Hello
I am starting async requests inside a asyncSupported=true servlet.
After that, sometimes an event occurs and I need to dispatch a small
message to each client. For this purpose I use a executor that will
send this message to each client in an obvious way:
for (final AsyncContext ctx : clients) {
executors.execute(new Runnable() {
public void run() {
try {
if
(ctx.getResponse().isCommitted()) {
System.out.println("wow! why?");
return;
}
PrintWriter writer =
ctx.getResponse().getWriter();
writer .println(message);
writer.flush();
} catch (IOException e) {
e.printStackTrace();
}
}
});
}
After the firs message being sent for the client,
getResponse().isCommited is true. If I try to send the second message,
I will get an EOF exception.
Thanks
