I need a eg
Hi guys,
I'm trying to implement a very simple getURL (SVG) to pull sensor
data from a servlet and display it every millisec or so. Below is a
sketchy idea of what I have in mind.
How I can I implement a simple getURL()? Will it be something like
<svg ...........>
<script .......><![CDATA[
function acquire() {
getURL('/servlet/sensorservlet',fn)
}
function fn(obj) {
setTimeout('acquire()',1)
}
]]></script>
</svg>
Thanks for your help.

private int data; //data holds sensor value
public class Sensor extends HttpServlet
{
public void init(ServletConfig config) throws ServletException
{
super.init(config);
MyMonitor Monitor = new MyMonitor(); //data acquisition class
instantiated
data= Monitor.start(); //method polls sensor for data
} //end of init
protected void doGet(HttpServletRequest req, HttpServletResponse
res)
{
res.setContentType("text/html");
res.setHeader("pragma", "no-cache");
ServletOutputStream out = res.getOutputStream();
out.print("<HTML><HEAD><TITLE>Sensor
Data</TITLE>/head>");
out.print("Sensor Data<BR>");
out.print(data);

-
out.print("</HTML>");
out.close()
} //end of doGet
} // end of Sensor Class
