<h1>JSONP Example</h1>
<p>This example demonstrates how to use JSONP wrapper in order to serve
not only JSON but also a JavaScript expression representing a function call with the original JSON data as a parameter.
The technique is well described e.g. at <a href="http://en.wikipedia.org/wiki/JSON#JSONP">http://en.wikipedia.org/wiki/JSON#JSONP</a>.
<p>A simple web application is presented with just one resource: a change record list. A client can obtain
the list using XML or JSON or JavaScript representation. The last change record is also available in all three formats
as a subresource of the previously mentioned list resource.
<h2>Contents</h2>
<p>The change record list web resource is implemented by <code>org.glassfish.jersey.examples.jsonp.ChangeListResource</code> class.
<p>The mapping of the URI path space is presented in the following table:</p>
<table border="1">
<tr>
<th>URI path</th>
<th>Resource class</th>
<th>HTTP methods</th>
</tr>
<tr>
<td>/changes</td>
<td>ChangeList</td>
<td>GET</td>
</tr>
<tr>
<td>/changes/latest</td>
<td>ChangeList</td>
<td>GET</td>
</tr>
</table>
<h2>Running the Example</h2>
<p>Run the example as follows:</p>
<blockquote><pre>
mvn clean compile exec:java</pre></blockquote>
<p>This deploys the JSONP example using
<a href="http://grizzly.java.net/">Grizzly</a>
</p>
<p>A <a href="http://wadl.java.net/#spec">WADL description</a> may be then accessed at the URL:</p>
<blockquote><code><a href="http://localhost:8080/jsonp/application.wadl">http://localhost:8080/jsonp/application.wadl</a></code></blockquote>
<p>Following steps are using <a href="http://curl.haxx.se/">cURL</a> command line tool:
<p>Get the list of changes in JSON format:</p>
<blockquote><pre>curl -HAccept:application/json http://localhost:8080/jsonp/changes</pre></blockquote>
<p>Get the list of changes in XML format:</p>
<blockquote><pre>curl -HAccept:application/xml http://localhost:8080/jsonp/changes</pre></blockquote>
<p>Get the list of changes as a JavaScript callback:</p>
<blockquote><pre>curl -HAccept:application/x-javascript http://localhost:8080/jsonp/changes</pre></blockquote>
<p>You can also see test classes at <code>src/main/test</code> subdirectory
for detail information how to consume the service using Jersey client API</p>
<h3>JavaScript Client</h3>
<p>After starting the service and refreshing this page, a list of changes should be displayed below:
<div id="writehere">
<script language="javascript">//<![CDATA[
var headLoc = document.getElementById("scriptComesHere");
var scriptObj = document.createElement("script");
scriptObj.setAttribute("type", "application/x-javascript");
scriptObj.setAttribute("src", "http://localhost:8080/jsonp/changes");
headLoc.appendChild(scriptObj);
//]]</script>
You need to run the service first!
</div>
