Rich UI in general and EGL Rich UI in particular is a different animal 
than any of the thin client server-side technologies such as JSP Model 2 
(implemented in EGL via JSF) or any of the scripting languages.  With 
all server-side techniques the page is formatted on the host and then 
sent to the browser.  That's why server-side languages are historically 
terrible at rich client; at the end of the day, you still have to do 
most of the work on the server.

EGL Rich UI is entirely different.  You use the standard EGL syntax you 
learned for server-side, but rather than generating a Java servlet which 
in turn generates HTML (with some embedded JavaScript for a "rich lite" 
experience), the tool generates a complete JavaScript application which 
runs in the browser on the client and only goes to the server when it 
needs data.

The beauty of this approach is that it can incorporate *any other 
technology*.  If you have a well-behaved PHP script, you can call it 
from an EGL Rich UI client.  Or a SOAP service - written in RPG-CGI, if 
you desire.  Or of course a server-side EGL web app.  This also includes 
things like Google and with a simple HTTP proxy you can even call 
outside services.

It's a complete paradigm shift, and as far beyond server-side scripting 
as ILE is beyond RPG III.  That's one of the reasons I try to get people 
to ignore the scripting stuff; it's as out of date as Net.Data, and your 
time is better spent learning the new rich world of mashups and 
dashboards.  I hope I can get some examples up this summer; we'll see.
