A good place to look is the recipient EIP pattern wiki:
http://activemq.apache.org/camel/recipient-list.html
It was recently updated documenting how it computes the list of receivers.
It should be something that can be iterated, such as a List<String> or
the likes.
If whatever iBatis returns isn't that you can use a processor to
convert it in Java code

<processRef ref="mySpringBeanThatIsAProcessor"/>

And then you can have a class that implements
org.apache.camel.Processor where you can set the List<String> as the
IN body yourself.
