You can use different Servlet or same servlet .
But as if you find some information about MVC it is said that Servlet should be made as controller and how it is made is by using only single servlet and giving wildcard mapping for servlet .
One of the topic may help you is https://coderanch.com/t/359118/Servlets/java/Wildcard-servlet-mappings-web-xml OR you can also search for the wildcard mapping for servlet .

Hi,

I have a login page where user information is collected passed to the servlet where it is connected to DAO class where it validates the email received with the database.If emails are different it will provide new userid for that user sends it to register.jsp.Now the user enters the password and all the in formation should be stored in the database.How to connect to the servlet now? Is the same servlet we have to use( if so how and what method we have to use?)If different servlet how it is?I am using MVC architecture.
Please suggest me.

Thank you.
I have two beans namely employee and department.This is one-to-many relationship where in one department many employees are working.department_id is the primary key.
when i run this it asks "select a java application" giving some options like SchemaUpdate,DBdialect....If i choice any one it shows so many exceptions.Wher i have gone wrong?One difference is in configuration file i have given <property name="hbm2ddl.auto">create</property>

This is Runner class which has main method

This is Runner class which has main method

package Manytoone;

import org.hibernate.HibernateException;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;

public class Runner {

static void main(String[] args) {
SessionFactory factory=FactoryOneInstance.getInstance();
Session session=factory.openSession();
Transaction trans=session.beginTransaction();
Employee employee=new Employee();
Department dept=new Department();
employee.setName("Kavitha");
dept.setName("Software");
dept.setEmployee(employee);

try
{
trans.begin();
session.save("dept",dept);
trans.commit();
}
catch(HibernateException e)
{
e.printStackTrace();
trans.rollback();
}

}

}

This is employee.hbm.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE hibernate-mapping PUBLIC
