Classloading question

[dmlloyd]

This is probably a dumb question. In a jboss-classloading.xml file, the root "classloading" element has a name and version attribute. Is doing this:

<classloading name="blah" version="1.0.0.GA"/>

the same as doing this:

<classloading>
 <capabilities>
 <module name="blah" version="1.0.0.GA"/>
 </capabilities>
</classloading>

??

Yes.

See VFSClassLoaderPolicyModule::determineCapabilities.

I see. One more dumb question whose answer I can't ascertain from the code: If I specify a version on the "classloading" element, is that version number inherited by default to all the nested capabilities (package and module)?

Looking at the code I doubt it.
As it's simple xml parsing and I don't see where we would explicitly override
the version if it was null with the one from parent classloading element.

Can you just try and let us know? :-)

If it's not there, it might be useful to add it.
But not for all capabilities - e.g. re-export or uses.
