Integrating Desktop Application to Web Application in Netbeans 6.5

Hi.
I'm trying to learn how to make my own web app and following those tutorials:
http://www.netbeans.org/kb/docs/java/gui-db.html
http://www.netbeans.org/kb/61/web/applets.html

I created a desktop application like showed in the first guide.
Then tried to integrate it into the Web Applet.

But for some reason after right clicking my desktopapp's java file and selecting "run" i do not get the html file like shown "Running an Applet Source File" part of the second tutorial. Is it because one is an applet and other is an applucation?

Then i make a jar file, import it into my new web application like showed in the second tutorial and then build and then run, but i get an error like that in my IE window.

And yes i change the package location and name in the import part to fit mine.

So now i have a question. Can I or can't I integrate a desktop application to a webapplication on not. If it is possible how can i do it in netbeans 6.5?

Thanks in advance
