Blocker Description
Tracking the problem described in DIRLDAP-28 jira issue, I finally discovered that data are not sent through the socket using a WritableByteChannel. I replaced it by an OutputStream in the OutputCallback inner class, added a flush() in the encodeOccurred method, and everything went well, ethereal was quite happy to show a LDAP packet with the full (correct) BindRequest.
My OutputCallback innerclass :
class OutputCallback implements EncoderCallback {
// private WritableByteChannel m_channel = null; // Does not send data, don't know why?
private OutputStream m_out; // back to old API
/**
- Callback to deliver a fully encoded object.
- @param encoder
- the stateful encoder driving the callback
- @param encoded
- the object that was encoded
*/
public void encodeOccurred(StatefulEncoder encoder, Object encoded) {
try {
ByteBuffer[] buffers = (ByteBuffer[])encoded;
for (int i=0; i<buffers.length; i++)
{ m_out.write(buffers[i].array()); } m_out.flush(); // don't forget to flush !!!
} catch (IOException e)
}
void attach(WritableByteChannel channel)
{ m_channel = channel; }void attach(OutputStream out)
{ m_out = out; // m_channel = Channels.newChannel(out); }I also tried to close the channel instead of using an OutputStream (just by replacing flush by a close), but that is not an option : you can't anymore read the response...
I may have missed something about channels? Or is this a bug? I'm not very experienced with NIO (the hendrix way of being experienced...), but I'll tried to improve my knowledge by browsing Sun code, just to check. Didn't had time to test it unde M$, but I gonna switch on my close source machine in a couple of hours.
Whatever, I still can't get a correct answer :
