WebResourceServlet is in an internal package not exported as class within Karaf

[verastoyanova]

Hello,
The how-to says:
Install the org.everit.osgi.webresource module into your OSGi container.
Install the WebResourceServlet (that is provided as an OSGi service) into your ServletContext.

I am having difficulties since WebResourceServlet is not exposed by the bundle at all (it is into the internal package), so even importing the WebResourceServlet into my bundle causes compiler problems since such a class is not visible at all.

How is one supposed to use the WebResourceServlet within Karaf 4.4. container. Do you have an example usage bundle ?

Best Regards,
Vera Stoyanova
