Hi I have a situation where I am to replace a legacy server which has multiple clients and the communication is with a custom raw-byte format over TCP. I was thinking that camel MINA must be perfect for the task and have written a codec to encode and decode the messages.
However, the communication between the clients and server is mostly of type "fire and forget", where the client do not wait for an answer but some messages require a response. This means that neither the option sync=true nor sync=false will suffice. The clients do not have the option to connect to a certain port if an answer is required and another port if they require no answer. Therefore I must implement a server which, based on the message received, will return an answer or not return an answer. My question is if this is possible using the camel MINA component? I've made some experiments (JUnit tests) trying to change the ExchangePattern in a route from a MINA endpoint with sync=true with setExchangePattern(ExchangePattern.InOnly). By the looks of the printouts from the minaLogger that doesn't do anything and the request message to the endpoint is the same as the response to the client. The silver bullet for me would be an option like "sync=messageDependent" and in my implementation of ProtocolDecoder had the option to tell the MINA component whether to keep the connection open for reply or not. -- View this message in context: http://camel.465427.n5.nabble.com/Message-dependent-sync-with-MINA-tp5435721p5435721.html Sent from the Camel - Users mailing list archive at Nabble.com.
