Installed from the .jar installer, using the EJB3 configuration option, I find that the class javax.persistence.Entity has but one property,
String name() default "";
@Target(TYPE) @Retention(RUNTIME) public @interface Entity { String name() default ""; AccessType access() default PROPERTY; }
OK, so I found the right new EJB3 spec and it is intentionally removed - sorry for the post.
