Hello,
As I told still doing testing with the web sockets. It seems that a
reconnection doesn't fully work. I don't know why.
If the connection is the first the browser does. It works nice. The
server sends a message to the client (browser) and the browser responds
with a request for data.
That works nicely.
But when I reload the page, most of times doesn't work.

The server receives a connection. And in response it sends a message to
the client with a client ID. The client should respond. but it seems
browser never receives the message.
Why it doesn't work? Can connection be dropped or messages lost?
I added some logs to see if the socket is closed but it's ok.
@Override
public boolean sendMessage(ConnectionIdentifier identifier, String
message)
{
Application application =
Application.get(identifier.getApplicationName());
IWebSocketSettings webSocketSettings =
IWebSocketSettings.Holder.get(application);
IWebSocketConnectionRegistry webSocketConnectionRegistry =
webSocketSettings.getConnectionRegistry();
IWebSocketConnection connection =
webSocketConnectionRegistry.getConnection(application,
identifier.getSessionId(), identifier.getKey());
if (connection == null || !connection.isOpen())
{
log.warn("Connection is closed!!!");
return false;
}
try {
connection.sendMessage(message);
} catch (IOException e) {
log.warn("Cannot send message: {}", e.getMessage());
return false;
}
return true;
}
So Why I cannot send it. Or why the client is not receiving it?
Best regards,
