<tx:annotation-driven /> Inconsistent stack height 2 != 1

[ankit909]

Hi,

I am using <tx:annotation-driven /> as shown :

    <?xml version="1.0" encoding="UTF-8"?>  
    <beans xmlns="http://www.springframework.org/schema/beans"  
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

     xmlns:context="http://www.springframework.org/schema/context"  
     xmlns:tx="http://www.springframework.org/schema/tx"  
     xsi:schemaLocation="http://www.springframework.org/schema/task

            http://www.springframework.org/schema/context/spring-context-3.0.xsd">  
          
            <tx:annotation-driven/>

and the error it is giving is :

Caused by: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'chatSessionDAO' defined in file [/local/jboss-eap-4.2/jboss-as/server/mercer02/deploy/mercerhr.ear/mercer.war/WEB-INF/classes/com/mercer/chat/app/dao/ChatSessionDAO.class]: Initialization of bean failed; nested exception is java.lang.VerifyError: (class: com/mercer/chat/app/dao/ChatSessionDAO$$EnhancerByCGLIB$$c2bd3f90$$FastClassByCGLIB$$bc114739, method: invoke signature: (ILjava/lang/Object;[Ljava/lang/Object;)Ljava/lang/Object;) Inconsistent stack height 2 != 1

here is my ChatSessionDAO class :

Repository("chatSessionDAO")  
@Transactional  
public class ChatSessionDAO extends MercerChatDAO {  
  
    /** mySessionFactory */  
    @Autowired  
    @Qualifier("mySessionFactory")  
    private LocalSessionFactoryBean mySessionFactory;  
  
    /** chatAlertsDO */  
    @Autowired  
    @Qualifier("chatAlertsDO")  
    private MHRContChatAlertsDO chatAlertsDO;  
  
    /** 
     * Method to retrieve chat session objects for a particular id 
     *  
     * @param chatSessionQO 
     * @return 
     * @throws MercerException  
     */  
    public List<?> retrieveSessionInfo(ChatSessionQO chatSessionQO) throws MercerException {  
        Criteria criteria = null;  
        List<?> lstReturn = null;  
        try {  
  
            long chatSessionId = chatSessionQO.getChatSessionId();  
            Long chatSessionIdLong = new Long(chatSessionId);  
            log.info("creating criteria for chatsession");  
            SessionFactory sessionFactory = mySessionFactory.getObject();  
            Session session = sessionFactory.getCurrentSession();  
            criteria = session.createCriteria(MHRContChatSessionDO.class, "chatSession").add(  
                    Restrictions.eq("id", chatSessionIdLong));  
            if (criteria != null) {  
                lstReturn = processQuery(criteria);  
            }  
  
        } catch (Exception e) {  
            log.error("error :::", e);  
            throw new MercerException("No transaction");  
        }  
        return lstReturn;  
    }  
..... other methods

I am new to Spring transaction so dont have much idea about that. I am using JTA transaction Manager
