actually I ran some local tests and there does appear to be a difference
between 2.0.7 and 2.0.9 when it comes to picking up a customized jar
manifest that's generated as part of the same build.

(there's some code inside the bundle mojo that checks the settings for
the maven-jar-plugin so it can merge any customized manifest with the
bundle generated one - this feature was required by apache commons)

looking at the GlassFish build pom for "javax.ejb" it uses jar packaging,
adds both the bundle and manifest goals, and sets the maven-jar-plugin
to use the generated manifest under "target/classes/META-INF/..."

in 2.0.7 the manifest goal runs first and generates a manifest without
the "javax.xml.rpc.handler" (because Bnd for some reason isn't taking
the Include-Resource instruction into account - possibly because we
don't actually build the bundle but just analyze the classpath...)

anyway, this generated manifest is _not_ picked up when the bundle
goal runs (possibly because of a bug in Maven wrt. detecting changes
to the build - I think this was one of the major changes in 2.0.9...) and
the final bundle has the correct manifest

in 2.0.9 the same thing happens, except this time the bundle goal can
see the generated manifest (without the "javax.xml.rpc.handler" entry)
and merges it with the generated bundle manifest - unfortunately the
entries from the custom jar manifest take priority, and so the bundle
ends up with the incorrect Export-Package entry.

getting the manifest and bundle goals aligned has been a rocky road
and it's still not an exact match as you can see - but I hope to sort
this out in the next release, as part of a push to improve usability

for now there is a simple workaround you can use to fix the problem:

<manifestLocation>${pom.build.directory}</manifestLocation>

which means the bundleplugin will write the generated manifest from
the manifest goal in a different place (not "target/classes/META-INF")
and therefore this won't be picked up when the bundle goal runs.

I've tested this locally and the build is the same on 2.0.7 and 2.0.9

I do have such outputs and they do not differ in the section that relates to the
felix plugin. Are there any other sections that I can look at?

Re: upnp media server pure java

It can use protocols specified in the resource description provided by the content directory.
However, HTTP is the protocol which is typically used.

2008/10/6 Survivant 00 <survivant00@...>
thanks nice article.

in my case the PS3 is the media renderers and the control point (send the play, FF, stop).. but still need to trace where the control point command is received in the media server and how the media server send data back (streaming) (it as to take the data somewhere. )

I,m trying the library Platinum in C++ (it's not java :( )

I had trace all the incoming/outgoing requests (SAOP) from the PS3 to my cybergate server, but nothing is stream yet. Maybe the cybergate implemenation is not complete, that's why I wanted to find a working demo in java. I didn't find any yet.

2008/10/6 Jackson, Bruce <brucej@...>
That's because Google Media Server, Tversity and Cybergate are media servers and NOT media renderers, and therefore they have no AV Transport service.
I suggest that you should take a read of:

http://www.upnp.org/standardizeddcps/documents/UPnPAvArchtiecture0.83.pdf

As this explains quite clearly the role of media servers and renderers, and the services that they provide.

In order to play media you will need to find another device which supports the AVTransport service. This has the play() and stop() actions.

Agreed, and I know the PS3 is a only a player, my question was why Google Media Server, Tversity or cybergate media server are not detected as AVTransport service ?

because the 2 previous services, will list was media is available, but doesn't have to had them on there server, it can be on the server than reside the AVTransport service.

do you have a sample of AVTransport service (prefenrencly in java) and how the mapping is done between the application that had the contentdirectory and the connectionmanager services ?

for Jetty, I think the latest version can use NIO from grizzly (http://weblogs.java.net/blog/jfarcand/archive/2007/11/jetty_616_is_ou_1.html)

2008/10/6 Jackson, Bruce <brucej@... <http://brucej@...> >
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.

Thanks

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
implementation
- Jetty is used only by UPnPDevice which relies on the HTTP bundle
implementation developed by the Apache Felix project

Ciao,
Stefano "Kismet" Lenzi

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

Jackson, Bruce ha scritto:

> Streaming isn't done by the UPnP library at all. All the Content directory does is to 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.
