Re: Problem using @SpringBean with Wicket 1.3.5
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:

Kent, I am using 1.3.5 fine with springbean. some differences that I see
between your/mine is that I have the protected modifier.
Mine:
@SpringBean(name = eventService) protected EventService
eventService;
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 .
another difference: Try adding a slash to the beginning of your spring path
param-valueclasspath:/applicationContext.xml/param-value
They don't use any slash in the example in Wicket in Action. But maybe they
both work. At least not using one works.
Do you have a bean by the name of userRegistrationService in your spring
context? In your code, you are just requesting a bean of the type, not by
id.
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.)
try doing a ctx.getBean(userRegistrationService) and make sure it's not
null.
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!

I have an application with Spring beans which I want to use from Wicket,

public UserRegistrationService getUserRegistrationService() {

In my class which extends WebApplication (my Application class). It works
fine that way! So it must have something to do with how I try to use the

public UserRegistrationPage(final PageParameters parameters) {

}
But when I try this I get
WicketMessage: Can't instantiate page using constructor public

and argument
I have a complete stack trace at pastebin (to not pollute the mail with
it)

I hope someone more experienced with Wicket than me knows what's going on
here. I've tried to solve it for a couple of hours, but I can't find any

Thanks Igor!
That helped me.
I wrote this in our internal documentation and I'm including it in case
someone searches for this problem:

Re: Problem using @SpringBean with Wicket 1.3.5
Kent,
I am using 1.3.5 fine with springbean.
some differences that I see between your/mine is that I have the
protected modifier.
Mine:
@SpringBean(name = eventService)
protected EventService eventService;
another difference:
Try adding a slash to the beginning of your spring path
param-valueclasspath:/applicationContext.xml/param-value
Do you have a bean by the name of userRegistrationService in your
spring context?
In your code, you are just requesting a bean of the type, not by id.
try doing a ctx.getBean(userRegistrationService) and make sure it's
not null.
