Unbind not working ?

#1 07-18-2008, 06:13 AM

I'm using MINA 2.0.0 M2 , java 1.6.
The problem is that IoAcceptor.unbind() doesn't seem to work . The clients
are not disconnected ( the disconnect is set ), and the port is not released
at all. Even after closing the program, the port is still used and freed on
a later time by the operating system.
My code for the unbinding operation is :
try
{
acceptor.unbind(new InetSocketAddress(portValue));

}
catch(Exception exception)
{
exception.printStackTrace();
}

acceptor is an IoAcceptor object, also, there is no exception.
I tried to browse the sources but I couldn't find the bind0 method used for
unbinding, only in some abstract version that needs implementing.
Maybe I'm doing something wrong ?

Thanks a lot

Could you please provide a sample program that demonstrates this behavior?

Thanks

Hi,

After more tests, it seems that it's more of a platform issue. While on
windows, it works fine, on Linux and Solaris, the problem appears. On linux
( I tested on Kubuntu 8 and Suse 10.3 ) , my tests indicate that the OS is
releasing the ports after a minute or so, while on Solaris the ports remain
in use until system reboot.
I mention that this problem does not appear with mina 1.1.7 which I
previously used.
I don't know what piece of code I might be adding to this mail to make
things clear, so I give you the svn checkout address for my source :
http://dshub.svn.sf.net/svnroot/dshub/trunk
The file that starts the mina server and handles port adding/removing is
HubServer.java and the IoHandlerAdapter subclass is SimpleHandler.java

Thanks for helping out
