UnifiedClassLoader.getResources not working

[laurent.wozniak]

Hello,

I've just moved from JBoss 2.4.x to 3.0.x
and found the following bug:
UnifiedClassLoader.getResources() does not return all the
resources under a specific name.

UnifiedClassLoader.getResource() can return a value while
UnifiedClassLoader.getResources() is returning an empty enumeration for the same resource.

I looked in the source code and found that:
* UnifiedClassLoader inherit from URLClassLoader
* UnifiedClassLoader override getResource()
* UnifiedClassLoader does not override getResources()

UnifiedClassLoader.getResources() is simply not implemented.

HeirarchicalLoaderRepository does not implement this
functionnality either.

Does this feature will be supported by JBoss 3.0.x ?
If not, I can try to do it.

At least UnifiedClassLoader.getResources() should be
implemented to throw an UnsupportedOperationException.

Cheers,
Laurent

If you can implement it, go ahead, and send a patch.

I am interested in that feature too.
Could you provide use case ?

let's say I have package a.b.c and I put
two files in a/b/c if the jar.

what will getResources("a/b/c") return exactly ?
an enumeration of only the files ?
files + subpackages ?

I've posted the bug and the corresponding patch at sourceforge:
http://sourceforge.net/tracker/index.php?func=detail&aid=692157&group_id=22866&atid=376685

> what will getResources("a/b/c") return exactly ?
From java.lang.ClassLoader:
Finds all the resources with the given name

If you have resources with the same name in multiple jars,
getResources gives you all the urls to theses resources.

In my case, I have a marker file in each jar, let's call it "marker.properties".
With getResources("marker.properties") I'm supposed to get all of them, not only the first one as with getResource().

In current implementation, you find only the resources located in the same jar as the class that called getResources.

To reproduce the problem, just have JBoss load 2 jars, for exemple by adding those 2 jars in the classpath of a xxx-service.xml
