Error initializing reports service

Hi,

I'm trying to fetch resource, attached to report, using BIRT like this:

URL url = reportContext.getResource("conifg.xml");

            if (url == null)

            	out.append("No config.xml file");

            try {

    			BufferedReader in = new BufferedReader(

    			        new InputStreamReader(

    			        url.openStream()));



    			  String inputLine;



    			  while ((inputLine = in.readLine()) != null)

    				  out.append(inputLine);



    			  in.close();

    			  

    		} catch (IOException e) {

    			e.printStackTrace();

    			StringWriter sw = new StringWriter();

    			e.printStackTrace(new PrintWriter(sw));

    			String stacktrace = sw.toString();

    			out.append(e.toString());

    			out.append(stacktrace);

    		}

This code cause following stacktrace:
