[AXIS2/Java 1.2] xPath.selectSingleNode(element) does not return an OMElement when used on OpenVMS from a AXIS2 webservice but works on OpenVMS client code

[Stadelmann Josef <jo...@axa-winterthur.ch>]

Hi AXIOMXPath Experts,

	I use Axis2 1.2 on Topy of Tomcat on top of JDK 1.4.2-n both Windows and OpenVMS
	(I know I migth have to upgrade AXIS2/Java, see environment below)

	my routine getUsername(element) runs nicely from an Axis2SOAPClient on Window 2000 and OpenVMS

	The exact same code dose however NOT run when used on OpenVMS in our SpezplaService (Axis2/Java web service.)
	See correct launch/deployment below

	The statement 
	OMElement user = (OMElement) xPath.selectSingleNode(element);
	always returns NULL to user

	The element in which we seek the xPath (expression) looks identical, at least I can not see a difference.
	element.toString shown below

	The thing which botters me a bit is, that when I convert the received OMElement to a string within
	AXIS2/Java SpezplaService.login(), I can see an escaping technique used for each xmlns uri.

	Migth this be the reason why xPath.selectSingleNode(element); does not find what I want and returns no OMElement ??????
	In short loking at the xPath added name spaces they look the same on client and server but
	what if this name spaces are not not found due to some escaping technices used internal of the OMElement?

	my element up on which I try to seek for USERNAME

            System.out.println("Unknown Java exception at SpezplaService.getUsername()");
        }
        return "";


my environment looks like that: on OpenVMS

NOTE: I can not use JDK 1.5.0 due to beeing unable to use JPDA connector to debug from 
NetBeans IDE (need to attache to my web service)

Tomcat listens on port 8000 for a NetBeans IDE debugger attache request
