XSLT problem w/ ora:getProcessVersion

Question

I am running version 10.1.3.3.
I am using a BPEL XPath extension function in a Transform activity in a BPEL process. I open the XSLT Designer, select "Advanced Functions", and choose "xpath-expression" from the component pallette.
With the cursor in the "XPath Expression" field, I hit "ctrl-space" to select ora:getProcessVersion. I save my XSLT doc, and deploy my BPEL service to my server.
When my process runs, I get the following in my log:
XML-22016: (Error) Extension function namespace should start with 'http://www.oracle.com/XSL/Transform/java/'.
I am allowing the editor to create the namespace for the XPath expression. How do I fix this?

Answer 1

XSL w/ function:
<ns0:SourceProcess>
<ns0:DomainId>
<xsl:value-of select="ora:getDomainId()"/>
</ns0:DomainId>
<ns0:ProcessId>
<xsl:value-of select="ora:getProcessId()"/>
</ns0:ProcessId>
<ns0:ProcessVersion>
<xsl:value-of select="ora:getProcessVersion()"/>
</ns0:ProcessVersion>
<ns0:ProcessURL>
<xsl:value-of select="ora:getProcessURL()"/>
</ns0:ProcessURL>
<ns0:InstanceId>
<xsl:value-of select="ora:getInstanceId()"/>
</ns0:InstanceId>
</ns0:SourceProcess>
