I am trying to learn Camel, and so I making an article that explain Camel's basic notions that a newbie has to know to understand Camel.
For this purpose, I am reading the book Camel in Action, where the authors define the following main concepts: - Messages - Exchanges - -------- - Processors? - Routes? - ------- - Components - Endpoints - Producers - Consumers *Clear notions:* Now after reading the book I have a clear notion that a Message is an object with a body, a header and some options, and that an Exchange is an object that contains two Messages (an In message and an Out Message) along with some extra information as well. *Not so clear, probably wrong notions:* I have the feeling the Processors are nodes that change the content of Exchanges. I believe that I cannot send a Message object to another endpoint using Camel, I can only use an Exchange with the InOnly parameter set (meaning it only has 1 message). I also believe that a Route is the junction of a start Endpoint, several processors, and an end Endpoint where the message is finally received. *No idea whatsoever:* As you can probably guess, I am super confused by components, endpoints, producers and consumers. Like, all I understand is that components are factories of endpoints and endpoints are factories of producers and consumers, but I really do not understand how this is suppose to matter to me nor do I understand how this reflects in code. I have also visited this discussion: - http://stackoverflow.com/questions/8845186/what-exactly-is-apache-camel But it did not help much, as I already learned all I could from it. Can someone clarify my **not so clear notions** and help me understand the rest of the concepts? I would be really grateful ! -- View this message in context: http://camel.465427.n5.nabble.com/Help-Understanding-Apache-Camel-main-concepts-tp5749818.html Sent from the Camel - Users mailing list archive at Nabble.com.
