Thank you Henry, that worked. (i don't have it in endorsed, btw) But having
done that it still results in a NullPtrException the same as when i used new
XPatchFactoryImpl, here
because the dtm is null, HERE
public void setRoot(int root)
{
// %OPT% Get this directly from the lpi.
XPathContext xctxt = wi().getXPathContext();
m_dtm = xctxt.getDTM(root);
m_traverser = m_dtm.getAxisTraverser(m_axis); /* HERE m_dtm is null */
m_isFresh = true;
m_foundLast = false;
m_root = root;
m_currentNode = root;
if (DTM.NULL == root)
{
throw new RuntimeException(
XSLMessages.createXPATHMessage(XPATHErrorResources.ER_SETTING_WALKER_ROOT_TO_NULL,
null)); //"\n !!!! Error! Setting the root of a walker to null!!!");
}
resetProximityPositions();
}

XPathFactory allows for different factories based on the input data model. I
believe the actual system property you set should be:
System.setProperty("javax.xml.xpath.XPathFactory:"
+XPathConstants.DOM_OBJECT_MODEL,
"org.apache.xpath.jaxp.XPathFactoryImpl");
Also, is xalan.jar merely on your class path or have you used the Java
endorsed standards override mechanism? See [1] for more information.
Thanks,
Henry
