<p>After installing it you would see a new tab "Script Console" in <a href="http://localhost:4502/system/console">Felix Web Console</a>.
The plugin screen provides a textarea to author script code. One can select the language via the given dropdown. The generated
output is shown in pane below.</p>
-<p>The script exposes following variables
-<em> <code>request</code> - Current HttpServletRequest instance
-</em> <code>response</code> - Current HttpServletResponse instance
-<em> <code>reader</code> - Direct access to the Reader of the request - same as request.getReader(). Use it for reading the data of an HTTP request body.
-</em> <code>out</code> - Direct access to the PrintWriter of the response - same as response.getWriter(). Use it for writing to the HTTP response body.
-<em> <code>osgi</code> - Provides convenience methods for scripts, mainly osgi.getService(foo.bar.Service.class) to retrieve OSGi services available in
- OSGi Container (Class notation depending on scripting language).
-</em> <code>bundleContext</code> - OSGi BundleContext instance for the script console plugin bundle. Can be used to access the OSGi runtime</p>
