Vaadin7 + Spring4 + Hibernate4
Hi,
I have a Vaadin 7 project. It's works. Now I need to implement Hibernate 4 to access Database and I want to use also Spring 4 to use its annotations.
The problem is that the autowired annotation doesn't work. The related object is always null.

I don't understand the reason.

Hi,
Looks quite complex when compared to the this instructions. But anyway, it looks like your UI is not a bean managed by Spring, so it's natural that Spring won't inject any dependencies. Don't know if in your case adding only the @Component annotation (or corresponding XML) will help as I didn't really read all the code you published, but hope it helps.
