When trying to open/preview a (very simple) POJO dataset which uses EclipseLink/JPA I get the following exception:
org.eclipse.birt.data.engine.odaconsumer.OdaDataException: Cannot execute the statement.

Has anybody a working example of a POJO-Dataset using EclipseLink or any idea how to fix this problem?
Thanks in advance
Thomas
