Puzzling problem with express app

app.js

global.app = express();
var staticDirectory = path.join(__dirname, 'public');
var debug = require('debug')('ExpressApp1');

app.enable('strict routing');
app.set('port', process.env.PORT || 3000);
app.set('env', 'development');

//var chatRouter = express.Router();

var jade = require('jade');

   
app.set('views', __dirname + '/chat/views');
app.set('view engine', 'jade');
app.set("view options", { layout: false });


var tw5serve = require(path.join( __dirname, 'TiddlyWiki5', 'webexpress.js'));
//app.all('/tw5/*', tw5serve('tw5', 'masterWiki'));
//app.all('/mktng/*', tw5serve('mktng', 'marketing'));
app.use('/arlen/*', tw5serve('arlen', 'arlen'));
