Tom,
Sorry for not giving the details. Let me correct my mistake.
I have a situation where I need to push data from server side java
application to the flex client. Some processes running on the server
will generate alerts which need to be passed to the Flex client. I
use FDS and JMS successfully for some areas of the project where the
traffic is high and server constantly pushes data.
Since the alerts will be sporadic, creating a JMS topic seem an
overkill. So I decided to take advantage of Tomcat 6's Comet data
streaming feature. I wrote a prototype pushlet on the server side
which pushes string messages to the client as soon as the connection
with the client is established.
Here's how the pushlet looks
public class PushServlet extends HttpServlet implements
CometProcessor {
public class MessageSender implements Runnable {
protected boolean running = true;
public MessageSender() {
}
public void stop() {
running = false;
}
public void run() {
while (running) {
synchronized (connections) {
// Send any pending message on all the open
connections
for (int i = 0; i < connections.size(); i++) {
try {
PrintWriter writer = connections.get
(i).getWriter();
for (int j = 0; j < 10; j++) {
writer.println("Push
message "+j);
writer.println("<br>");
}
writer.flush();
} catch (IOException e) {
System.out.println("IOExeption
sending message"+e.getMessage() );
}
}
}
}
}
}
}
This part runs fine when I hit the url
http://localhost/myproject/pushlet
On the flex side, I wrote the following http service to establish
connection to the pushlet
<mx:HTTPService id="push" url="http://localhost/myproject/pushlet";
result="showResult();" />
I put push.send() in creationComplete of the application and
showResult() just has an Alert.show("Hi"); to indicate that
HTTPService did return something.
But this is not working. Let me know if there's a way to make this
work.
Regards,
Amit
