Dear QPID users,
I am using the QPID JMS client API (version 0.3.0). (I don't have
information about the broker.) I don't have much experience in using the
Qpid Messaging API.
Last week I detected an unexpected disconnection. These are the last qpid
API log entries.

However my application ran on.
I thought that I will get an exception, if I trying to send a messages after
the connection was closed. But I could send further requests without any
exception.
Is the connection still open or closed?
I have read that the API tries to establish the connection again. But I
couldn't find any hint in the log files. (Maybe I ignored the logger.)
How can I handle these disconnections? Do I need an ExceptionHandler? How
can I distinguish between recoverable and these fatal errors?
Thank your for your help.
Regards
Henry
