Hello Prabhaker,

I am a novice at java. I have come from the mainframe programming arena (specifically MUMPS or M)

Java is definitely on the opposite side of the spectrum.

Now that I am learning java, (and it has been a struggle,)what is different in AJAX and how much longer will it take me to finally tweak my brain to incorporate this too. Thanks for your input.

Hello Prabhakar:

Since GWT is the framework used by Google for their AJAX applications, I think that you can address a question that I have about AJAX itself.

It is great to have gtalk inside the gmail window without software installing, but, once I had a sniffer record the traffic with only gmail opened in firefox, and it goes up to 500 request per minute. Well, suppose that I have gmail open for about 4 hours and thanks to heaven nobody talks or write to me in that time, and I can work... there you have 120K wasted requests. Now, if AJAX has the success that it appears it will, multiply by the 1000 million potential users of the internet... here you have 120E10 wasted requests...

1 request = 2k? (for the minimum of the Ethernet Packet)

mmm, about 24.5 terabytes of wasted bandwidth... in 4 hours...

Don't you think that a bright student of a third world country can use a little bit of that bandwidth?? Can you waste it just because you want to "mimic" desktop behavior with awesome technology (GWT-AJAX) over a request response based protocol??? Does the internet infrastructure even support that load?

IMHO we should make Desktop Apps and let the web for the no interactive reports.

Thanks in advance for the response.

Hello Prabhakar,
I just wanted to know some scenarios where normal submission of page using the conventional way (like clicking of button,hyperlink etc), would be a better option than using Ajax.


Thank you

Hello Prabhakar,

How can I extend GWT in order to include additional libraries to it. Doues your book address this issue?

GWT uses the concept of modules for packaging and using functionality. In thi book we create two custom widgets - calendar and weather, and use them in a separate project.

Your thoughts are revolutionary.

I just wonder why it went so silently.

Perhaps because it's obviously a troll that makes no sense?
