Hi *,

I guess, I have a misunderstanding about classloaders in OSGi and i
appreciate, if someone can engross those thoughts.

Here's a specific situation:

Bundle A exports exports stax-api and implementation WoodStox. Bundle B
has an import on just the stax-api (javax.xml.stream). Bundle B calls
'XMLInputFactory.newInstance();'.

Now whats going on? According to
'http://java.sun.com/webservices/docs/2.0/tutorial/doc/StAX4.html' it is
looking for file 'META-INF/services/javax.xml.stream.XMLInputFactory'
"in jars available to the JRE". Bundle B finds this file and because
bundle A exports the WoodStox-classes, everything works fine.

But why? Remember: Bundle A has no exporting advice for META-INF (if
thats ever possible) and bundle B has no importing on that.

I try to split bundle A in two bundles: Bundle A1 contains the stax-api,
bundle A2 the implementation (WoodStox). But now, when I call
'XMLInputFactory.newInstance();' in bundle B the file
'META-INF/services/javax.xml.stream.XMLInputFactory' is NOT found.

I don't get the point and hope, someone can bring light into my/the
darkness.

Cheers,
 Kevin
