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.
Yah, that's what I mean. However I am not sure if with Tapestry I can
implement a way to process URL parameters such that the rendered page is
based on the URL parameter, like: http://mypage.com/user123 where,
user123 is a user id that is when accessed the rendered page will be
the user page. Something like that.
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.
I see, thanks for the tip. Do you mean in the package where Layout.java
is located?
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.
I am not really used to server-side page, but I am trying to catch the
idea.
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.
I see, anyway, what I mean by that is the loose-coupling of the UI
element to the server side function ("services"). I hope Tapestry UI
elements, although server-side, is loosely couple with "services"
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
(http://tawus.wordpress.com/) for examples.
This is cool:
http://jumpstart.doublenegative.com.au/jumpstart/examples/component/creatingcomponents
However, where do I place the CSS? In the .tml file? Or somewhere else?
Thanks for the ideas.
