Most servlet engines do not provide implementations of
URLStreamHandler for the URLs they return... they simply return a
stream handler for FileURLConnection, or JarURLConnection.
If you look at a normal implementation of FileURLConnection it
doesn't have a method for getting the content type... only an
implementation of getInputStream()
This is poor I agree.
My own engine (GNU-Paperclips) implements it's own URLStreamHandlers
for this very reason.
Another problem with non-specialized URLStreamHandlers is the poor
WAR file handling, that's why most engines require that the WAR be
unpacked before use.
There is a way round this. You can implement your own
URLStreamHandler for the file: protocol and specify it when you start
the engine (with a system property). If you want to know how to do
that ask me privately.
