Session related error

[Nelo Angelo]

Hello,

I am not able to create session for my Servlet. I was initially trying to session the captcha code but found continuous errors with "setAttribute". So I tried a very simple program but still the same error pops ups. Please help.

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

public class program1 extends HttpServlet
{
 public void doPost(HttpServletRequest request, HttpServletResponse response)throws IOException, ServletException
 {
   response.setContentType("text/html");
   PrintWriter out=response.getWriter();

   String name="Jon";
   HttpSession session=request.getSession(true);
   session.setAttribute("Uname",name);
 }
}

With the above code I get the following error:

cannot find symbol
symbol: method setAttribute(java.lang.String,java.lang.String)
location: interface javax.servlet.http.HttpSession

You have a misspelling in line 2.

Line 2 should be import javax.servlet.http.*; I am surprised you did not get a syntax error.

Thanks for the replies, but that's not the problem. I didn't copy paste the code here and its just a typo here. The package name has been written correctly in the code and the same error keeps on showing. I also checked the servlet-api.jar for classes and it contains all that are required. Have checked the environment variables for classpath issues, none found.

Is it possible that my compiler is not functioning correctly? Any suggestions?

[Nelo Angelo]

I hope that everything in the doPost() body is correct.

The compiler specially points out to the setAttribute() method.

Also, if I remove "true" in HttpSession session=request.getSession(true); I get an error something like this:

getSession(boolean) in javax.servlet.http.HttpServletRequest cannot be applied to ().

Where did you get that servlet-api.jar file from? Because if that's correctly part of the class path, it's got wrong versions of classes / interfaces in them if it can't find these methods.
