I am trying to use a session scoped bean in my application. I am doing the same what you showed in your example, but getting following error: ---------------------------- Caused by: org.springframework.beans.PropertyBatchUpdateException; nested PropertyAccessException details (1) are: PropertyAccessException 1: org.springframework.beans.TypeMismatchException: Failed to convert property value of type [$Proxy53] to required type [com.bglobal.reuse.hibernateApp.value.UserInfo] for property 'userInfo'; nested exception is java.lang.IllegalArgumentException: No matching editors or conversion strategy found Caused by: java.lang.IllegalArgumentException: No matching editors or conversion strategy found --------------------- Appreciating your time and effort in advance, Umang Hi, thank you for your example.

I suspect you've got something else in your context. It looks like you're injecting something (maybe the session scoped bean?) that isn't of the same type as the property in the bean into which you are injecting it. Ron - thanks ;-)

I was looking for a way to do that and spring provides this nice mechanism through AOP. Thanks for enlightening us on this feature. Nice article.

I had everything right except the RequestContextListener setup in the DD, once this article cleared up that issue for me. Thanks, this article saved my ass at work.

The one gotcha (after a day of pain) to watch out for is to add spring-aop dependency jar in the pom (classpath). Spring ignores the tag is ignored and the bean is treated like a singleton when the aop jar did not exist in the classpath. Thanks for the article.

Now, A - I love the CSS style for the site. B - How do I gain access to the session using the DispatchServlet ? I am using a MultiActionController and for some reason some session attributes I cannot access. Originally, I added a regular servlet and extracted the attributes I needed, the forwarded it to the Spring application. Although this is a hack, I'm sure there are better ways to do this. Any advice? Warm regards, Josh Boston, MA. First and foremost, great site and great content.

Basically I don't want to instantiate that bean for all users session, but just users with admin priviledges. Is it possible to control this with IOC settings in Spring?

For example, call your method: public ModelAndView viewCart(HttpServletRequest req, HttpServletResponse res, HttpSession ses) { ..} Grep for "anyMeaningfulName" in <a href="http://static.springframework.org/spring/docs/2.5.x/reference/mvc.html#mvc-servlet" rel="nofollow">this doc</a>.

Setup my spring mvc and deployed into to the springsource application platform (s2ap) executing the following line always throws a NullPointerException ac = WebApplicationContextUtils.getRequiredWebApplicationContext(request.getSession().getServletContext()); In my partly web.xml I added the one approriate listener: org.springframework.web.context.request.RequestContextListener Does anyone have a clue or a hint on this issue ??? thanks for your documentation.
