Hi,
Both org.apache.commons.httpclient.URIException and import
org.apache.commons.httpclient.util.URIUtil are used by the URLFileName
class. And yes, VFS has a dependency on the Commons HttpClient library. Was
this your question?

Robert

Re: [VFS] Re: dependency on commons-httpclient? (was Re: vfs question)
Posted by Andy Lewis <aj...@ascii27.net>.
I believe the dependency exists due to a need for correct parsing of
URIs. There was an extended thread, and a great deal of testing and
changes to the code to make sure that all URI cases are handled
correctly, and in the end the commons-httpclient library was needed to
get it right. If I remember correctly this was viewed as the best way to
get correct behavior right now, even though it does introduce a pretty
heavy dependency and there is some hope (at least among some on the
thread) that eventually this dependency can be eliminated.
Not an official answer to anything, since I'm not a committer and have
yet to be able to contribute much of anything, but hopefully helpful.

"If you use WebDav, it is not mandatory because WebDav depends on it."
should have been...
"If you use WebDav, it is mandatory because WebDav depends on it."
Just a change in my train of thought from saying "not optional" to
"mandatory" and forgetting to drop the "not". Whoops!

[VFS] Re: dependency on commons-httpclient? (was Re: vfs
question)
Posted by Jacob Kjome <ho...@visi.com>.
Of course, commons-httpclient should be an *optional* dependency. If you
use WebDav, it is not mandatory because WebDav depends on it. But for
basic HTTP stuff, it should still be optional and fall back to using
URL.openConnection(). When commons-httpclient is available, it should give
you some extra functionality, that's all. If you are attempting to grab
something via an HTTP URL and VFS bombs out because it doesn't have
commons-httpclient in the classpath, I think that should be reported as a
bug. Maybe Mario can verify this?
