Exception when deploying XSD ruleset to Java AS

I'm getting the following exception when deploying a XSD ruleset to the Netweaver Java AS:

com.sap.engine.interfaces.sca.assembly.AssemblyException: Component {http://www.sap.com} ... does not have a valid implementation type. Verify component implementation type is correct in .composite file and corresponding implementation provider is up and running.

Are there any specific components that need to be running on the Java AS so I can deploy rulesets to it?
