Does nobody@webserver have permission to open a X session on the
remove computer? Are you making some provision to keep this reference to
Process p alive so that it won't get garbage collected (and kill the
process) once the method completes?

Subject: servlet not quite working
I am trying to run a servlet that will pop an xterm up on the remote
computer. I do not get an error when compiling or calling the servlet, but
I don't get the xterm to pop up.
Here is the java file I am using:
import java.io.IOException;
import java.io.PrintWriter;
import java.util.Enumeration;
import javax.servlet.*;
import javax.servlet.http.*;
public class TestServlet extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse
response)
throws ServletException, IOException
{
PrintWriter out = response.getWriter();
response.setContentType("text/plain");
// Create command sring to run on server. request.getRemoteAddr()
will
// get you the ip address of the remote machine. The :0 sets the
display
number
//
String[] callAndArgs = { "/usr/bin/X11/xterm",
"-display " + request.getRemoteAddr() + ":0 &" };
// Some output to what we are doing
out.println("Test Servlet");
out.println("Remote Addr: " + request.getRemoteAddr());
out.println("Remote Command: " + callAndArgs[0]);
out.println("Remote Command Args: " + callAndArgs[1]);
out.println("If this works you should see an xterm");
out.println("Is you xserver running?( exceed maybe)");
// Get a our runtime object, then execute a process using our
command st
ring
Runtime rt = Runtime.getRuntime();
Process p = rt.exec(callAndArgs);
}
}
and here is the output I get:
Test Servlet Remote Addr: "correct ip address"
Remote Command: /usr/bin/X11/xterm
Remote Command Args: -display "correct ip address":0 &
If this works you should see an xterm
Is you xserver running?( exceed maybe)
Any ideas as to why I never get the actual xterm to popup on my computer?
