CCS is:

and servlet is:

package main;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import javax.servlet.RequestDispatcher;
import javax.servlet.ServletConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class registration extends HttpServlet {
	private static final long serialVersionUID = 1L;
	Connection con;
	Statement stmt;
	ResultSet res;
	
	public void init(ServletConfig config) throws ServletException {
		
		try {
			Class.forName("oracle.jdbc.driver.OracleDriver");
			con=DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:ORACLE11","scott","tiger");
		} catch (ClassNotFoundException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
		
	
	}

@Override
	protected void doGet(HttpServletRequest request, HttpServletResponse resp)
			throws ServletException, IOException {
		 resp.setContentType("text/html");
		PrintWriter out=resp.getWriter();
		String name=request.getParameter("name");

What specifically isn't working? What line of JavaScript are you expecting to alert that isn't? Did you look in the JavaScript console in the browser yet? Were there any errors?

Also, note that users can turn off JavaScript in the browser. You really should add validation on the Java side as well.
