Take a look at AjaxSwing. It is a web deployment platform for Java Swing applications. It allows companies that built Java desktop applications to run them as web applications. Because it produces pure HTML/JavaScript you can also run Swing application on iPhone, iPad and Android phones.

What can be reused depends upon your architecture. Look at Wicket, which offers a programming model very similar to Swing. That would not avoid rewriting of the GUI but makes the "mental mapping" easy.

If I'm getting it correctly, you need to reuse a database connection code. In that case:

You need to remove only the code that references Swing components. The ones that start with J. More accurately - the ones that are in package javax.swing or java.awt. The rest of the code can stay.

However, if your database connectivity code is too coupled to the GUI code, you'd better start that from scratch and just copy-paste of the parts in your Swings application.

In case you have a big Swing application, then you might want to use an automatic converter to web (ajax) application instead.

One such solution is AjaxSwing. There may exist others as well.

Check GWT, its a great framework that allows you to code in java...

You can turn your swing application into an applet, then it will run in a web browser, provided a JRE is installed on the client machine.

It will partly depend on how well you've structured your application. If there's no layering involved - if the GUI classes connect directly to the database, for example, then yes, you'll need to rewrite the whole thing.

If, however, you already have a separate data access layer, business logic layer and presentation layer, then you may only need to completely rewrite the presentation layer - while checking the other layers for things like concurrency safety.

The stateless nature of web applications - aside from session-based state - may mean you need to redesign the application significantly, of course. This may in turn mean that your existing "backend" layers aren't quite appropriate. While the theory is that they'd be presentation-layer-neutral, in my experience it would be quite unusual to manage to write an app targeting a single UI technology without some of the usage assumptions leaking through into underlying layers.

If you want a Swing like application on the web, you can use an Applet.

Yes you need to replace all the GUI layer with web-app stuff (jsps, controllers etc). It should be relatively easy if you kept the business layer separated from the GUI layer. I suggest taking a look at Spring Framework, it is very useful for developing web apps.
