Hi David
You're right, this looks doable.
However, looking further into my non-OSGified library, I see code like
Thread.currentThread().getContextClassLoader().getResourceAsStream(..)
:-( This won't find the resource in the bundle classpath, as far as I can see.
It seems non-trivial to develop a library that works both in JEE and OSGi.

Hi Martin,
If you use the static weaving with SPI Fly it should be of very low
impact. It will basically create you a modified bundle that works in
OSGi. It has a dependency the SPI Fly static bundle, but you should be
able to merge those classes in...
Cheers,
David

Hi David
Thanks! I actually came across SPI-Fly before posting, but it seemed like
a "big thing" to introduce at the current situation with my project.
What I would like in the short term is to inline the library (2 artifacts)
and "fix" some of the classes, ie. provide my own code for them.
I think it can be achieved with
<Embed-Dependency>scope=compile|runtime;artifactId=a1|a2;inline=true;inline=!**/SP.class;inline=!**/RP*.class</Embed-Dependency>
However, the instruction
inline=!**/SP.class;inline=!**/RP*.class
to exclude a total of four classes does not work quite right.
I also tried
inline=!**/SP.class|**/RP*.class
without any luck.

Hi Martin,
You may want to take a look at the SPI Fly component in Apache Aries:
http://aries.apache.org/modules/spi-fly.html - this allows you to do
this relatively easily.
Additionally, the OSGi Enterprise Spec 5 chapter 133 covers this [1].
Cheers,
David

Hi
From an OSGi bundle I need to call a library that itself uses
ServiceLoader to lookup/load a service provider class.
This does not seem to work, however.
java.util.ServiceLoader.load(x.api.z) returns no providers.
I embedded the library, so both file META-INF/services/x.api.z and class
x.spi.z are part of my bundle JAR.
I thought this would be enough to get ServiceLoader to work, but no :-(
Any ideas?
I already tried
ClassLoader thread =
Thread.currentThread().getContextClassLoader();
Thread.currentThread().setContextClassLoader(getClass().getClassLoader());
<call-library>
Thread.currentThread().setContextClassLoader(thread);
in case TCCL would be the problem, but that didn't help.
