the above code is running and working. Now, I want to Connect the application with database. I havethe following code..
HERE:

(ConnectionString.java)

package ojt;

import java.sql.Connection;

public class ConnectionString {
	
	public static String HOST = "jdbc:postgresql://localhost:5432/";
	public static String DB_NAME = "allied";
	public static String USER= "postgres";
	public static String USER_PASSWORD = "admin";
	public static String DRIVER = "org.postgresql.Driver";
	public static Connection con = null;
	
}

(DatabaseManager.java)

package ojt;


import java.sql.*;


public class DatabaseManager{
	
	PreparedStatement stmt = null;
	//Open Connection of Database
	public void openConnection(){
		
		try{
			Class.forName(ConnectionString.DRIVER).newInstance();
		    ConnectionString.con = DriverManager.getConnection(ConnectionString.HOST+ConnectionString.DB_NAME,ConnectionString.USER,ConnectionString.USER_PASSWORD);
		    }catch(Exception e){
		    	e.printStackTrace();
		    	System.out.print("Connection Error!");
		    }
	}
	//Close Connection of Database
	public void closeConnection() throws SQLException{
		
		ConnectionString.con.close();
	}
	
	
	//Add New User
	
	public void addNewUser(String user_code,String last_name,String first_name,String password,String email_id){
		try
		{
			//query to perform
			String query = "Insert into enduser(" +
			"user_code," +
			"lastname," +
			"firstname," +
			"pwd," +
			"email)" +
			"Values(?,;?,?,?,?)";
			
			stmt = ConnectionString.con.prepareStatement(query);
			stmt.setString(1,user_code);
			stmt.setString(2,last_name);
			stmt.setString(3,first_name);
			stmt.setString(4,password);
			stmt.setString(5,email_id);
			
			//execute query
			stmt.executeUpdate();			
			
		}catch(SQLException e){
			e.printStackTrace();
		
		
		}
		
	}
	
}

--------------------------------------------------------------------------------------
Now, here is the servlet that must be called every time the user will press submit button. but I get to have some errors still. I dont know how to fix the error.
But, without using struts i know how to work it out. :(

(RegisterServlet.java)

package ojt;

import java.sql.*;
import java.io.*;

import javax.servlet.ServletException;
import javax.servlet.http.*;




public class RegisterServlet extends javax.servlet.http.HttpServlet implements javax.servlet.Servlet{
static final long serialVersionUID = 1L;


public RegisterServlet(){
	
	super();
	
}

protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException{
	
	
	String user_code = req.getParameter("userCode");
	String first_name = req.getParameter("firstname");
	String last_name = req.getParameter("lastname");
	String email_id = req.getParameter("emailid");
	String password = req.getParameter("pwd");
	
	DatabaseManager dmRegUser = new DatabaseManager();
	dmRegUser.openConnection();
	
	try{
		dmRegUser.addNewUser(user_code,first_name,last_name,email_id,password);
		req.getRequestDispatcher("regSuccess.jsp").forward(req,resp);	
	}catch(Exception e){
		
		e.printStackTrace();
	}
	
	try{
		
		dmRegUser.closeConnection();
		}catch(SQLException e){
			e.printStackTrace();
		}
		
	
}
	
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException{
	doGet(req,resp);
	
}
	
}

I have attached all the required codes.
