java - Hibernate vs EclipseLink -


i'm starting new web project , i've chosen jpa persistence orm engine.

although i've used openjpa in last project, want use eclipselink.

why? jpa reference implementation, has lot of documentation , support in eclipse ide. also, can't found benchmark declares none of them best, performance not factor (all implementations has own strength points).

but, want use jsr-303 validation spec, , i've chosen hibernate-validator (witch reference implementation of bean validation spec).

moreover, i'm using spring, , there lot of examples spring+hibernate, haven't found opinion said spring better hibernate.

is there problem mixing 2 implementations? better use hibernate jpa hibernate bean validation?

i have been using eclipselink implementation of jpa spring , hibernate-validation-4.2.0.final. , no problem far. answer question:

is there problem mixing 2 implementations?

i don't think there problem using eclipselink jpa implementation hibernate implementation jsr-303 validation spec together, purpose of these 2 specifications different:

  • jsr 303 - bean validation - defines metadata model , api entity validation. not tied specific application tier or programming model.
  • jpa - specification of java api management of persistence , object/relational mapping java ee , java se.

spring provides full support jsr-303 bean validation api. need have jsr-303 provider, such hibernate validator, present in classpath , detected automatically.

and spring jpa, available under org.springframework.orm.jpa package, offers comprehensive support java persistence api in similar manner integration hibernate.
