Console Example

Available as of Camel 2.10

This example is located in the Camel distribution at examples/camel-example-console.

This is a beginner's example that demonstrates how to get started with Apache Camel.

In this example we integrate with the console using the Stream component. The example is interactive - it reads input from the console, and then transforms the input to upper case and prints it back to the console.

This is implemented with a Camel route defined in the Spring XML markup shown below:

Wiki Markup
{snippet:id=e1|lang=xml|url=camel/trunk/examples/camel-example-console/src/main/resources/META-INF/spring/camel-context.xml}

This example can be launched from the command line using Maven:

Code Block
mvn compile exec:java

In the console you can enter a message and press <ENTER>. Camel responds by echoing the input message in upper case, as shown below:

Code Block
[onsole.CamelConsoleMain.main()] SpringCamelContext             INFO  Apache Camel 2.10 (CamelContext: camel-1) started in 0.455 seconds
Enter something: camel rocks
CAMEL ROCKS
Enter something: and we have fun
AND WE HAVE FUN
Enter something: 

To stop the example, strike Control+C

You can also run this example from your editor. For example, from Eclipse you can import this project using: File → Import … → Existing Maven Project, and select pom.xml from the examples\camel-example-console directory.

Next, navigate to the org.apache.camel.example.console.CamelConsoleMain class, right-click, and select Run As → Java Application.
