> We will build an ims-component to communicate with our [IMS|http://en.wikipedia.org/wiki/Information_Management_System] system.
> As described in the Netty documentation in chapter [1.7.2. The First Solution|http://docs.jboss.org/netty/3.1/guide/html_single/index.html#d0e865], I assume that we need a state full SimpleChannelHandler (class annotated with @ChannelPipelineCoverage("one")). The proposed solution is to use a ChannelPipelineFactory which creates a new ChannelPipeline and a new SimpleChannelHandler for each Channel.
> {code}
> public class TimeClientPipelineFactory implements ChannelPipelineFactory {
> public ChannelPipeline getPipeline() {
> ChannelPipeline pipeline = Channels.pipeline();
> pipeline.addLast("handler", new TimeClientHandler());
> return pipeline;
> }
> }
> {code}
> In the current implementation, this is not possible IMO. The custom handler, which is looked up from the registry, is shared between all channels:
> {code}
> channelPipeline.addLast("handler", consumer.getConfiguration().getHandler());
> {code}
> If I'm right, I would like to provide the patch (but unfortunately not in the next two weeks).
> Thanks,
> Christian
> P.S: Very nice/clean code inside this component... :-)
