This isn't completely unexpected. The DynamicClient things call off to xjc
to generate code, then they need to compile it. On Java6, we can use the
built in tools stuff to call the compiler which takes into account the
classloader (I think). On Java5, we have to call off to javac. To do so, we
need to build up a classpath. With a normal app, we can traverse up the
classloaders and find all the URLClassLoaders and grab the URL's for the Jars.
For OSGi, we cannot do that. Thus, it's not completely surprising that it's
not working, but I also don't have a solution.
We could add a method to JaxWsDynamicClientFactory to allow you to set/force a
classpath, but then you would need to discover and manage all that. Beyond
that, we would probably need a bundle listener or something that would record
all the started bundles and create a classpath (if we can) and use that. Not
really sure.
