Using xsl document function in transform xsl

Question

I'm trying to use an external xml document in an xsl transform that's used in a Transform activity in an 11g BPEL process:
<xsl:variable name="plants" select="document('plantTransposeLookup.xml')/plants"/>
I need to load up the document to use it in a lookup to get replacement values for a key.
This works fine in JDev, but not when I deploy it to the server.
The error I get when I run it is:
The XPath expression failed to execute; the reason was: javax.xml.transform.TransformerException: XML-22021: (Error) Error parsing external document: 'no protocol: plantTransposeLookup.xml'.. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
I've also gotten:
The XPath expression failed to execute; the reason was: javax.xml.transform.TransformerException: XML-22021: (Error) Error parsing external document: 'Unsupported feature: 'document(''), when stylesheet built using InputStream, Reader'.
I've also tried using the ora:doc function:
<xsl:variable name="plants" select="ora:doc('plantTransposeLookup.xml', 'plants')"/>
......but this doesn't work in JDev and is also erroring off on the server with:
The XPath expression failed to execute; the reason was: javax.xml.transform.TransformerException: XML-22016: (Error) Extension function namespace should start with 'http://www.oracle.com/XSL/Transform/java/'.. Check the detailed root cause described in the exception message text and verify that the XPath query is correct.
Does anyone know how to actually import an xml doc into a mapper??? I must be doing something stupid.
Thanks for any help.

In OSB, document() function needs absolute path of the XML file. So if you want to access the XML document for lookup, you need to put the XML file on the server itself and use the path of the XML file.
Although this is not a correct approach for managing lookups in OSB. The resource of XML Document type are not to be used for such use cases. What you can do is create a XQuery which can server as DVM.
Here is an example on how to use DVMs in OSB:

If you dont want to use XQuery and want to rely only on XSLT, then within the same XSLT document create a separate template which can store all the lookup data.
