xml?
so what?
MuleContex context = Mule.newMuleContext();
Flow myFlow = new Flow();
myFlow.setName("MyFlow");
InboundEndpoint myIn = new GenericInboundEndpoint();myIn.setURL("file:///Users/porcelli/in");
OutboundEndpoint myOut = new GenericOutboundEndpoint();myIn.setURL("file:///Users/porcelli/out");
myFlow.setInbound(myIn);myFlow.addMessageProcessor(myOut);
context.addFlow(myFlow);
muleContext.start(); ok?
NO!
DSL!
➡ Expressive & Natural➡ Easy to Use & Learn➡ Hard to Misuse➡ Extensible
goals...
Mule.newMuleContext(new AbstractModule() { @Override public void configure() { flow("MyFlow") .from("file:///Users/porcelli/in") .send("file:///Users/porcelli/out"); } }).start();

remember?
feedback?
