Hello,

Could you give thumbnail sketch comparing these three?
I'm trying to sway the brass to move to web 2.0 - if you could give a helicopter view on this it would be appreciated.

Thanks
Don

All three are great for user interfaces. I'm sure you can create equally good UI's with any.

GWT however is in a different category. Although it does do Ajaxy user interfaces it is more than just a user interface library. It aims to provide many tools to bring real software engineering to Ajax applications. I think it accomplishes this well.

If I were to draw a sketch it would simply be three columns, one for each technology. Each would have a box in their column for user interface. GWT would have additional boxes for:
- server interoperation (HTTP, XML, JSON, GWT RPC)
- internationalization
- code obfuscation
- code optimization
- automatically cross browser (even the code you write)
- unit testing
- eclipse (or any Java IDE)
- modularization and java organization/OOP
- easy application versioning
- performance (image bundles, caching considerations)
- code generation

There's quite a bit. Also the GWT engineers are great and constantly working on improving the compiler which means your code automatically runs better with new releases.
