Write called not within mina handlers problem.
Hi All,
I have the following problem:
When connection established I add a IoSession object to different
object, which some times needs to send a message to all connected
sockets.
The thing is that when I use IoSession.write(ByteBuffer) it is being
logged but not sent.
Do I use Mina wrong?
Thank you in advance,
Roman

ByteBuffer.flip();
IoSession.write(ByteBuffer);

Are you using the same ByteBuffer instance to broadcast a message?
Then it can be a problem because ByteBuffer position will be changed
per each write. The solution is to create duplicate buffers. It
performs well because it doesn't copy the content of the buffer but
the position and the limit value:
ByteBuffer message = ...;;
Collection<IoSession> sessions = ...;
for (IoSession s: sessions) {
s.write(message.duplicate());
}
HTH,
Trustin
