Hi

I m able to get values using JPA when i have only mapped one table

Now when i have gone for mapping related tables i get the error



I m using [EclipseLink-0] (Eclipse Persistence Services - 2.0.1.v20100213-r6600)

In one of the child tables i have this code



What changes i have to do in this code to make the fields read-only

or are there any better workaround for not making these fields read only

Thanks

You are using the same foreign key field in both ManyToOne's, this makes no sense. You must use different foreign key fields for each relationship.
