Subject Re: @Transactional Spring Annotation in a Struts2 Action does not work
Date Fri, 01 May 2009 02:41:39 GMT
Hi Jeroen,

The problem is that I am not a big fan of services layer. Sometimes it looks
very anemic to me. But I totally agree with you when you say the action
should not know about persistence problems, and that's why I want to do it
via AOP.

I had the same thought about the problem: the Spring proxy does not work
properly with all the magic Struts2 and Reflection do!

I tried to open a bug in the Struts2 JIRA, but they closed it and said that
it works. I think it should be some kind of spring or struts configuration I
am not doing right.

Thanks in advance,
Mauricio
