Ok, we've found the solution to the problem. It was indeed a namespace
issue, the following code excerpt works OK:
public Representation propfind(Representation data) throws
ResourceException {
List<DavProperty> reqDavProps = new ArrayList<DavProperty>();
if (data != null) {
try {
DomRepresentation reqXML = new DomRepresentation(data);
reqXML.setNamespaceAware(true);
reqXML.getNamespaces().put("d", Dav.DAVNS);
NodeList props = reqXML.getNodes("/d:propfind/d:prop/*");
Iterator<org.w3c.dom.Node> nit = props.iterator();
while (nit.hasNext()) {
org.w3c.dom.Node n = nit.next();
if (n.getNodeType() == org.w3c.dom.Node.ELEMENT_NODE) {
Element e = (Element) n;
reqDavProps.add(new
DavProperty(e.getNamespaceURI(), e.getTagName()));
}
}
getLogger().info(String.format("Requested DAV
properties: %s", reqDavProps));
} catch (Exception ex) {
ex.printStackTrace();
getLogger().warning(Localisation.getMessage("core.err.res.wksp.cont.propfind.bad.xml",
ex));
}
}
// Rest of the propfind handler here
}
Sorry if I have bothered you with this (non-)issue, and thanks for your support.
