Subject Re: upnp media server pure java

Hi Stefano

I'm aware of that, my question was more whether Jetty used NIO at all. I know the base driver
doesn't, but I've never looked at the Jetty source.

Hi Bruce and Surviant,

I would like to clarify which HTTP implementation is used by the Apache
Felix UPnP Base Driver, basedriver from now one. The only HTTP
implementation used by the basedriver uses the HTTP server developed by
CyberLink which uses jre-1.3 classes (so neither NIO nor MINA). In
particular, the basedriver depends on CyberDomo which is a patched
version of the CyberLink library so it uses the HTTP implemented by
CyberDomo library.

The Jetty HTTP implementation *may* be used by the UPnPDevice service
registered on the platform that are willing to be accessed by means of
presentationURL, as defined in the UPnP Device Architecture document.
Because the UPnPDevice *may* uses the HttpService defined by OSGi
specification, and the current implementation of the HTTP bundle
developed by the Apache Felix project uses Jetty.

At the end, to summarize:
-       Apache Felix UPnP Base Driver relies only on the CyberDomo HTTP
-       Jetty is used only by UPnPDevice which relies on the HTTP bundle
implementation developed by the Apache Felix project

Stefano "Kismet" Lenzi

P.S.: Surviant you are free to provide a patch either for CyberLink or
CyberDomo to enable NIO or MINA

provide the rendering application with a URL. Where that points is entirely up to you, but
would typically be to a servlet running in your media server application (probably using the
OSGi http service). Whether the http service uses NIO is another question altogether and I've
no idea about the default Jetty implementation shipped with Felix. But if you want to use
NIO, then you can always write something yourself that does.
