I have written hibernate code for insert and delete in database but in insert button , delete function are executing My code has given below
package registration;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;
import org.hibernate.Transaction ;

@WebServlet(name = "RegistrationServlet", urlPatterns = {"/rs"})
public class RegistrationServlet extends HttpServlet {



@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// doPost();
// processRequest(request, response);
}


@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// processRequest(request, response);


// response.setContentType("text/html;charset=UTF-8");
//PrintWriter out = response.getWriter();
String name= request.getParameter("name");
String email= request.getParameter("email");
String password= request.getParameter("password");

SessionFactory sessionFactory=new Configuration().configure().buildSessionFactory();
//SessionFactory sessionFactory1=new Configuration().configure().buildSessionFactory();


if(request.getParameter("delete")!=null);

{


Session sessionDelete=sessionFactory.openSession();
deleteData(email,sessionDelete);



}
if (request.getParameter("submit")!=null )
{


Session session=sessionFactory.openSession();
insertData(name,email,password,session);





}
/* try {
/* TODO output your page here. You may use following sample code. */
/* out.println("<html>");
out.println("<head>");
out.println("<title>Servlet RegistrationServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet RegistrationServlet at " + request.getContextPath() + "</h1>");
out.println("</body>");
out.println("</html>");
}
finally
{
out.close();
*/


}
public void insertData(String name, String email, String password, Session sessionInsert)
{

Transaction transactionInsert= sessionInsert.beginTransaction();
Rgdata rgdata=new Rgdata();
rgdata.setName(name);
rgdata.setEmail(email);
rgdata.setPassword(password);
sessionInsert.save(rgdata);

transactionInsert.commit();
sessionInsert.close();

}


public void deleteData(String email,Session sessionDelete)
{

Transaction transactionDelete=sessionDelete.beginTransaction();
Rgdata updateRgdata=(Rgdata) sessionDelete.get(Rgdata.class,email);
//updateRgdata.setName();
//session.update(updateRgdata);
sessionDelete.delete(updateRgdata);
transactionDelete.commit();
sessionDelete.close();

}

}
