Sorry, i cant compile servlets or jsps. I have tomcat5.0 installed am using j2sdk but i get errors like javax.servlet does not exist. I cannot find servlet.jar in my tomcat installation; i read it was in %catalina_home%in tomcat4.x. What i'm asking is what do i need to compile a servlet? How do i do it? Very grateful to any replies..

No there's no j2ee.jar and no servlet.jar in %CATALINA_HOME%\common\lib; the nearest thing here is servlet-api.jar. This is the output i get when i try to compile HelloServlet.java;
Output from compiler
HelloServlet.java:2: package javax.servlet does not exist
import javax.servlet.*;

HelloServlet.java:3: package javax.servlet.http does not exist
import javax.servlet.http.*;

location: class HelloServlet
public class HelloServlet extends HttpServlet {

location: class HelloServlet

My environment variables are

Code:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloServlet extends HttpServlet {
public void doGet(HttpServletRequest request,HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html");
PrintWriter out = response.getWriter();
String docType =

out.println(docType +
