Java hibernate how to use select ... where id in ()

I have Account class--account table mapping already.

Now I need use

from account where account_id in (select account_id from anothertable where...)

I got an error saying

org.hibernate.hql.ast.QuerySyntaxException: account is not mapped [from account where account_id in (select account_id from ano开发者_Go百科thertable where...)]

Any suggestions?

I should use CLASS NAME, not TABLE NAME. Thank you for your time anyway.
