Re: [HAPI-devel] Trouble receiving messages usubg SendAndReceiveaMessage example

I'm receiving this message from another server (I don't know why). We're building an interface between our app and a HL7 server, and the first step is just getting the HL7 messages off the wire and storing them. The Reciever implementation is making a hard coded policy decision that my application that's using it does not want to know about some HL7 messages. This should be configurable, at the very least ? I've had a rough delve through the code, and it seems because Reciever isn't an interface, you have to replace whole chunks of other classes as well - I think I ended up with over a half dozen cloned classes in my package because thing's were private or package and so I couldn't extend them easily. Maybe it would be easier to have a setting (in HapiContext) about what to do with them ?
