Hi,

I created a sample project for testing spring session bean with aop proxy. When I added a method to handle method Post in the controller, during deployment, jboss 7.1.1 thrown the following exception:

jboss.web.deployment.default-host./: Failed to start service

Controller code:

package testsession.domain;

import org.springframework.stereotype.Controller;

import org.apache.log4j.Logger;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.ui.Model;

import org.springframework.validation.BindingResult;

import org.springframework.web.bind.annotation.ModelAttribute;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.support.SessionStatus;

import testsession.domain.bean.CategorySessionBean;

@Controller

public class TestController {

    private static final Logger logger = Logger.getLogger(TestController.class);

    @Autowired

    private CategorySessionBean categorySessionBean;

    @RequestMapping(value = "/", method = RequestMethod.GET)

    public String home(Model model) {

        logger.debug(" =======HOME PAGE========");

        model.addAttribute("categorySessionBean", categorySessionBean);

        return "index";

    }

    @RequestMapping(value = "/popupPage", method = RequestMethod.GET)

    public String popupPage(Model model) {

        logger.debug(" =======POPUP PAGE========");

        model.addAttribute("categorySessionBean", categorySessionBean);

        return "popupPage";

    }

    @RequestMapping(method = RequestMethod.POST)

    public String processSubmit(

        @ModelAttribute("categorySessionBean") CategorySessionBean categorySessionBean, BindingResult result, SessionStatus status) {

        return "index";

    }

}

Any suggestion is very appreciated.

Thanks
