Think it would be useful to have following constructor

    public ServletRunner( InputStream webXml, File contextDirectory, String contextPath ) throws IOException, SAXException {
        _application = new WebApplication( HttpUnitUtils.newParser().parse( new InputSource( webXml ) ), contextDirectory, contextPath );
        completeInitialization( contextPath );
    }

I generate web.xml, its not a phyical file
