It's been a year.... IIUC servicemix has done something so the specs
that have this discovery pattern solve the problem somehow. Now we
have a jaxws 2.2 spec with the same problem.
I think its silly to have the osgi-usable version of the spec far away
from the spec source code. Can we revisit this discussion?
I'd need to review what the servicemix bundles actually do but I'm
pretty much in favor of having the geronimo spec jars work in osgi
unchanged. If that's really unacceptable I'd suggest releasing two
artifacts, one a working osgi bundle the other a non-osgi plain jar.

Geronimo working in an OSGi environment.
All these jars have been published and work great :-)
However, lots of these spec jars define factories (stax, saaj for
example) that use the META-INF/services/ discovery mechanism to find
an implementation of the spec and load it. This mechanism does not
fit well in OSGi (really, it does not), mainly because usually, the
classloader containing the spec jar will not contain the
implementation.
I'd like to work on these spec jars so that they will contain an
OSGi BundleActivator that would change the behavior of these
factories when deployed in an OSGi environment (without changing the
behavior in other case). The idea is that the activator would scan
OSGi bundles when they are started to find META-INF/services and
populate a map that would be used by the factory when creating an
object before using the standard mechanism.
The only real difference compared to what we currently have would be
the addition of a package named org.apache.geronimo.specs.stax (for
example) that would contain the needed classes (i suppose two
classes), and the modification of the factories to delegate to one
of these class before using the standard behavior (the class would
do nothing if not deployed in an OSGi environment).
Has anyone any objection with such an enhancement in the specs jar ?
