Hey Sergey,
As far as I know it should create only a single instance for each
spring bean (if they are singletons that is). Thus always the same
bean should be injected into your wicket classes. Does this problem
occur with the @SpringBean or using the proxy approach? I've been
using @SpringBean

Well, in order for the reference to be set, the object used must
adhere to the same API. The object is, indeed a proxy. So, the proxy
either implements the same interface as the type of the field or
extends the class of the type of the field (you should be using
interfaces if at all possible).
Okay, this question might actually be more related to Spring, but I'm
completely lost here, and my question on Spring forums usually don't get any
replies, so I hope Wicket community might help as it usually does.
I'm using JCR, and have a RepositoryDao bean configured in
applicationContext.xml.
Hello,
I am not entirely sure if I understand your question correctly. But I
usually use Spring like this:
YourDao (either defined in applicationContext.xml or in separate
spring-config files, or annotation-driven e.g. with @Repository. The
template you mention I usually autowire into the dao so
As far as I am aware, the main internal differential is that annotations
provides a quick, safe way to access your spring beans and ensure that the
whole container does not get serialized via a proxy. However the magic comes
at a cost that it will serial the bean id (as a string) - which can be
Okay, thanks for you replies, my question was poorly formulated. There are
two issues here.
First problem is that I apparently don't understand some very basic
principles behind Spring-configured beans handling.
I assume that a DAO configured in Spring are created on application
deployment,
To answer your question, yes spring beans are singleton by default. The
@SpringBean annotation works roughly like this: in your Application class,
you set a ComponentInstantiationListener which gets called every time a
Wicket page/component is instantiated. The particular listener that gets set
Thanks for your insight, Patrick.

Also, it's not the injected beans that are null, it's their dependencies,
