DatagramAcceptor doesn't configure a user-defined FilterChain configuration on
bind.

Key: DIRMINA-222
URL: http://issues.apache.org/jira/browse/DIRMINA-222
Project: Directory MINA
Type: Bug
Versions: 0.9.4
Reporter: Trustin Lee
Assigned to: Trustin Lee
Fix For: 0.9.5
A bug report from Rob Butler:
Hello all,
I just started using the Spring integration package for Mina 0.9.4 and ran into
a problem. It seems as though the DatagramAcceptor doesn't make use of the
DatagramAcceptorConfig properly because any filters in the config are not used.
To confirm this was not a spring specific problem I re-implemented all the
configuration in code. Please see below:
IoAcceptor datagramAcceptor = new DatagramAcceptor();
IoAcceptor socketAcceptor = new SocketAcceptor();
DefaultIoFilterChainBuilder fcBuilder = new DefaultIoFilterChainBuilder();
fcBuilder.addLast("LOGGER", new LoggingFilter());
fcBuilder.addLast("CODEC", new ProtocolCodecFilter(new MyCodecFactory()));
DatagramAcceptorConfig datagramConfig = new DatagramAcceptorConfig();
datagramConfig.setFilterChainBuilder(fcBuilder);
SocketAcceptorConfig socketConfig = new SocketAcceptorConfig();
socketConfig.setFilterChainBuilder(fcBuilder);
socketAcceptor.bind(new InetSocketAddress( PORT ), new MyProtocolHandler(),
socketConfig);
datagramAcceptor.bind(new InetSocketAddress( PORT ), new MyProtocolHandler(),
datagramConfig);
As you can see the same DefaultIoFilterChainBuilder is being used for both the
SocketAcceptor and the DatagramAcceptor. The SocketAcceptor works fine and all
filters and the codec are invoked. The DatagramAcceptor does nothing and no
filters are invoked. If I manually register the filters in the
MyProtocolHandler.sessionCreated method everything works fine. But I'd rather
control these using the acceptorConfigs.
