No, absolutely not. :-)
1) iBATIS isn't an ORM in the strict definition sense.
2) I think JPA is a bad idea. It's a spec that should have never been written. Hibernate and TopLink were both great products without the JPA spec, and I don't see any benefit coming from the spec itself. If anything, it will damage one or both of those two frameworks in that the spec will cause them to: A) lose their competetive advantage by catering to the lowest common denominator, or B) totally break the spec to achieve a competetive advantage, which therefore makes the spec less useful or possibly even useless.
With EJB3.0 catching up and JPA being accepted as a spec by the application server vendors, wouldnt this mean that iBatis will not be considered for managing EJB3.0 entities by any of the appliaction servers.
