problems with StreamSource and UNC

[daprodigy]

hello
in order to achieve a xml-validation, i have to generate a StreamSource-instance and that's exactly the problem. but first some details: the application is being developped on a winxppro-pc, but productively runs on a win2003-server. for reliable test runs, a win2003-server is running on the winxppro-host using vmware.

now back to the problem. 4 directories are configurable, where unc-pathes should be possible as well. these pathes are loaded with a PropertyHandler from a .properties-file.

i have written a test-class to locate the problem:

import java.net.*; 
import java.io.*; 
import javax.xml.transform.*; 
import javax.xml.validation.*; 
import javax.xml.transform.stream.StreamSource; 

public class URITest { 
        
    public static void main(String[] args){ 
        PropertyHandler pHandler = new PropertyHandler("C:\\props.properties"); 
        String xmlpath = ""; 
        try{ 
            xmlpath = pHandler.getStringProperty("xmlpath"); 
        } 
        catch(Exception e){ 
            System.out.println("ERROR1: " + e.getMessage()); 
        }        
        
        String xsdPath = "C:\\test.xsd";    
        try{ 
            SchemaFactory factory = SchemaFactory.newInstance("http://www.w3.org/2001/XMLSchema");        
            File schemaLocation = new File(xsdPath); 
            Schema schema = factory.newSchema(schemaLocation); 
            Validator validator = schema.newValidator(); 
            Source source = new StreamSource(xmlpath + File.separator + "test.xml"); 
            validator.validate(source); 
            System.out.println("end of procedure"); 
        } 
        catch(Exception e){ 
            System.out.println("ERROR2: " + e.getMessage()); 
        } 
    }    
}

test 1:
host: winxppro
user.dir: D:\Projekte\URITest2\dist
content of properties-file: xmlpath=\\\\Srvfile\\usermag\\test

output:
end of procedure ... all right, xml-file was found

test 2:
host: win2003server
user.dir: D:\uri
content of properties-file: xmlpath=\\\\localhost\\testsharing\\temp\\POLOPDF

output:
ERROR2: D:\uri\localhost\testsharing\temp\POLOPDF\test.xml (The system cannot find the path specified)

for some reason, the xml-path is seen relative to the working-dir. the result is an ioexception because the file wasn't found.

do somebody have an idea what's the problem and why the hell the 2 systems aren't working similar?

thx a lot!
