Bom dia a todos,
è o seguinte, estou tentando fazer uma consulta com parametros posicionais, conforme código abaixo
String queryString = "select user from ?1 user";
String string = "User";
Query query = em.createQuery(queryString).setParameter(1, string);
mas é lançada a seguinte excessão
Exception in thread "main" java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: unexpected token: ? near line 1, column 18 [select user from ?1 user]
at org.hibernate.ejb.AbstractEntityManagerImpl.throwPersistenceException(AbstractEntityManagerImpl.java:624)

Estou utilizando a biblioteca do Hibernate - JPA, do netBeans 6.8
Alquem poderia me ajudar?
