[news.eclipse.rt.eclipselink] Unknown entity type - addl details

[Serge <sergeyext@xxxxxxxxx>]

 - javax.persisten.jar is for jpa 2.0

 - if I replace eclipselink with either toplink or hibernate(not sure 
with version) all works. i.e. add toplink/hibernate libraries and 
replace provider/properties in persistence.xml.
