I'm trying to instantiate my ActionBeans through guice so that I can
put @Transactional annotations on my event handler methods. So far it
seems to be my holy grail for transaction management in a web
environment, but it is proving difficult to attain. Has anyone
successfully done this?
I've identified two problems so far beyond those already identified by
others on the mailing list (which were apparently solved by using an
ActionResolver similar to the one I have included below).
1.) @Before/@After annotations are ignored, presumably because the
BeforeAfterMethodInterceptor is not examining annotations on the
proxied ActionBean's superclass(es).
2.) Numeric indexed properties (item[0], item[1], etc) are not being
set on form submission.
Other annotations may not be working either. I have tested
@UrlBinding and @ValidationMethod, so I can confirm that they appear
to be working.
Thanks,
Michael Day
