Transactional Services => BeanNotOfRequiredTypeException, there should be advice, but TransactionInterceptor

After the excellent advice provided in the thread about beans service , I made the Service specified in the section. I tried putting @Transactional at the interface level, interface method level, class level and class. However i do it i get

org.springframework.beans.factory.BeanNotOfRequiredTypeException: Bean named 'org.springframework.transaction.interceptor.TransactionInterceptor#0' must be of type [org.aopalliance.aop.Advice], but was actually of type [org.springframework.transaction.interceptor.TransactionInterceptor]

UPDATE: I get this error only when I defined <tx:annotation-driven transaction-manager="transactionManager/>, but without it, the @Transactional annotation does nothing and I am left without a Hibernate session.

Any idea why I am getting this error? I am new to this, but it looks like I am doing what the PetClinic example does, and I spent hours searching for work on the Internet and browsing through documents, but did not become wiser.

UPDATE: I also found a way to tune myself in to the same error, trying to follow the recommendations of Abhi On Java . I added that all this is at the bottom of this post.

Listed below are my settings, interface, and class. This is the configuration that loads the services (UPDATE: which loads the services at the bottom. The first part deals with my database, etc.):

<!--

This is the interface:

import org.springframework.security.core.userdetails.UserDetailsService;
import org.springframework.transaction.annotation.Transactional;

import tld.mydomain.data.entities.User;
import tld.mydomain.data.entities.keys.UserId;

public interface UserService extends UserDetailsService, CRUDService<User, UserId> {

    @Transactional(readOnly = true)
    public User lookupUser(String username);

    @Transactional(readOnly = true)
    public User publicAliasForUser(String username);
}

and class:

import java.util.List;

import org.hibernate.criterion.Restrictions;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.dao.DataAccessException;
import org.springframework.security.core.userdetails.UserDetails;

import org.springframework.transaction.annotation.Transactional;

import tld.mydomain.commons.RandomString;
import tld.mydomain.data.entities.User;

@Service("userService")
public class UserServiceImpl extends AbstractCRUDServiceImpl<User, String> implements UserService {

    @Autowired
    private LogService logService;

    @SuppressWarnings("unchecked")
    @Override
    public User lookupUser(String username) {

        if(username == null || username.equals("") || username.equals("anonymousUser"))
            return null;

        try {
          List<User> matchingUsers = (List<User>) DAO.getSession().createCriteria(User.class).add(Restrictions.eq("username", username)).list();
          int n = matchingUsers.size();
          if(n == 0) return null;
          if(n > 1) logService.logWarning("Got " + n + " users back, expected just one. Data inconsistency, multiple users with username = " + username);
          return matchingUsers.get(0);
        } catch (Exception ex) {
          logService.logException(ex);
          return null;
        }
    }

    @Override
    public UserDetails loadUserByUsername(String username)
            throws UsernameNotFoundException, DataAccessException {
        if(username == null || username.equals("") || username.equals("anonymousUser"))
            return null;

        User user = this.lookupUser(username);
        if(user == null) {
            logService.logWarning("Couldn't find a user to match, throw out a garbage object");
            user = new User();
            user.setUsername(RandomString.getString(30));
            user.setPassword(RandomString.getString(30));
        }

        return user.getUserDetails();
    }

    @SuppressWarnings("unchecked")
    public User publicAliasForUser(String alias) {
        List<User> publicUsers = DAO.getSession().createCriteria(User.class)
        .add(Restrictions.eq("alias", alias))
        .list();

        if(publicUsers.size() <= 0) return null;
        if(publicUsers.size() > 1) logService.logWarning("Data inconsistency: More than one alias for a user with alias " + alias);
        return publicUsers.get(0);
    }

}

This is the complete exception:

Finally, as promised, here is what I can add to the configuration to get the exact same exception:

 <aop:config>
  <aop:pointcut id="serviceMethods" expression="execution(* tld.mydomain.business..*(..))" />
  <aop:advisor  advice-ref="txAdvice" pointcut-ref="serviceMethods" />
 </aop:config>

 <tx:advice id="txAdvice" transaction-manager="transactionManager" >
  <tx:attributes>
   <tx:method name="*" propagation="REQUIRES_NEW" />
  </tx:attributes>
 </tx:advice>

This again gives me the following exception:

I think now I see the problem:

... [org.aopalliance.aop.Advice], [Org.springframework.transaction.interceptor.TransactionInterceptor]

, TransactionInterceptor org.aopalliance.aop.Advice, , . , Spring, , aop-, . instanceof ClassCastExceptions, .

, app-server, , Spring aop- . , Spring JAR aop-, .
