------------------------------------
Resolution: Fixed
This issue is now resolved. Thanks Oliver for filing it!
> problem getting mp3spi working with dynamic/static weaving
> ----------------------------------------------------------
>
> Key: ARIES-780
> URL: https://issues.apache.org/jira/browse/ARIES-780
> Project: Aries
> Issue Type: Question
> Components: Subsystem
> Affects Versions: parent-0.4.0
> Environment: win7 x64, apache felix 4.0.1 and equinox 3.7.1
> Reporter: oliver z
> Assignee: David Bosschaert
> Priority: Minor
>
> 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:

> 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:

> 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
