
return phoneNo;
}
}
2)BeanInServlet.java:
import java.io.IOException;
import javax.servlet.RequestDispatcher;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
public class BeanInServlet extends HttpServlet {
protected void doGet(HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException
{
Person p = new Person();
p.setName("Sam Dalton");
p.setEmail("sam2222@gmail.com");
p.setPhoneNo(1111111111);
req.setAttribute("person", p);
RequestDispatcher rd = req.getRequestDispatcher("/jsp/beandata.jsp");
rd.forward(req, res);
}
}
3)beandata.jsp:
<html>
<body>
<table>
<tr><td>Name is:</td><td>${person.name}</td></tr>
<tr><td>Email is:</td><td>${person.email}</td></tr>
<tr><td>PhoneNo is:</td><td>${person.phoneNo}</td></tr>
</table>
</body>
</html>
4)web.xml:
<servlet>
<servlet-name>BeanInServlet</servlet-name>
<servlet-class>BeanInServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>BeanInServlet</servlet-name>
<url-pattern>/BeanInServlet</url-pattern>
</servlet-mapping>
Thanks
