EclipseLink workbench and ManyToOne [message #385996]

Today I try to rebuild the model classes from the rcp example
(org.eclipse.persistence.example.jpa.comics.model.annotated) as
unnotaded POJO's and create the mapping by an xml-file.
For this I try to use the EclipseWorkbench, but to rebuild the mapping
of the Publisher in the Title class, I dont found a Button for the
mapping ManyToOne.

-->@ManyToOne(fetch=FetchType.LAZY)

Is ist possible that this only works with JPA 2.0 and the workbench
works only with JPA 1.0 or this error by me again. ;)

Thanks in advance,
Heiko

Heiko,

The Workbench supports our native ORM mappings that pre-date JPA 1.0. The
output is our native XML mapping file can be used with JPA but is not part
of the standard. Generally the Workbench is not used by new projects
adopting JPA it is intended for existing users who have already been using
the Workbench from earlier TopLink releases.

If you wish to use XML configuration files with JPA I would recommend
using JPA's orm.xml mapping files. Using Dali you can create these files
and configure the mappings in a similar fashion to how you would configure
the annotations. We have published some examples of this:

BTW: In our native ORM we use the 1:1 mapping with different configuration
options for both the 1:1 and M:1 scenarios defined by JPA.
