Re: how can I make multiple ProtocolCodecFilters work together?

[slowness chen <sl...@gmail.com>]

you have one protocolcodecfilter , e.g. "codec", you can judge which
protococodeclfilter is appropriate according to some conditions, then
replace "codec" with that protococodeclfilter :

session.getFilterChain().remove("codec");
session.getFilterChain().addLast( "codec", new ProtocolCodecFilter( new
MyCodecFactory( )));
