Re: [struts-user] Re: struts2 json return null if involve hibernate or spring
What is the status of the Hibernate/JPA session at the time of the View
rendering?
i just use the following session approach in the application.xml
in the CartManagerImpl.java public class CartManagerImpl implements
CartManager {
CartDao cartDao; public void setCartDao(CartDao cartDao) {
this.cartDao=cartDao; } public void removeSingle(Cartitem item)
throws Exception { cartDao.deleteSingle(item); }

In my expereince yes, regarding lazy loading and caching. But your code sample
does not give enough detail to say if that is likely. What is the status of the
Hibernate/JPA session at the time of the View rendering?

Re: struts2 json return null if involve hibernate or spring
the delete itself has no problem if called it directly.

struts2 json return null if involve hibernate or spring
is hibernate dao manipulation could affect struts 2 json return? or spring framework could affect struts2 json return? my program's struts2 json execution is success if not involve dao or spring call. but if involve hibernate/spring/dao manipulation, then json return is null and not returned. struts.xml ... Cart.jsp <%@ taglib prefix="s" uri="/struts-tags" %> <%@ taglib prefix="sj" uri="/struts-jquery-tags"%>
