Loading .properties files in JRun4

Hello,

I'm using the echo2 web framework in my application. But trying to start it in JRun4 returns the following exception:

26/02 17:12:21 user Remote: init
26/02 17:12:22 error
[1]java.lang.NullPointerException
    at nextapp.echo2.app.util.PropertiesDiscovery.loadProperties(PropertiesDiscovery.java:67)

Echo2 uses .properties files to map the components to their peers.

The NPE occurres in the line with "in.close();" in the following function. Is there something configurable to ensure that JRun4 can open the stream to the properties files?

public static Map loadProperties(String resourceName, ClassLoader classLoader) 
throws IOException {
    Map propertyMap = new HashMap();
    Enumeration resources = classLoader.getResources(resourceName);
    while (resources.hasMoreElements()) {
        URL resourceUrl = (URL) resources.nextElement();
        Properties peerProperties = new Properties();
        InputStream in = resourceUrl.openStream();
        try {
            peerProperties.load(in);
            propertyMap.putAll(peerProperties);
        } finally {
            in.close();
        }
    }
    return propertyMap;
}

Or any other idea what I can do to get it running?

Thanks.
