This project is a very simple RESTful client demo application. It runs on Java 1.6 or newer.
The application will send a request to my corresponding JAX-RS REST server demo, which is a rather silly karaoke song request service. The client will send the name of a song (Macarena by default, but you can change this in the source code) and then print the result in the terminal.
You can easily build the code directly from within your IDE of choice (I'm personally rather fond of Eclipse), using its build features (in Eclipse, right click the project and select Run As -> Maven build, type package into the Goals field, then Run). If you prefer doing stuff more old school, you can use the command line to build the project as well. To do so, you need to have Maven installed on your machine. Navigate to your project location. Then, simply type
mvn package
in your terminal. Your generated JAR files can be found as ./target/jaxrs-rest-example-client-1.0.0.jar and ./target/jaxrs-rest-example-client-1.0.0-with-dependencies.jar.
The easiest way of running the code is directly from within your IDE of choice, simply by hitting the Run button (in Eclipse, that is). If you prefer running your code from the command line, navigate to the project location and type
java -jar target/jaxrs-rest-example-client-1.0.0-with-dependencies.jar
That's it.
