Getting a 'No thread-bound request found' error from spring in my web app

Question

I'm getting a 'No thread-bound request found' error in my web app and hoping to get some help. I'm trying to use struts2 + spring + hibernate, and use spring to manage the hibernate session factory, and inject hibernate sessions into my struts actions. I hope that made sense. When the app starts up, there are no errors, but when i make the first web request it bombs out with the 'No thread-bound request found' error. Here's my spring config:

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN 2.0//EN" "http://www.springframework.org/dtd/spring-beans-2.0.dtd"> <beans>   <bean id="hibernateSessionFactory" scope="singleton"     class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">     <property name="configLocation" value="classpath:hibernate.cfg.xml" />   </bean>   <bean id="hibernateSession" factory-bean="hibernateSessionFactory"     factory-method="openSession" destroy-method="close" scope="request" class="org.hibernate.Session" /> </beans> 

Here's my action:

package actions.events; import org.hibernate.Session;  public class Listing {   Session session;   public void setHibernateSession(Session value) throws Exception   {     session = value;   }    public String execute() {     return "success";   } } 

My only lead is that if i remove the 'setHibernateSession' function above, i don't get the error because presumably spring doesn't bother creating a session if the action doesn't need one (lazy instantiation).

And here's the exception:

Unable to instantiate Action, actions.events.Listing, defined for 'Listing' in namespace '/events'Error creating bean with name 'hibernateSession': Scope 'request' is not active for the current thread; consider defining a scoped proxy for this bean if you intend to refer to it from a singleton; nested exception is java.lang.IllegalStateException: No thread-bound request found: Are you referring to request attributes outside of an actual web request, or processing a request outside of the originally receiving thread?

Oh and the kicker is that my web.xml does have the necessary context listener, so the http request should be recognised by struts:

<?xml version="1.0" encoding="UTF-8"?> <web-app ...   ...   <listener>     <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>   ... </web-app> 

Answer 1

To use request scope without Spring MVC, you should declare RequestContextListener in web.xml (see 3.5.4.1. Initial web configuration):

<web-app>   ...   <listener>     <listener-class>         org.springframework.web.context.request.RequestContextListener     </listener-class>   </listener>   ... </web-app> 

Answer 2

If you are configuring your app using Java instead of XML the same conf can be applied in

 public void onStartup(ServletContext servletContext) throws ServletException {           //add listener           servletContext.addListener(new RequestContextListener());
