java - Hibernate Query for unmapped join table -

i'm j2ee newbie trying learn hibernate. have 2 tables, system , game, , join table called systems_game.

i want able put in game_id , of systems game.

i using annotations on system.java , game.java create many-to-many relationship.

@manytomany(targetentity = system.class, cascade = { cascadetype.all }) @jointable(name="systems_game",             joincolumns = { @joincolumn(name="game_id") },             inversejoincolumns = { @joincolumn(name="system_id") }) private list<game> games; 

and here method using try result want.

@override public list getgamesystem(){     return sessionfactory.getcurrentsession().createquery("from systems_game s s.game_id=1").list();               } 

when runs, get
"request processing failed; nested exception org.hibernate.hql.ast.querysyntaxexception: systems_game not mapped [from systems_game s s.game_id=1]"

i know don't have systems_game mapped in hibernate.cfg.xml file, don't know how map since don't have class it. need many-to-many relationship different way , give it's own class? other way overlooking me achieve desired result?

if need more code post.

2 ways this:

1. sql way:

   sessionfactory.getcurrentsession().createnativequery("select * systems_game s s.game_id=1")...

2. hibernate(java) way:

   game = session.createquery(from game id = 1).uniqueresult() list systems = game.getsystems()

just try pseudocode！
