In the next sample, we have a more common use case where we expose a TCP service on port 6201 also use the textline codec. However, this time we want to return a response, so we set the sync option to true on the consumer.

from("mina2:tcp://localhost:" + port2 + "?textline=true&sync=true").process(new 
Processor() {
    public void process(Exchange exchange) throws Exception {
        String body = exchange.getIn().getBody(String.class);
        exchange.getOut().setBody("Bye " + body);
    }
});

Then we test the sample by sending some data and retrieving the response using the template.requestBody() method. As we know the response is a String, we cast it to String and can assert that the response is, in fact, something we have dynamically set in our processor code logic.

String response = (String)template.requestBody("mina2:tcp://localhost:" + port2 + 
"?textline=true&sync=true", "World");
assertEquals("Bye World", response);
