NoClassDefFoundError during ES4 deployment

I am installing ES4 on WebLogic/Linux. Everything goes smooth until about 75% of the way through component deployment I get this:

[ALC-LCM-030-200]: Failed to deploy component /opt/adobe/adobe_livecycle_es4/deploy/adobe-processdata-storageprovider-dsc.jar

. . .

Caused by: ALC-DSC-099-000: com.adobe.idp.dsc.DSCRuntimeException: javax.ejb.EJBException: EJB Exception: : java.lang.NoClassDefFoundError: javax/jcr/RepositoryException

Has anyone seen this before?

Thanks in advance!
