Can you try adding a protected or public zero-arg constructor for
ArticleListBuilder?
public class ArticleListBuilder {
protected ArticleListBuilder()
{
}
...
}
The scoped values are interesting in webbeans, and in some cases
require a generated proxy object, which then requires a protected or
public zero-arg constructor.
If you inject a @RequestScoped bean into an @ApplicationScoped
value, Resin gives you a proxy to the underlying bean. When your
code accesses the request-scoped bean, the proxy will lookup the
actual bean in the current request and invoke the proper methods on
the actual bean.

And then I change the inject method to constructor inject:

public class ListArticleAction extends ActionSupport {
ArticleListBuilder articleListbuilder;
public ListArticleAction(@In ArticleListBuilder articleListbuilder) {

I'm using s080111 snapshot.
I've filed this as http://bugs.caucho.com/view.php?id=2332
Is the object a normal bean or is it something like a struts2
action? If it's a struts action, then it really shouldn't have a
@SessionScope (?), since it's a singleton.
Also, do you have a full stack trace?
thanks,
(BTW, we've added a wiki page for the struts2 integration at http://
wiki.caucho.com/Struts2)
