This example shows how you can embed Apache ActiveMQ Broker and Camel in a web application, which can run on Apache Tomcat or other web containers.

Which will create a .war file in the target directly. You can then deploy this .war file in any web container such as Apache Tomcat, by copying the .war file to its /webapp directory.

For example to start Apache Tomcat

And then build the example and deploy to Apache Tomcat

The broker.xml file is located in the src/main/resources directory and contains:

The camel-config.xml file is located in the src/main/resources directory and contains:

You can use JConsole to get details about the running ActiveMQ and Camel. This is done by starting up jconsole, and then under local processes,
