[Teneo] many to many relations with java-annotations [message #114387] Mon, 10 March 2008 11:28 Go to next message

Hi Martin,

i want to create a n:m relation table by using annotations in some given
java- interfaces.
So i guess i have to use the @ManyToMany tag from the javax.persistence lib?
Unfortunaly i'm using Java SE and the javax.persistence package doesn't
seem to be part of it.
Is there another way to create n:m tables with java-annotations? Or did
i just overlooked the lib anywhere else?

Thanks for your advice,
Mario

Hi Mario,
With Teneo the annotations are specified on model level, either in the model itself or in a separate
xml file. See here:
http://www.elver.org/hibernate/ejb3_format.html
Here is an example of specifying many-to-many in a xml schema:
http://www.elver.org/hibernate/ejb3_examples.html#mtm
this can also be done in xml on in ecore.

For jpox the same applies

As Teneo uses annotations on model level it is not required to have the javax.persistence jar. Teneo
works for both hibernate (session and entitymanager api) and jpox (persistencemanager api).
