If you use Swing or AWT within a Java program, then these objects are
displayed on the machine that's running the Java program (if you choose to
display them...). You *can* access Swing and AWT from a servlet or JSP, but
if you use Swing or AWT to show a window (for example), then that window
would appear on the SERVER !!! Not the client...
As other people have suggested, if what you're trying to do is use Java GUI
components in the web browser, you have to make your servlet or JSP page
create and send the necessary HTML to create an Applet.
However, there are two main uses that I can think of for using AWT/Swing
with a servlet or a JSP:
1./
Use some AWT objects to access a Graphics (or Graphics2D) context to
dynamically generate graphics to send to the client. This would not be
within the servlet/jsp that generates HTML, but in a separate servlet/jsp.
For example, your main JSP/servlet could write some HTML like :
<img src="saleschart.jsp?x=100&y=100&month=8" />
(instead of src="saleschart.gif" ...)
Then saleschart.jsp would receive a request, draw an image based on request
parameters, set the correct HTTP content-type header (such as "image/png"),
and send that back to the client. Dynamic graphics!
2./
Display a window on the server for your application, allowing you to modify
the site's configuration in realtime. For example, imagine your web
application has a static class containing, say, database connection
parameters, or paths to some XSLT templates... by providing a server-side
window, the administrator could access the running application via a GUI
instead of a web interface. Think about it, it's VERY useful... ;-)
