Consuming REST services from a Java app

A simple JAX-RS Client usage example. Fetches weather data from a openweathermap.org and displays that on a simple Vaadin UI. See the related article, consuming REST servevices from Java apps.

To run the example, get a free API key from openweathermap.com and put it to file src/main/resources/META-INF/apache-deltaspike.properties

Use a JAX-RS 2.0 compatible server (~ Java EE 7 ) to deploy the app. Wildfly plugin is in the pom.xml, so an easy method is just to execute:

mvn wildfly:run
