public class Authentication extends HttpServlet{

  private ServletConfig config;
  
  public void init(ServletConfig config)
    throws ServletException{
     this.config=config;
     }
  public void doPost(HttpServletRequest request, HttpServletResponse response) 
              throws ServletException,IOException{
      
    PrintWriter out = response.getWriter();
    String connectionURL = "jdbc:mysql://localhost:3306/das";
    Connection connection=null;
    ResultSet rs;
    String userName=new String("");
    String passwrd=new String("");
    response.setContentType("text/html");
    try {
       // Load the database driver
      Class.forName("com.mysql.jdbc.Driver");
      // Get a Connection to the database
      connection = DriverManager.getConnection(connectionURL, "root", "root"); 
      //Add the data into the database
      String sql = "select user,password from user";
      Statement s = connection.createStatement();
      s.executeQuery (sql);
      rs = s.getResultSet();
      while (rs.next ()){
        userName=rs.getString("user");
        passwrd=rs.getString("password");
      }
      rs.close ();
      s.close ();
      }catch(Exception e){
      System.out.println("Exception is ;"+e);
      }
      if(userName.equals(request.getParameter("user")) && 
            passwrd.equals(request.getParameter("pass"))){
        out.println("User Authenticated");
      }
      else{
        out.println("You are not an authentic person");
      }
  }
}  

This is ma xml file "web.xml"

   
<!--web.xml code -->
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">

<servlet-class>Authentication</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Authentication</servlet-name>
<url-pattern>/Authentication5</url-pattern>
</servlet-mapping>
</web-app>

I have stored the "Authentication.jsp" and "web.xml" under "JSPMultipleForms" folder, which is under "webapps" folder
The class file stored in the "classes" folder which is under "JSPMultipleForms".

url used for runninng is "http://localhost:8080/JSPMultipleForms/Authentication.jsp" , when i press the "check button" i got these errors

HTTP Status 404 - /JSPMultipleForms/Authentication5

type Status report

message /JSPMultipleForms/Authentication5

description The requested resource (/JSPMultipleForms/Authentication5) is not available.

Apache Tomcat/6.0.20

Please help me how to solve this hurdle....

i got the solution now

"classes" folder and "xml" file stored under "WEB-INF" which is under "JSPMultipleForms"

"Authentication.jsp" stored under "JSPMultipleForms" folder

use the url "http://localhost:8080/JSPMultipleForms/Authentication.jsp"

perfect it's working now .
