Spring @Transactional not working

I previously had a post on this issue that was resolved. However since rebuilding the project with auto wired beans and less XML configuration I find I am revisiting this issue. I have followed the way my previous project implemented this but it doesn't work. Can someone help me with why or what I should change to make it work?

I am on purpose using a non existent table name in the insert user details method to deliberately throw an exception. However the statements for insert user and insert user roles are not rolled back. Please help.

My current design for the registration is like this.

Part of servlet.xml:

<context:component-scan base-package="com.doyleisgod.golfer.controllers"/>
<context:component-scan base-package="com.doyleisgod.golfer.dao"/>
<context:component-scan base-package="com.doyleisgod.golfer.services"/>
<context:component-scan base-package="com.doyleisgod.golfer.validators"/>

Part of application context:

<context:annotation-config />
<tx:annotation-driven />    

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
</bean>

<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

Registration controller:

package com.doyleisgod.golfer.controllers;

import javax.validation.Valid;

import org.apache.commons.logging.Log;
import org.apache.common
