Re: Wicket and JEE6
Weld has wicket support built-in I believe.

RE: Wicket and JEE6

Warning: Long Response with sample code to illustrate issue.
I ran the following code in Glassfish v3 with the following jars:
portlet-api_2.0_spec-1.0.jar (someone is relying on this??)
slf4j-api-1.4.2.jar
slf4j-jdk14-1.4.2.jar
wicket-1.4.7.jar
Be sure to add an empty beans.xml to the WEB-INF folder.
After starting up Glassfish, type the following in the browser
(WicketTest is the name of my project, yours may vary):
localhost:8080/WicketTest/
The output it: No Util Class
localhost:8080/WicketTest/jsf.faces
The output is: Hello World!

I started a JSR-299 integration project a while back, but at the time
there
was no portable way (across vendors) to get to the stuff you needed to
inject into your components. I believe that's been fixed in the latest
API,
but I haven't had a chance to dig in and verify that and then use it.
My
guess is that there's really not that much to it (my code was pretty
small).

RE: Wicket and JEE6
Posted by "Ericksen, Mark W (IS)" <Ma...@ngc.com>.
Weld claims support, I don't know about built-in.
When I use @Inject in a Wicket WebPage subclass the objects are null.
Like I mentioned below, I added weld-wicket.jar and subclassed the
WeldApplication and the injected objects in the Wicket WebPage subclass
are still null.
This was from following this example:
http://docs.jboss.org/weld/reference/1.0.0/en-US/html/viewlayers.html
If you track down the example code it seems that the examples from JBoss
are using older versions of Wicket and Weld/Seam so I don't know if
something has broken in either project, wicket or weld.
Injection worked like a charm in a JSF2 controller class so I don't know
what going wrong or what supporting jar is missing.
Any additional help is greatly appreciated!
-Mark
