The class HttpSessionBindingEvent exists in the javax.servlet.http package. Its event are sent to an object that implements the HttpSessionListener when it need to bound or unbound a session.

Code:

package roseindia.servletexample;

import javax.servlet.http.*;
import javax.servlet.ServletException;
import java.io.IOException;
import java.io.PrintWriter;

public class HttpSessionBindingEventExample extends HttpServlet {

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {

PrintWriter out = response.getWriter();

HttpSession session = request.getSession(true);
HttpSessionBindingEvent bind = null;
bind = new HttpSessionBindingEvent(session, "sessionbinding");

if (bind != null) {
out.println("sesion binding sucessfully ");

} else {
out.println("sesion binding failed");

}
}
}

The result is conditional one when the variable bind is holding the name of the object that has been bound to or unbound from a session. If the variable hold some some value it will display "session binding sucessfully" else "sesion binding failed".
