You could use <bean:size> to get the size of the list and conditionally execute the logic:iterate, something like this :
<bean:size id="id" name="collection" />
<logic:lessEqual value="0" name="id">
The length is zero
</logic:lessEqual>
<logic:greaterThan value="0" name="id">
//your logic:iterate here...
</logic:greaterThan>

That will work, but not necessary. If the collection is empty, the iterate tag just skips - it doesnt throw an exception (tested)
The problem I guess is that the bean with the specified name is not a Collection. It may be a property of the bean that is a collection in which case the tag should have a property attribute.
ram.
