This is a small Java project initially developed for a class on distributed Java (mostly Java EE and Spring).
The code consists of both a client and a webapp that provides
a trivial calculation capability to illustrate using JAX-RS
using Jersey. There's also a useful EmbeddedServer class that allows
the webapp to be run as a standalone Java application. The project
can also be built as a WAR using Maven.
This project is similar to (and based on) my Spring WebMVC project.
