I am appending a simple example servlet:
------------------------------CUT------------------------------
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class Hello extends HttpServlet {
public void doGet (HttpServletRequest request, HttpServletResponse response
) throws ServletException, IOException {
PrintWriter out;
response.setContentType("text/html");
out = response.getWriter();
out.println("<HTML><HEAD><TITLE>Hello</TITLE></HEAD><BODY ");
out.println("bgcolor=\"#FFFFFF\"><H1> Hello World </H1></BODY></HTML>");
out.close();
}
}
------------------------------CUT------------------------------
Notice I have to extend HttpServlet. Based on the TclJava man-page
(correct me if I am missing something) it does not seem to be possible
to define or extend a Java class within TclJava.
Is there a way to do this? How? Could you re-write this bit of code in
TclJava? Or is there some way of organizing the code so that the
servlet code (the stuff inside doGet) can call Tcl functions which I
define somewhere else using Tcl language constructs?
Thanks for your help.
