How do I unbind a server socket once I call bind()

[Christian Migowski]

not sure if i understand your problem correctly, do you mean this:

a) if this doesn't cause problems in your environment (i.e. only one
instance of your app running in this jvm or classloader) you can make
the ChannelGroup static as in Trustins example

b) if a) isn't feasible just pass a reference to the ChannelGroup to
your handler (e.g. add a ChannelGroup parameter to your
PipelineFactory and Handler constructors)

hth,
christian
