oliver z updated ARIES-780:
----------------------------
Description:
I'm trying to build a modular player for sites like jamendo. The problem is
that the streaming format is in mp3 (or ogg sometimes). The librarys providing
such support try to use the SPI mechanism of the JRE which is a problem in OSGi
environments.
So i'm really happy that this is adressed with SPI Fly - but its somehow not
working for me.
I tried the dynamic weaving:
added the asm bundle and the spi fly dynamic weaving bundle in the "bundle" dir
of apache felix (works fine, lb shows me that both bundles are running)
ID|State |Level|Name
0|Active | 0|System Bundle (4.0.1)
1|Active | 1|ASM all classes (3.2.0)
2|Active | 1|json simple OSGi Bundle (1.0.0.SNAPSHOT)
3|Active | 1|Mp3Wrapper OSGi Bundle (1.0.0.SNAPSHOT)
4|Active | 1|Apache Aries SPI Fly Dynamic Weaving Bundle
(0.4.0.SNAPSHOT)
the mp3wrapper contains the spi providers (mp3spi, tritounus share etc. for
playing mp3 files - they replace AudioInputStream and some others), so i added
in the MANIFEST.MF in mp3wrapper the following header:
SPI-Provider: *
the consumer is my playerengine bundle which contains the following line in its
manifest:
SPI-Consumer: *
when i start the OSGi container i get the following:

[PLAYERENGINE]: Default player engine registered!
so it does *something*, but it looks like errors. I got a reply that this is
just debugging output and the functionality should work.
But it does not. I wrote a little test in my playerengine bundle:
Type[] audioFileTypes = AudioSystem.getAudioFileTypes();
for(Type a : audioFileTypes)
{
System.out.println(a.getExtension());
}
if it would work, there should be:
wav (provided by JRE)
au (provided by JRE)
aif (provided by JRE)
mp3 (provided by mp3spi)
but the last one is missing, i cannot play mp3s, i get an exception:

maybe this is a bug? i'm not familiar with bytecode so i can't help nor go
deeper and check whats going on :(
the complete framework with my bundles and asm/dynamic weaving (running
example) can be downloaded here (2.3mb):
http://download.origo.ethz.ch/soundbox/3349/felix-framework-4.0.1.7z
thanks in advance
edit:
to run the application:
1) java -jar bin\felix.jar
then 2 windows should open
wait a little bit until "Jamendo plugin initialized" appears
2) now go the textfield where "Enter a keyword..." stands
enter something like "dire" and click on the "go" button
there should appear a list of songs in the table
3) click one so that it is marked and hit the button "add to player"
"add to player" tries to start the playback - the dynamic weaving happens
and the exception will be thrown

> maybe this is a bug? i'm not familiar with bytecode so i can't help nor go
> deeper and check whats going on :(
> the complete framework with my bundles and asm/dynamic weaving (running
> example) can be downloaded here (2.3mb):
> http://download.origo.ethz.ch/soundbox/3349/felix-framework-4.0.1.7z
> thanks in advance
> edit:
> to run the application:
> 1) java -jar bin\felix.jar
> then 2 windows should open
> wait a little bit until "Jamendo plugin initialized" appears
> 2) now go the textfield where "Enter a keyword..." stands
> enter something like "dire" and click on the "go" button
> there should appear a list of songs in the table
> 3) click one so that it is marked and hit the button "add to player"
> "add to player" tries to start the playback - the dynamic weaving happens
> and the exception will be thrown
