Hi Phillip,
The help I got from Igor Vaynberg solved my problem. It was the security
manager which was restricting my application from using the Reflection API.
I wrote this in our internal documentation:
A change which is normally done in the conf file catalina.policy is needed.
Ubuntu prefers to split that file into different parts and merge it before
starting the service. If we would edit catalina.policy our changes would be
lost next time the server starts and would never come in effect as that's
when the file is read. Instead we edit
"/etc/tomcat5.5/policy.d/04webapps.policy" and add the following three lines
to it at the end (webcarrot is the web project directory name):
grant codeBase "file:/var/lib/tomcat5.5/webapps/webcarrot/-" {
permission java.lang.reflect.ReflectPermission "suppressAccessChecks";
};
I comment your answer below:

It works using private too.
As far as the Reflection API is concerned It does not matter. You can read
and change private fields using Reflection as well. It could matter if the
wicket-spring-annot project had made some decision to only support protected
& public modified fields. But I think it's a long shot and the Wicket Wiki
example uses private too: http://cwiki.apache.org/WICKET/spring.html .

They don't use any slash in the example in Wicket in Action. But maybe they
both work. At least not using one works.

No I named it UserRegistrationService (with a capital U). Yes I am
requesting by type, so why would the name matter? (I don't think it does.)

I can get the bean by name using @SpringBean too. I tried changing my bean
definition (so there would be no name-class relation) to:
<bean id="getmebymyname"
class="net.opentranslation.webcollab.service.UserRegistrationServiceImpl" />
And then I used it using
@SpringBean(name="getmebymyname")
UserRegistrationService userRegistrationService;
And it worked well.
Thank you for trying to help me though!
