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

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

    out.println("<HTML>");
    out.println("<HEAD><TITLE>Hello World</TITLE></HEAD>");
    out.println("<BODY>");
    out.println("<BIG>Hello World</BIG>");

Hi Nirlep,

Just add servlet.jar to your classpath.

I too got the same problem with the servlet
Can u explain me in detail HOW TO ADD SERVLET.JAR TO CLASSPATH
i have insatalled tomcat 5
I have read in a book that the JAVA_HOME variable has to be given the path of java where it has been installed
I found java in /usr/bin/share/java
Do i need to set a value to this variable?? If yes Please explain me how to do?

Bye Waiting for a nice reply
