HelloWorld OSGi Example
10+
=======================
11+
12+
This example demonstrates how to develop a simple OSGi WAR bundle
13+
containing a RESTful hello world web service
14+
15+
Contents
16+
--------
17+
18+
The example WAR (see the `war-bundle` module) consists of two Jersey
19+
resources:
20+
21+
`org.glassfish.jersey.examples.osgi.helloworld.resource.HelloWorldResource`
22+
23+
that produces a textual response to an HTTP GET
24+
25+
`org.glassfish.jersey.examples.osgi.helloworld.resource.AnotherResource`
26+
27+
that produces a different textual response to an HTTP GET. The
28+
purpose of this resource is to show how to define multiple web
29+
resources within a web application.
30+
31+
The mapping of the URI path space is presented in the following table:
32+
33+
URI path | Resource class | HTTP method
34+
------------------ | -------------------- | -------------
35+
**_/helloworld_** | HelloWorldResource | GET
36+
**_/another_** | AnotherResource | GET
37+
38+
Running the Example
39+
-------------------
40+
41+
To run the example, you would need to build the WAR file and install it
42+
to an OSGi runtime (e.g. Apache Felix) together with other OSGi modules.
43+
Look at the attached `functional-test` module for details on the
44+
programatical runtime configuration. To build the war archive and run
45+
the tests, you can just launch
46+
47+
> mvn clean install
