Have you forgto to declare the wrapping TimerFactoryBean? The
documentation is a little tricky regarding this, as it seems to be
complete with the TimerTask section adding the necessary Factory in
the next but one section.
So you should have someting like this:
<bean id="timerFactory"
class="org.springframework.scheduling.timer.TimerFactoryBean">
<property name="scheduledTimerTasks">
<list>
<ref bean="scheduledTask" />
</list>
</property>
</bean>
