URIResolver base for document()

[stephen <st...@yorksignal.org>]

I am using Xalan in an HttpServlet to transform Documents created on the fly. I
wrote a URIResolver to pull the templates from the Servlet context
(ServletConfig.getServletContext().getResourceAsStream()). My resolver works
perfectly for xsl:includes. The calls to MyURIResolver for the includes in the
base template has a null base. I assign a base to the Sources I return via
Source.setSystemId() as appropriate. However, any uses of document() result in a
call to resolve() with a base of the directory from which java was called
prefixing the base I expect.

For example, with this war:
myapp.war/
  xslt/
    default.xsl
    include/
      fun.xsl
      data/
        fundata.xml

And this code:
Source source = new DOMSource( myDocument );
Source xslt = new StreamSource( myURIResolver.resolve( "default.xsl", null ) );
myTransformerFactory.setURIResolver( myURIResolver );
myTransformerFactor.newTransformer( xslt ).transform( source,
  new StreamResult( someOutputStream ) );

default.xsl has
  <xsl:include href="include/fun.xsl" />
which results in resolve( "include/fun.xsl", null )
my URIResolver returns a Source with fun.xsl, and a base of "include/".

fun.xsl has
  document('data/fundata.xml')
which results in resolve( "data/fundata.xml", "file:///opt/jboss/bin/include/" )
Obviously, what I want is resolve( "data/fundata.xml" "include/" ).

Where exactly is the "file:///opt/jboss/bin/" coming from, and how do I set
something else instead?
