Why don't go to Spring website?

I have some experience in Spring but not in JSF. So I can tell you JSF background is not required to learn Spring.
People in my team prefer using Spring over JSF because I think Spring is more powerful and flexible.
I do not have experience in JSF so other guys would tell you the comparision of the both.

Thanks guys for sharing your experience on Maven.

I prefer using Ant for my small to medium projects. I wanted to move to Maven, however I stopped at first place when reading Maven tutorials, as I did not understand what the document says. It seems that learning Maven is harder then Ant.

Will Maven replace Ant or both are still living together?

The question which I am going to post here was posted on Oracle Java forum about 2 weeks ago. However I did not get any answer so please allow me to re-post it here. Hope some experienced guys can help me.

Many thanks,

Hi Foamy Caramel,

I think you should use a common action listener if all the buttons do the same thing, regardless of buttons.
I prefer using separate action listeners for each buttons, and wrap the common things into a method.

If you call super() explicitly, it must be the first line in the constructor, otherwise the compiler will complain.
