Your actual Hibernate JPA query would be quite easy, since all the joins are automatic in JPA.
But you didn't actually define a @ManyToMany relationship on anything there.
I appreciate your attempting to keep the code samples short, but if you could display more of the entity class definitions of GNRL_ORG_CHARGE_CODE, the join table GNRL_CHARGE_CODE_COND and the BILLING_CONDITION class, it would help a lot.
The things I need to see are the class definition line and its annotations, the joining annotations and the class member definitions for those joining annotations.
