Re: [ANNOUNCEMENT] New Tapestry 5 book
Hi Igor, I bought the PDF Book today and started reading immediately, very well written so far looks very promising! But where can I get the content (examples) that will be delivered on CD with the printed version? thx, Max Am 16.09.2009 um 20:28 schrieb Igor Drobiazko: Hello folks, I am pleased to announce a new Tapestry 5 book. The book is written in German and is available as eBook on publisher's website: http://www.addison-wesley.de/main/main.asp?page=home/bookdetailsProductID=174975 The hardcover version of the book will be available starting from Sep 28 2009. I'll make another announcement when the hardcover version is released. Among other things the book covers : * Getting Started with Tapestry 5 * Concepts of the framework * Localization/internationalization * Creating Forms * Generation of user interfaces for JavaBeans * Writing own components and mixins * Ajax * Writing tests for Tapestry applications * Hibernate and Spring integration * Dependency Injection and Tapestry IoC * AOP and bytecode manipuation Special thanks go to Howard and Ulrich Stärk. Howard gave me some hints on how to write a better book and wrote a foreword. Ulrich was responsible for the technical review of the book and helped me to improve the quality.

SecurityContextHolder is the class that interacts with threadlocal:
public class SecurityContextHolder {
private static ThreadLocalSecurityContext tLocal = new
ThreadLocalSecurityContext();
public static void set(SecurityContext securityContext) {
tLocal.set(securityContext);
}
public static SecurityContext get() {
return tLocal.get();
}
public static void remove() {
tLocal.remove();
}
}
U can get the SecurityContext during the thread execution with:
SecurityContextHolder.get()
Let me know if u need something else

But where and when do you set the ThreadLocal? It must be set on
every
request (each request is another thread...)
Do you have a common base class where you handle this? Any other
way you do
it?

Hey Max, I had a similar problem and at the end create an object in
the ThreadLocal that contains a SecurityContext with the user
information (very lightweight object). The idea was taken from
Spring-Security. This way u have access to the user in the execution
thread. It was kind of weird for me to be accessing the
HttpSession in
all the layers of the application.

I already set the creation and modification date in each entity.

This information (the user) is in an SSO (WebUser in my case) but

There is a method called getEntity().

All,
I know Java and have been using pure Java frameworks like ZK and
Echo2 to
develop web applications. I don't know anything about JavaScript,
and have
been trying to learn T5 in the hope of creating a real application.
However,
it appears that with T5 I am not completely shielded from JavaScript
(may be
I can do this in pure Java?) if I want to do AJAX. The specific
example that
I want to implement is the classic 2 dropdown - the second one
dependent on
the first one. So let's say you select a country, and the in the
second
dropdown, the list of states/provinces is updated to match what is
available
for the country selected in the first dropdown.
From the forums, I have gathered that I must use the Chenille Kit
onEvent
mixin to make this happen. I also saw some sample codes in the
forums that
appear to solve this exact issue. The problem is that I don't know
where to
put this code (in Java file or tml file or some other js file) and
then how
to tie these things together. In the T5 help documentation, there is
some
info about using RenderSupport for this. Again, the code given is only
snippets with no complete example that I can download/copy. I could
not
understand this documentation at all.
So my question is simple: where should this code be located and how
are all
these things connected? Is there anything else that needs to be
added - such
as RenderSupport (and where)?
