XOM API for Processing XML with Java

[Nils_Kilden-Pedersen AT Countrywide.Com]

Shouldn't you filename be:
"file://C:/temp/wurfl.xml" ?
It believes that c: is the protocol.

        Subject:        [XOM-interest] XOM problem with servlets


Elliotte,

I am working on the WURFL library. What I see is that while I can use XOM
no problem in a command line test application, I get an error when I 
start the parsing
from within a servlet:

Here is the servlet line that gives a problem,
 
    UAManager uam = ObjectsManager.getUAManagerInstance();

which invokes:

     public static UAManager getUAManagerInstance() throws IOException {
        synchronized (lock) {
            if (wurflInstance==null)
                wurflInstance = new Wurfl ();
            if (UAManagerInstance==null)
                  UAManagerInstance = new UAManager(wurflInstance);
                return UAManagerInstance;
           }
      }

which invokes:

 
    Wurfl() throws IOException {
        this("C:/temp/wurfl.xml");
    }
 
which invokes:

    Wurfl(String fileName) throws IOException {
 
        try {
            Builder parser = new Builder();
            Document doc = parser.build(fileName);
            //System.out.println("Wurfl: parsing "+ fileName + " 
succesful!");

            //String rootname = root.getLocalName();
            //System.out.print(rootname);
            Element root = doc.getRootElement();
            Element devices_elem = root.getFirstChildElement("devices");
           :

here is the error I get. Any idea?  thank you -luca
