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.
