Flex4 in action - queries

Hi Authors,

I have not worked in Flex but just heard of it as it is fully into Rich UI and useful for developing RIA.

I have couple of queries.

1. Is this a beginners book?

2. What would be your justification towards going for Flex when I have other alternatives in web technologies/frameworks like Struts, Spring etc? I am a Java EE guy.

3. Out of its advantages what flex claims it has, is not a heavy stuff when I get out my page when i view it? How flex manages that heavy nature of all GUI components? The more beautificaiton I need in terms of functionalities and presentation, the more heavy my application will become. Right? I may be wrong but this is what my perception says.

Thanks,
Raghavan alias Saravanan M

These are not really comparable. Flex is an RIA technology, Struts is a web application framework - what you are comparing there is whether to go for a RIA or a plain old HTML application. Spring is an "enterprise" framework (for want of a better term) - its not comparable to Flex at all.

Hi Paul,

Thanks. Thats what I had mentioned as well that I may be wrong in my perception.

However, overall how exactly the heavy nature of the components is getting addressed?

What do you mean by "heavy nature"?

I agree with Paul in regard to comparison with struts, spring, etc.... different tools for different purposes.

As far as it being a beginners book, the first section of the book is for people who are new to Flex 4, whereas the 2nd and 3rd sections deal with more advanced concepts.

Hi Paul,

I have an understanding the RIA comes with the thick clients. Having said that the components would be heavy in nature with all sorts of required things wired together internally. In this case, the page being loaded would be heavy and so the response time.

First of all, am I right in saying this definition? If so, how does Flex address this?

Thanks.

Thanks Dan. I agree. My perception was incorrect!
