Hi all:
I am getting the following error when trying to access a servlet:
Error: 500
Location: /mytest/servlet/Servlet1
Internal Servlet Error:
java.lang.NullPointerException

I am using Tomcat 3.2.1 on NT 4.0
The code for the servlet is the following:
package thing;
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
import java.util.*;
public class Servlet1 extends HttpServlet
{
//Initialize global variables
public void init(ServletConfig config) throws ServletException
{
super.init(config);
}
//Process the HTTP Post request
public void doPost(HttpServletRequest request, HttpServletResponse
response) throws ServletException, IOException
{
response.setContentType("text/html");
PrintWriter out = new PrintWriter (response.getOutputStream());
out.println("<html>");
out.println("<head><title>Servlet1</title></head>");
out.println("<body>");
out.println("Hello");
out.println("</body></html>");
out.close();
}
//Get Servlet information
public String getServletInfo()
{
return "thing.Servlet1 Information";
}
}
Thanks in advance!
