Re: [eclipselink-users] Preventing polymorphic selects in JPQL

[Tom Ware <tom.ware@xxxxxxxxxx>]

Hi Daniel,

  You can configure the InheritancePolicy on our ClassDescriptors not to read 
subclasses.  To do this, create a DescriptorCustomizer for the class you want to 
change the behavior of and call 
descriptor.getInheritancePolicy().setShouldReadSubclasses(false).
