REP deployment Quick Start

Software requirements

To build and run the REP example code you need to meet following requirements:

• Java 6.0 SDK ​http://java.sun.com/javase/downloads/index.jsp
• eclipse ​http://eclipse.org/downloads/
• REP example code: eclipse project 'REP'

The project makes use of the Java REST framework 'restlet' by ​http://www.restlet.org/. The required libraries are part of the eclipse project.

run the Example REP Project

In order to run the code samples please follow the steps below:

1. Import the eclipse project into your eclipse workspace
2. fix missing class path errors if required (e.g. if eclipse could not find a Java Sdk)
3. the project structure should look like this:

4. run uk.ac.surrey.sensei.rep.test.REPTest.java

The REPTest class provides a couple of test cases. Please uncomment the sections you want to have tested. By default REPTest.java creates a REP listening on HTTP port 8185. It attaches a RAIHandler of type SensorType? for a dummy light sensor. The hard coded light value is read from the file xml/sensors/light.rdf. It can be requested by a REST GET method call on ​http://localhost:8185/rep/s/light.

The response is the Observation and Measurement value in XML-RDF syntax.

REST client tools

GET and POST requests can be easily tested by using a web browser. For testing other REST methods like PUT, DELETE, and OPTIONS dedicated REST client tools are available, like:

• RESTClient: plug-in for Firefox: ​https://addons.mozilla.org/en-US/firefox/addon/9780
• Java GUI tool: ​http://code.google.com/p/rest-client/
• soapUI: ​http://www.soapui.org/userguide/rest/index.html
