Since we're on a major migration process of this website, some component documents here are out of sync right now. In the meantime you may want to look at the early version of the new website
We would very much like to receive any feedback on the new site, please join the discussion on the Camel user mailing list.
Walk through an Example Code
This mini-guide takes you through the source code of a simple example.
This example is available in the
We start with creating a CamelContext - which is a container for Components, Routes etc:
In normal use, an external system would be firing messages or events directly into Camel through one if its Components but we are going to use the ProducerTemplate which is a really easy way for testing your configuration:
This will start all of the configured routing rules.
So after starting the CamelContext, we can fire some objects into camel:
From the ProducerTemplate - we send objects (in this case text) into the CamelContext to the Component test-jms:queue:test.queue. These text objects will be converted automatically into JMS Messages and posted to a JMS Queue named test.queue. When we set up the Route, we configured the FileComponent to listen off the test.queue.
The File FileComponent will take messages off the Queue, and save them to a directory named test. Every message will be saved in a file that corresponds to its destination and message id.
If you have the time then use 5 more minutes to Walk through another example that demonstrates the Spring DSL (XML based) routing.
