Hi guys!

I am a little confused about these QL. I'm about to start an application and I don't know wich one to use. Can someone point some differences about them, articles anything..?Is JPQL the same as EJBQL?

JPQL is for EJB 3.0 (J2EE 5). EJBQL is for EJB 2.1 (J2EE 1.4 and below.) So which one you choose depends on what version of J2EE/EJB you are using.
