Spring xml, array of arrays, or list of lists

Question

How does one define an array of arrays in Spring xml? Or a list of lists? Tried many things (util:list, value-type="java.util.ArrayList", etc, etc etc, none worked. Essentially:

<bean id="id">
   <array>
      <array>
         <value>aa</value>
         <value>ab</value>
         <value>ac</value>
      </array>
      <array>
         <value>ba</value>
         <value>bb</value>
         <value>bc</value>
      </array>
   </array>
</bean>

Or:

<bean id="id">
   <list>
      <list>
         <value>aa</value>
         <value>ab</value>
         <value>ac</value>
      </list>
      <list>
         <value>ba</value>
         <value>bb</value>
         <value>bc</value>
      </list>
   </list>
</bean>

Finally found something that worked. Instead of trying to call the elements values, call them beans. I little less than intuitive declaring a bean nested inside another bean, but it is allowed and works.

    <bean id="wxSetup" class="java.util.ArrayList">
        <constructor-arg>
            <list>
                <bean class="java.util.ArrayList">
                    <constructor-arg>
                        <list>
                            <value>aa</value>
                            <value>ab</value>
                            <value>ac</value>
                        </list>
                    </constructor-arg>
                </bean>
                <bean class="java.util.ArrayList">
                    <constructor-arg>
                        <list>
                            <value>ba</value>
                            <value>bb</value>
                            <value>bc</value>
                        </list>
                    </constructor-arg>
                </bean>
            </list>
        </constructor-arg>
    </bean>
