XOM API for Processing XML with Java

[luca passani <passani AT eunet.no>]

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
