Need help in deciding which Java technology to choose

[Nir]

Hi,
I'm a .Net programmer who needs to convert existing applications to
Java.
I have two types of applications:
1. Simple 1-page applications, that read xml files, change xml files,
and display HTML pages to the user.
2. More complex applications that use a web service to get data,
display it to the user, and then call the web service to alter data in
the database.

My question is, given the plethora of information in this course, is
there a specific lesson I should pick up on? I mean, the simple
applications seem to be fit for simple JSP pages, but is there a more
suitable technology for the more complex applications? JSF, for
example?

I'd be happy to get your comments!
Thanks a lot,
Nir

When I first started using Java for web development, I used only JSP.
They were easy to learn and had the flexibility where I could hack
together scriplets and a such to create fairly dynamic sites without
having to learn too much about servlets and other technologies.

As I learned more, I then added layers to what I was doing. I began
using servlets to manage user access. I used JSF to display and
update data. I dabbled with Hibernate on ORM, but don't get me
started on that.

I think JSP would be a great place to start. Maybe then create some
backing beans to manage your data. As you get into more dynamic
interfaces, add JSF and AJAX into the mix.

Java has good XML support.

Java has good web service support if you pick an IDE that can
do some of the stub generation for you (similar to VS add web
reference).

JSP pages are quite easy to start with. At least if you can live
with scriptlet code (<% %>).

JSF is probably the closest you will get to the ASP.NET
programming model.

But JSF do take an effort to learn (more than ASP.NET !). But if
you get a good book, then you can do it.
