[DUG] AJAX libraries for Delphi

[John Bird]

Recommendations??  

Eg anyone use Google Web Toolkit?

http://code.google.com./webtoolkit/

Guff:

"Google Web Toolkit (GWT) is a Java software development framework that
makes writing AJAX applications like Google Maps and Gmail easy for
developers who don't speak browser quirks as a second language. Writing
dynamic web applications today is a tedious and error-prone process; you
spend 90% of your time working around subtle incompatibilities between web
browsers and platforms, and JavaScript's lack of modularity makes sharing,
testing, and reusing AJAX components difficult and fragile.

GWT lets you avoid many of these headaches while offering your users the
same dynamic, standards-compliant experience. You write your front end in
the Java programming language, and the GWT compiler converts your Java
classes to browser-compliant JavaScript and HTML."

Aren't you using a library? Under Java I use DWR - which deals with all the
issues surrounding IE/Firefox incompatibilities. 

Are there any around that people are using for Delphi? Typically they create
you Javascript classes to call from your Delphi source code. So you just
create the object (with a mapper file on your web server) and call the
method and the infrastructure takes care of all the rest. 

I implemented a file upload using AJAX that _accurately_ tells you how far
through the upload you are using AJAX (it asks the server how much of the
file you have uploaded). It really makes uploading via HTTP fantastic!

Agreed. IE is consistently the biggest factor in the time it takes me to
make a web app.

In fact I'm struggling right now with an IE problem that should work fine
(using xmlHttpRequest) but doesn't (works fine in Firefox etc).
*sigh*
