[mina] Client hangs and sends no data
Sorry, missed an appropriate subject line ...
Hi,
I've got a problem with sending data from a client to a server using
MINA. Data are successfully written to ProtocolSession as I can see them
in the logging output. But they are never sent to the server: Absolutely
no data travels across the network; the client application hangs.
I've looked at your example application delivered with the MINA 0.7.4:
Sumup Client and Server. There are no real differences (by the way, the
example app works locally). The only difference obvious to me is usage
of DemuxingProtocolCodecFactory - I'm using a kind of ProtocolCodecFactory.
Maybe I've lost a simple thing to do?
Thanks for any help.
Christian

OK, let's try it:
Main thread idles here as expected:
while (session.isConnected()) {
try {
Thread.sleep(100); // <== HERE
...
The other threads are as follows:
------------------
Thread [SocketIoProcessor] (Suspended)
sun.nio.ch.WindowsSelectorImpl$SubSelector.poll0(long, int, int[],
int[], int[], long) line: not available [native method]

That's it.
On the server side there's only an openSession event in the log file -
nothing more.

By the way, there's another difference: We are talking SSL via MINA's
SSLFilter.

OK, I will try to extract all required classes to prevent sending the
whole content of our CVS repo ... :-)
Thanks in advance

Could you give me full thread dump for the application when it hangs? I need
to inspect it first to see if it is caused by therad pool filters.

It would be great if I can reproduce the problem by myself. Please e-mail me
the source code if you can provide it to me.
