Weblogic + JPA + Hibernate = ClassNotFoundException: org.hibernate.hql.ast.HqlToken

9:52 am Java, Java EE, Programação

Ao tentar efetuar o deploy de uma aplicação com JPA (implementação: Hibernate), ocorre o seguinte erro:

org.springframework.orm.hibernate3.HibernateQueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [SELECT p FROM PARAMETRO p WHERE UPPER(RTRIM(p.parametroPK.parametroGeral)) = :parametroGeral AND UPPER(RTRIM(p.parametroPK.codigo)) = :codigo]; nested exception is org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [SELECT p FROM PARAMETRO p WHERE UPPER(RTRIM(p.parametroPK.parametroGeral)) = :parametroGeral AND UPPER(RTRIM(p.parametroPK.codigo)) = :codigo]

Para resolver este problema basta alterar o persistence.xml e adicionar a seguinte linha:

<property name="hibernate.query.factory_class" value="org.hibernate.hql.classic.ClassicQueryTranslatorFactory"/>
