Running the example

To run the example we use the Camel Maven Plugin.

For example from the source or binary distribution the following should work

You should now see the generated files in the target/outputFiles directory which are the transformed messages read from the JMS queue.

What this does is boot up the Spring ApplicationContext defined in the file META-INF/spring/camelContext.xml on the classpath. This is a regular Spring XML document which uses the Camel Xml Configuration to configure a CamelContext.

Also note at the end of this XML example file we explicitly configure the ActiveMQ component with details of how to connect to the broker.

The main part of the Spring XML file is here...
