Hey,
EclipseLink newbie here. After getting the provided library sample to
run, I set out to make my own smaller example to get to grips with how
the whole thing worked.
I'm sorry if I'm a little verbose about it, but I want to be 100% sure I
didn't screw up somewhere along the way.
I created an Ecore model with an Author class (with a name EString
tagged as ID) and a Book class (ID is a title EString) with a one-to-one
reference to Author; I then used this .ecore file to create a genmodel
and generated all.
Then, I generated the orm.xml file using the menu and set up my
persistence.xml to use derby's embedded driver.
I'm running into two issues here:
1)Generating the orm file invariably raises a popup stating that:
An internal error occurred during: "Generate Mapping File".
java.lang.NullPointerException
This popup leads to the error log, where I find the following:
eclipse.buildId=M20100211-1343
java.version=1.6.0_02
java.vendor=Sun Microsystems Inc.
....
java.lang.NullPointerException
at org.eclipse.core.runtime.CoreException.<init>(CoreException.java:44)
at
org.eclipse.emf.teneo.eclipse.genxml.RunGenerateJob.runInWor kspace(RunGenerateJob.java:111)
at
org.eclipse.core.internal.resources.InternalWorkspaceJob.run (InternalWorkspaceJob.java:38)
at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
Despite this, an orm file is generated which (to my untrained eyes)
doesn't seem suspicious or malformed.
2)Attempting to run my test class with it leads to the following
exception, however:
Exception in thread "main" Local Exception Stack:
Exception [EclipseLink-30005] (Eclipse Persistence Services -
2.0.2.v20100323-r6872):

properties annotated) in your entity class hierarchy.

Hi Philippe,
Can you enter a bugzilla on Teneo for the NPE, with the full stacktrace?
For the other issue (no id member) you can solve this by defining one of the efeatures of the eclass as the id. You do
this by setting an eannotation on the efeature. The efeature should have the source: 'teneo.jpa' a key called 'value'
and a value: @Id.
See here for the annotation format:
