I am trying to work out how to do the mappings for two different projects that share some entities. Since they share only a limited subset of mappings, my first idea was to separate these mappings out into a separate jar. I'm using hibernate annotations to do the mappings (so they're in the class files, not separate XML). Both project A...

The table I'm trying to map looks like: TABLE example { ID INT, CATEGORY VARCHAR, PROPERTY VARCHAR, VALUE VARCHAR); A single id can have several rows (obviously, not a primary key). As an example, it could look like: # ID ...
Why does the UniqueConstraint annotation in the following Hibernate mapping declaration cause the exception java.lang.NoSuchMethodError: javax.persistence.UniqueConstraint.name() (see below for stack trace)? Note that when I remove the UniqueConstraint annotation, Hibernate does not throw the exception and Spring successfully creates th...
When implementing composite primary keys in Hibernate or other ORMs there are up to three places where to put the insertable = false, updatable = false in composite primary key constellations that use identifying relationships (FKs that are part of the PK): Into the composite PK class' @Column annotation (@Embeddable classes only) or I...

When using the @Any annotation in hibernate how can you create the reverse mapping field, for use with orphan removal. My code looks like the example below, except that classes A and B each have their own inheritance hierarchies which is why I can not make Interface I an abstract class. public Interface I; @Entity public Class A impl...
