Hi,

I use glassfish 2.1 in my developer environment and for the moment I develop an jsf-ejb-hibernate application.
I didn't find any solution to specify "parent-last" for the classloader and for this reason there are some conflicts between jars which are imported as dependencies by the Hibernate Validator 4.0.1 GA and Hibernate entity manager 3.4.0 GA.
I want to use Hibernate Validator v. 4 because is the implementation of the JSR 303.

The error which is thrown by the server is:
java.lang.AbstractMethodError: org.hibernate.ejb.HibernatePersistence.isLoadedWithoutReference(Ljava/lang/Object;Ljava/lang/String;)Ljavax/persistence/spi/LoadState;

at org.hibernate.validator.engine.ValidatorImpl.validateInContext(ValidatorImpl.java:213)
at org.hibernate.validator.engine.ValidatorImpl.validate(ValidatorImpl.java:119)

Is it possible to use both frameworks with the latest versions in the same time?
Or is the error thrown from other conflicts?

Thank you very much in advance

No.
It is definitely due incompatibility between Hibernate Validator 4.0.1 GA and Hibernate entity manager 3.4.0 GA.
This because Hibernate Validator 4.0.1 GA is for usage with JPA2 standard (jpa-api.jar is version 2.0.Beta-20090815)
whilst Hibernate entity manager 3.4.0 GA is for usage with JPA1 standard (ejb3-persistence.jar)


Not with the latest GA versions.
Hibernate Validator 4.0.1 GA should be compatible with Hiberante 3.5 which is currently in Candidate release status.
