Same result. I'm running in Geronimo 2.1.3 which IIRC comes with OpenJPA 1.0.2. As such, I couldn't use the syntax you suggested, so I used the one that compiles. The javax.persistence library with 1.0.2 says "mappedBy" wasn't found... so I used this syntax in UserProperties:
@ManyToOne(targetEntity=UserInfo.class, fetch=FetchType.LAZY) @JoinColumn(name="user_id", referencedColumnName="id") private UserInfo userInfo; Basically, the only change was changing "mappedBy" to "targetEntity". And, I've tried this same change to both UserProperties and UserInfo with the same results I was getting originally. Thanks, Randy ---- [EMAIL PROTECTED] wrote: > Thanks for the quick reply.
