Re: Annotations and ComponentRequestFilter Problem
Hi Taha, Hi Thiago, Thanks a lot for your reply, it's working perfectly! And besides, this surely gave me some more basic understanding on how tapestry works.

Hi,
i'm having a problem using custom annotations and a ComponentRequestFilter.
I am defining my own class annotation (TestAnnotation) and a test class
(Index) that uses this annotation.
In my ComponentRequestFilter however, when i am checking the page class
(via
componentSource.getPage().getClass(), it doesn't have the annotation.
However, When i try to read the annotation on the class itself (using
Index.class), it's working.
Therefore i assume this has something to do with class transformation in
tapestry, it seems like the class annotation isn't present in the
transformed class anymore.
I have of course read the article at
http://tapestryjava.blogspot.com/2009/12/securing-tapestry-pages-with.html
,
and i can't see any difference:
Component page = componentSource.getPage(pageName);
if (! page.getClass().isAnnotationPresent(RequiresLogin.class)) {
return false;
}
is exactly what I'm using (except for the different variable names...), it
just doesn't work.
When i try
Index.class.isAnnotationPresent(TestAnnotation.class)
it returns true, just as expected.
If anyone got a good idea, i'd be very thankful.
Regards,
Sascha

This doesn't work if you add the annotation after you started the
application. Another way of doing that, which works well with live class
reloading (you add, remove or change an annotation and it automatically
works) is using a worker. This is the one which handles the @Secure
annotation in Tapestry:
public class SecureWorker implements ComponentClassTransformWorker
{
public void transform(ClassTransformation transformation,
MutableComponentModel model)
{
Secure secure = transformation.getAnnotation(Secure.class);
if (secure != null)
model.setMeta(MetaDataConstants.SECURE_PAGE, true);
}
}
You can get the ComponentModel of a given page or component instance using
getComponentResources().getComponentModel().

Re: Annotations and ComponentRequestFilter Problem
Hi taha, you can find an example project here: http://satansoft.de/tapestry/annotationtest.zip It uses a very simple setup to show the problem. In TestFilter.java in the annotationTest() method you can see that the upper test case is not working, but the lower case is working well.

Re: Annotations and ComponentRequestFilter Problem
Hi Thiago, thanks for your reply. I will certainly give that a try, but i won't be in the office until monday. I'm not sure, if i stated my problem right (as i'm quite new to tapestry). I am not dynamically adding the annotation to the class, as far as i can see, so getting it from the component source should work, shouldn't it? There is a test project that desscribes the problem, it can be found at http://satansoft.de/tapestry/annotationtest.zip. In the TestFilter class you can see how i try to get the annotation from the page. Btw, i'm using Tapestry 5.2...

Re: Annotations and ComponentRequestFilter Problem
Just move the annotation out of the pages package. Although I don't know the internals of tapestry that well but I think because pages and components packages have live reloading they may be loaded from different classloaders... regards Taha On Fri, Oct 22, 2010 at 7:19 PM, shinlang sascha.hinl...@gameforge.dewrote: Hi Thiago, thanks for your reply.

The binding declaration was wrong...

RE: annotations
You don't need an empty spec, but you do need to tell tapestry where to find your page/component classes. In your application file: application meta key=org.apache.tapestry.page-class-packages value=com.myco.web.page/ meta key=org.apache.tapestry.component-class-packages value=com.myco.web.component/ /application So, tapestry will look in those packages for pages/components. Hope that helps.
