Re: DI in wicket
Hi,
I have done the configuration in web.xml.
When I print the DAO reference, it is printing like
org.apache.wicket.proxy.LazyInitProxyFactory$JdkHandler@f2164f
But the error has been thrown like
"org.apache.wicket.WicketRuntimeException: Can't instantiate page using
constructor 'public com.wicket.pages.IndexPage()'. Might be it doesn't
exist, may be it is not visible (public)."
Kindly find the Page class, which throws the exception
public class IndexPage extends WebPage
{
@SpringBean(name="userDao")
private UserDao userDao;
public IndexPage()
{
System.out.println(userDao);
add(new Label("sampleLabel", "This is a text which is also a model."));
userDao.test();
}
}

Hi,
Just like to use DAO pattern with Spring in wicket. If any other link for
references would be of great help.

Re: DI in wicket
Posted by James Carman <ja...@carmanconsulting.com>.
This is a Spring issue, not a Wicket issue. You're not configuring
Spring correctly. If you want a working example that uses
Spring/Hibernate, you can try Wicketopia's example application. It
has everything configured correctly out of the box.
http://wicketopia.svn.sourceforge.net/svnroot/wicketopia/trunk/example
(wicket 1.4 version)
https://wicketopia.svn.sourceforge.net/svnroot/wicketopia/branches/wicketopia15main/example/
(wicket 1.5 version)
Hope that helps.
