What's wrong with this source ??

[Matthias Schiffer <sc...@web.de>]

public void start_Tomcat() {
                 myLibPath = System.getProperty("ICCS_LIB_PATH");
                 File app = new File(myLibPath);
                 myLibPath = app.getAbsolutePath();
                 File app1 = new File(myLibPath);
                 System.setProperty("catalina.home", app1.getParent());
                 myTomcat = new Embedded();
                 Engine engine =
myTomcat.createEngine();                 Host host = 
myTomcat.createHost(C_CanonicalHostName,app1.getParent());
                 engine.addChild(host);
                 Context ctx =
myTomcat.createContext("",app1.getParent());
                 ctx.addWelcomeFile("index.html");
                 ctx.setDocBase(app1.getParent());
                 System.out.println(ctx.getDocBase() + " , " +
ctx.getPath());
                 host.addChild(ctx);
                 myTomcat.addEngine(engine);
                 Connector connector = null ;
                 myTomcat.setUseNaming(true) ;
                 try{
                         connector =
                 
myTomcat.createConnector(InetAddress.getLocalHost(),8080,false);
                 }catch(UnknownHostException uhe) {
                         System.out.println("Exception: " + uhe);
                 }
                 myTomcat.addConnector(connector);
                 try{
                         myTomcat.start();
                 }catch(LifecycleException lce) {
                         System.out.println("Exception: " + lce);
                 }

So, when you read this source, I think the DocBase is the directory
where Tomcat searches for HTML files, but it does not although it is
listening..
What further do I have to set ?? Please Help Me. Thanks!
