Hi friend,


Do check and correct errors in your code and we explain step wise and plz remember it.

-------------------------------------------------------------------------
1.Changes response.sendRedirect("ValidUser") replace with
res.sendRedirect("ValidUser");
-------------------------------------------------------------------------

import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;


public class Slogin extends HttpServlet implements Servlet
{

public void doPost(HttpServletRequest req, HttpServletResponse res)throws IOException, ServletException
{

res.setContentType("html/text");
PrintWriter pw = res.getWriter();

String id = req.getParameter("id");
String pwd = req.getParameter("pwd");

//Redirect call to another url
res.sendRedirect("ValidUser");

}

}
}

///////////////////////////////////////////////////////////////////////////

2.In "ValidUser.java" :

----------------------------------------------------
Changes doPost() replace with doGet() method
----------------------------------------------------

import java.io.*;
import java.io.IOException;
import javax.servlet.*;
import javax.servlet.http.*;


public class ValidUser extends HttpServlet implements Servlet
{

public ValidUser()
{
super();
}

public void doGet(HttpServletRequest request, HttpServletResponse response) throws
ServletException, IOException
{
PrintWriter pw = response.getWriter();
pw.println("Welcome to roseindia.net<br>");
pw.println("how are you");
}
}

//////////////////////////////////////////////////////////////////////////

3 "web.xml"
--------------------------------------------------------------------------
You have not servlet mapping for "ValidUser.java"
--------------------------------------------------------------------------

<web-app>
<servlet-mapping>
<servlet-name>any</servlet-name>
<url-pattern>/Enter</url-pattern>
</servlet-mapping>

<servlet>
<servlet-name>validuser</servlet-name>
<servlet-class>ValidUser</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>validuser</servlet-name>
<url-pattern>/ValidUser</url-pattern>
</servlet-mapping>

</web-app>
