Local to the side interpreting the job? Yes, of course, though it should
be prefixed by 'file:', like this: file:/home/user/directory/file.sh

Files on the system composing the JSDL document are another matter. The
problem is just because you name a thing doesn't mean that the other end
knows what to do to access it. There are a number of workarounds for
this, e.g. starting a local http or ftp server, etc. Two of the most
interesting things you can do though are cid: and data: URI types, which
allow you respectively to either transfer the data as an attachment to
the message conveying the JSDL document or directly embedded within the
document (respectively).

References:
   RFC 1630 <URI:http://www.ietf.org/rfc/rfc1630.txt> includes the
       definition of the cid uri type.
   RFC 2397 <URI:http://www.ietf.org/rfc/rfc2397.txt> defines the data
       uri type.
