[Building Sakai] Spring help

[Charles Severance]

I am in the Basic LTI service servlet and trying to get my hands on the LessonBulder simpleDAO api using this code:

import org.sakaiproject.lessonbuildertool.model.SimplePageToolDao;

if ( simplePageToolDao == null ) simplePageToolDao = (SimplePageToolDao)ComponentManager.get(SimplePageToolDao.class);

I get this error:

2012-06-22 10:49:30,846  WARN http-bio-8080-exec-4 org.sakaiproject.component.impl.SpringCompMgr - get(org.sakaiproject.lessonbuildertool.model.SimplePageToolDao): 
org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'org.sakaiproject.lessonbuildertool.model.SimplePageToolDao' must be of type [org.sakaiproject.lessonbuildertool.model.SimplePageToolDao], but was actually of type [$Proxy61]

Any thoughts/suggestions to get this to work?
