Using session scoped Spring bean with DWR
dwr, spring
Solution
In order for session- or request-scoped beans to work in Spring, something has to associate the current request and session with the current thread. Normally, this would be done by `DispatcherServlet`, but if you're not using that, then you need an alternative.
The alternative in this case is `RequestContextListener` or `RequestContextFilter`, either of which you can wire in to your `web.xml`, and both os which will allow you to use request- and session-scoped beans. Just make sure that you configure them in `web.xml` so that DWR requests pass through them.
Problem
Spring: 2.5.6.SEC01 DWR: 2.0.5 I would like to use a session scoped bean from DWR. It works fine, when I configure the bean to be a singleton. I read this tutor: (http://directwebremoting.org/dwr/server/integration/spring.html) and modified my applicationContext.xml, but it is still wrong somewhere. My applicationContext.xml: http://pastebin.com/m8d57f18 It ork well, but when I use an AJAX function, I get this exception: 11:31:09,593 INFO [DefaultRemoter] Exec: DBTestAjaxFunc.testJNDI() 11:31:09,609 WARN [DefaultRemoter] Method execution failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scopedTarget.dbtestajax': Scope 'session' 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? If you are actually operating within a web request and still receive this message, your code is probably running outside of DispatcherServlet/DispatcherPortlet: In this case, use RequestContextListener or RequestContextFilter to expose the current request. It seems, that the aop proxy wasn't created, but I don't know why. Libs in the classpath: - aspectjrt.jar - aspectjweaver.jar - cglib-nodep-2.2.jar - dwr.jar - spring.jar - spring-aop.jar - spring-dwr-2.0.xsd - spring-web.jar - spring-webmvc.jar Any idea? (Thanks!)
