I have the same problem with Apache/Jserv. All servlets use
a pool of global static variables and methods defined in
a class Globals. Each servlet kicks-off its own JVM so
I end-up using more memory. Luckily,
variables are read-only.
So, I would like to know the solution too.

Subject: Sharing static variables between servlets.
Hi all,
I'm having trouble with what should be a simple feature: sharing a static variable
between two instances of the same servlet class.
Take the following example to demonstrate the problem...
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class MyCounter extends HttpServlet
{
private int counter = 0;
static int globalCounter = 0;
public void doGet(HttpServletRequest req, HttpServletResponse res) throws
ServletException, IOException
{
res.setContentType("text/html");
PrintWriter out = res.getWriter();
out.println("<HTML><BODY>");
out.println("Count ="+(counter++)+"<br>Global count = "+(globalCounter++));
out.println("</BODY></HTML>");
}
}
>From here I configured the Servlet Attibutes twice with distinct names, but both
>pointing to the same class. I then configured two virtual paths for each of these
>servlets. However, they then run independently of each other: i.e. as though each
>servlet were running in a seperate JVM? The static counter behaves just as though it

>class?
FYI: I'm using Netscape Enterprise Server 4 SP1.
Thanks in advance.
David Finch.
