Ok the Entity class relationship defined on the Department.getUsers is @javax.persistence.OneToMany and thats on the getter and not the attribute. So, JSP could not be calling the attribute directly as the LazyInitializationException is thrown and @OneToMany that would cause it is defined on the getter. My jboss-aop.xml if defined in a separate jar file in the root of the .ear. | MyEAR.ear/ | | | |-----MyEJBClient.jar/ | | | | | |----- META-INF/jboss-aop.xml | | | | | |----- com.mycomp.aop.myinterceptors.* | | |----- com.mycomp.entity.* | | | |-----MyWebApp.war/ | | | |---- the Servlets + JSP | View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4231584#...
