This repository contains two Java 8 examples of how to use the Darwin v16 messages from the National Rail Open Data platform, located at the following URL:
To use this service, you will need to sign up for a free account and subscribe to the 'Darwin' feed.
Edit src/main/resources/application.properties, uncomment and set the username,
password and hostname keys to the values shown on the 'My Feeds' page.
To customise the JMS Client ID sent to the ActiveMQ server, change the definition
of this.clientId in the constructor method for DarwinClientRouteBuilder. You
do not need to change this unless you will have more than one client subscribing
to the topic.
The messages are produced in XML format, and a good way to consume them is by using generated classes with JAXB.
Using Maven, run the following command:
mvn jaxb2:xjc
This will generate classes in target/classes. You may need to mark the
generated-sources directory in your IDE as a generated sources root.
The code has been written on Java 8 with Apache Maven. Other versions of Java have not been tested.
Running the DarwinClient class will show the raw message body and print the
timestamp from the parse XML through the classes generated by JAXB.
