Jarek Gawor commented on AXIS2-4279:
------------------------------------
Detelin,
I don't. I think we should restrict what types of files can be served using
?xsd or ?wsdl2. And we can't also allow any files to be served from within the
META-INF. That's a classloader lookup so technically anything within META-INF
anywhere in the classloader could be served, so we need to restrict it somehow.
I chose to restrict it based on the file extension.
Item 2 you mentioned is already how things work for ?xsd. That is, it looks for
schemas in a map first (this map is based on the service referenced wsdl/schema
files) but if it fails it falls back to this classloader lookup. That's why my
initial reaction was to remove this fallback code but at the end I decided to
keep and patch it, in case somebody is actually relying on that. I figured it
was added for a reason.
The ?wsdl2 also has this classloader lookup but it's the only means of getting
named wsdl2 files. So we would need a new solution for that if we were to
remove the classloader lookup code.
