Web application design (frameworks) help

[logadsos]

Hi,

I am familiar with java servlets, jsp and html / css / javascript, but not
with any additional libraries out there. I want to build an application
processing quite a lot of information (financial) so it needs to be distributed
on several servers. The frontend would need to be something nice - I was
thinking about GWT-EXT. But then - I have no experience with it and don't
know if it would be difficult to achieve that only with it ? And then I was
thinking about Spring together with GWT-EXT. The thing is that I need it to be
flexible in terms of what happens if the application suddenly grows really big
and will need to deal with lots of database transactions. Also - the possibility
to keep consistent and reusable UIs (like widgets) which is easy to debug / test. Any information is welcomed.

Thanks.

If you have experience with Java, then GWT is a good choice. It uses a set of Java libraries and it provides ready to use widgets that you can also customise if want to. Also, it is quite easy to learn, the tutorial on the Google Web site it s really comprehensive.

I ve never used Spring, but I know it is quite powerful. Besides, if you have to handle large amount of data, an enterprise solution such this seems the right one.

Hi,

Thanks for your reply - I thought no one was going to respond :)
Yes - I have few years of java experience and I have already
looked at GWT design - personally I like it a lot but wanted to make sure
that people had some expieriences with it and they can recommend it
for such project. Also I found few ways of integrating spring with GWT - not
chekced it yet but looks promising.

Thanks a lot !
