Transaction Aspect not applied for Custom Spring Controller

[Nettar]

Hi,

I am using Google Web Toolkit -> Spring -> Hibernate combination.

I have implemented spring's Controller as below:


public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) throws Exception
{
service(request, response);
return null;
}

and here is my spring config xml:


<bean id="dataSource"
class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="url" value="jdbc:mysql://localhost/TESTDB" />
<property name="username" value="root" />
<property name="password" value="pass" />
</bean>

<!-- Hibernate SessionFactory Configuration -->

<bean id="sessionFactory"
class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.generate_statistics">true</prop>
</props>
</property>
<property name="mappingResources">
<list>
<value>Login.hbm.xml</value>
<!-- Add more Mapping Resources here -->
</list>
</property>
</bean>

<!-- Transaction Management -->

<bean id="transactionManager"
class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>

<tx:advice id="transactionAdvice"
transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="*" propagation="REQUIRED"
rollback-for="java.lang.Exception" />
</tx:attributes>
</tx:advice>

<aop:config>
<aopointcut id="allServiceOperations"
expression="execution(* com.mycompany.service.*Service.*(..))" />
<aop:advisor pointcut-ref="allServiceOperations"
advice-ref="transactionAdvice" />
</aop:config>

This is my service class:


package com.mycompany.service;

import com.mycompany.spring.GWTSpringController;
import com.mycompany.service.LoginService;
import com.mycompany.databeans.Login;
import com.mycompany.controller.LoginController;

public class LoginServiceImpl extends GWTSpringController implements
LoginService
{
private LoginController loginController;

public void setLoginController(LoginController loginController)
{
this.loginController = loginController;
}

public boolean login(Login login)
{
return loginController.login(login);
}
}


Now, when I make a request, I get an exception which says:


org.hibernate.HibernateException: No Hibernate Session bound to thread,
and configuration does not allow creation of non-transactional one here



However, I change the pointcut expression to

execution(* com.mycompany.controller.*Controller.*(..))

it works fine.

Why am I facing this problem?

Is something wrong going on when the Google Web Toolkit invokes login()
on my service implementation because of which Spring cannot apply
transaction aspect?

Kindly help me.
