Hello,
Hi!
I am really new to Tapestry, I just want to ask some questions before I
embark deeper with the framework (although I like T5 already)
Welcome! :)
However, with Tapestry it seems that the page is rendered from the
server side (which is pretty cool--like PHP)
Absolutely right. I wouldn't compare Tapestry and PHP because one is a
framework based on Java and the other is a programming language but yes,
HTML rendered server-side.
So I wonder, how to deal with components with T5?
Quite easy. Create a class in the components page, create a template for
it (optional, but very typical). You can also create CSS and JavaScript
files specifically for it and make Tapestry include them automatically by
using the @Import annotation.
GWT and Tapestry are veeeeeeeeeeeeeeeeeeeeeeeeeeeeeery different
frameworks. GWT is single-page and basically a client-side whole webapp in
a single page, but provides hooks to communicate with server-side things.
Tapestry is multi-page and basically server-side, but provides some
JavaScript things and hooks to client-side code.
In GWT I can create a simple button and some textbox to create a form,
style it with CSS. Add some handlers to get text inputs and pass it on
to the server.
Same for Tapestry, but implemented in a very different way.
With GWT create the whole web application by defining EntryPoints which
is a rendered page,
Tapestry is completely different in this case. There are no entry points:
instead, you have pages and, for some specific cases, dispatchers.
which contains components I can style with CSS and add function on the
page that will pass data back and forth the UI and the server.
Same for Tapestry, but implemented in a very different way.
Can I create my own components and forms with my own CSS
Yes! ;) In Tapestry, creating components is so easy you do that all the
time.
Check Tapestry JumpStart
(http://jumpstart.doublenegative.com.au/jumpstart/), specially the
Creating Components section, and Tapestry Magic
