FPMonitor.close() hangs application
Hi,
we use latest version of Centera SDK with C* 4.x and Java 6. We connect us to the Centera and initiate an register4AllEvents(). When we call FPMonitor.close() this function never returns and hangs our whole application (not the system).
Does anyone know why or if there is another way to close the connection to the Centera without calling FPMonitor.close()?
Greetings Marco

I believe that you should be calling eref.close() before fpmon.close(). The eref (FPEventRef object) will be using fpmon (the FPMonitorRef object), so logically you should close eref before attemtping to close fpmon.
This may not solve your problem but it is certainly worth trying.

Prior to closing the monitor connection, have you closed the EventCallbackRef that you received when your registered a stream for the events?

ok, i will try this and then come baqck with the result. I think documentation says close fpom before closing the callback reference and underlying streams.

No .
I have this:
private FPMonitor fpmon;
private FPMonitor.FPEventRef eref;
private BufferedOutputStream fsref;
register4allEvents is implemented like this:
if (fpmon != null && fsref != null){
eref = fpmon.registerForAllEvents(fsref);
if (eref == null){
// Here i do some error handling and logging
.....
close is done as follows:
public void close() throws FPLibraryException {
fpmon.close();
fpmon = null;
eref = null;
}
If i left out fpmon.close() all works but if i want to do a clean close auf my connection i do not get any farther than fpmon.close() call.

Graham,
thanks for your help. I've modified my script to call eref.close() before fpmon.close() and now it works.
