See the overview page of the API documentation.

Odd. This almost sounds like the protocol handler isn't being
initialized. But I don't see how that can be. The prococol handler is
initialize in a static block in jcifs.Config. And NetworkExplorer.init
and SmbFile use jcifs.Config. Unless ... jcifs.util.Config is creating
ambiguity.

Can you put

  Class.forName( "jcifs.Config" );

at the beginning of NetworkExplorer.init()? To rebuild the jar you will
need to append 'http' to smb target on line 41 of build.xml and do an
'ant jar' (assuming you have ant).

How do I install these web.xml files? Where do they go? I've been editing
conf/resin.conf!

A  program should be written to model the concepts of the task it
performs rather than the physical world or a process because this
maximizes  the  potential  for it to be applied to tasks that are
conceptually  similar and, more important, to tasks that have not
yet been conceived.
