Comment: Migration of unmigrated content due to installation of a new plugin

Here's how to run it with Maven:

Whats happening?

When you start the example up you'll see a whole bunch of logs that won't really mean anything to you (smile) The interesting stuff is happening in the background. Here's a diagram of whats going on.

...

At step 1 the SendFileRecordsToQueueBean polls the ./src/data directory for new files. There are 3 files in this directory so 3 messages will be created. As shown below, the @Consume annotation will cause any new messages coming from the file:src/data endpoint to be sent to the onFileSendToQueue method.

...

...

At step 2 the SendFileRecordsToQueueBean then sends the contents of the File message as a String to the personnel.records JMS queue, which is backed by an embedded instance of Apache ActiveMQ. The conversion from String to JMS message is automatic. The @Produce annotation is used to access the ActiveMQ endpoint.

At step 3 the DistributeRecordsBean (shown below) consumes the JMS message from the personnel.records queue. Again the @Consume annotation is used to get messages from the ActiveMQ endpoint.

...

You will notice an additional @RecipientList annotation on the route method. This turns the method into a Recipient List EIP where the return value is a list of URIs for the recipients (can be String[], List<String>, URI[], etc). This annotation is great for creating custom dynamic Recipient Lists. In this case at step 4 we peek at the city field in the message (using the @XPath annotation) and provide a set of recipients based on that. For folk from London, their files will be sent to file locations for the EMEA region (file:target/messages/emea/...). Others fall into the AMER region (file:target/messages/amer/...).

...

...

If you have messages that are not XML, don't fret! Camel has ways to get information out of arbitrary message payloads. For instance, you can try using the @Bean annotation to peek at the message using your own Java bean.

Check out Parameter Binding Annotations for more information on this.

After running the example, browse to the target/messages directory to see where the messages were saved.
