I have a one-to-many as shown below and receive Error parsing XML (337) : The content of element type "one-to-many" must match "EMPTY". This started to happen after I updated the Doctype to

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

We recently upgraded to version 3 of hibernate. In addition, the failure only occurs on an updated version of iplanet 7. Any ideas on what I need to do to get this error corrected short of eliminating iplanet 7 and revert to the previous version.
