Help with Logical Locking

I'm trying to use Logical locking in an application, but I keep getting this error at runtime:

java.lang.NoClassDefFoundError: com/sap/engine/services/applocking/LogicalLockingFactory

I'm sure I'm missing an application reference in application-j2ee-engine.xml, but I don't know what to add.

Here's what I have right now:

	<reference 
		reference-type="hard">
		<reference-target 
			provider-name="sap.com" 
			target-type="application">applocking</reference-target>
	</reference>

Any help would be great. Thanks in advance.
