How to call multiple http webservice on mule thread in transaction?

I'm new to the mule. I have a wm6-hyernate mule setup. Suppose there are 3 webservice.Aim to call all these web services on a mule thread so that all 3 are in a transaction. so suppose if the 3rd webservice fails, the previous 2 will be automatically dropped.

Here is my code snippet that I tried. my mule-flow.xml ( currently I have only one webservice,kindly let me know how can I add multipe webservice call in flow?

)

<spring:beans>
 <spring:import resource="classpath:spring-mule.xml"/>
 <spring:import resource="classpath:applicationContext-persistence.xml"/>
</spring:beans>

<flow name="addCustomer" doc:name="addCustomer">
<http:inbound-endpoint exchange-pattern="request-response"
address="http://localhost:8081/pos/addCustomer" doc:name="HTTP" />

<cxf:simple-service serviceClass="com.proj.pos.webservice.interfac.CustomerService" doc:name="SOAP"/>
<component ><spring-object bean="customerService"/></component>
</flow>

</mule>

      

        
        
        
      

    

My spring-mule.xml

<bean id="customerService"  class="com.proj.pos.webservice.implementation.CustomerServiceImpl">
    <property name="cusDao" >
    <ref local="customerDao"/>
    </property>
    </bean>

      

        
        
        
      

    

Mine: ApplicationContext-persistence.xml

     <bean id="datasource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="driverClassName" value="oracle.jdbc.OracleDriver" />
<property name="url" value="jdbc:oracle:thin:@localhost:1521:xe" />
<property name="username" value="xyz" />
<property name="password" value="xyz" />
</bean> 

    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate3.LocalSessionFactoryBean">
        <property name="dataSource" ref="datasource" />
        <property name="configLocation">
            <value>classpath:hibernate.cfg.xml</value>
        </property>
        <property name="configurationClass">
            <value>org.hibernate.cfg.AnnotationConfiguration</value>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.Oracle10gDialect</prop>
                <prop key="hibernate.show_sql">true</prop>
                <prop key="cache.provider_class">org.hibernate.cache.NoCacheProvider</prop>
                <prop key="hibernate.connection.release_mode">auto</prop>
            </props>
        </property>
    </bean>

    <tx:annotation-driven />
    <bean id="transactionManager"
        class="org.springframework.orm.hibernate3.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

     <bean id="customerDao" class="com.proj.pos.dao.implementation.CustomerDaoImpl">
    <property name="sessionFactory">
    <ref local="sessionFactory"/>
    </property>
    </bean>

      

        
        
        
      

    

my CustomerServiceImpl

@WebService(endpointInterface = "com.proj.pos.webservice.interfac.CustomerService",
        serviceName = "CustomerService")
public class CustomerServiceImpl implements CustomerService {

    @Autowired
    private CustomerDao cusDao;

    @Transactional  //NOTE:USING THIS ANNOTATION I AM ABLE TO ACHIEVE THE BELOW METHOD //IN TRANSACTION,BUT I BELEIVE THIS FEATURE WILL NOT WORK IF WE HAVE MULTIPLE WEBSERVICE CALL
    @Override
    public Customer addCustomer(CustomerDto dto) {
        Customer customer=new Customer(dto.getCustomerId(), dto.getFname(), dto.getLname(), dto.getAge(), dto.getDateOfBirth(), dto.getAddress());
        customer.setCustomerId(cusDao.persist(customer));
         return customer;
    }

    public CustomerDao getCusDao() {
        return cusDao;
    }

    public void setCusDao(CustomerDao cusDao) {
        this.cusDao = cusDao;
    }

}

      

        
        
        
      

    

Please let me know any solution. thank
