[jboss-user] [Persistence, JBoss/CMP, Hibernate, Database] - how to do a subquery in JBoss?

Hi, all now, I need to do a subquery like this: SELECT OBJECT(a) FROM SelectedRecs a WHERE a.sID2 IN (SELECT b.SID2 FROM SessionView b WHERE (b.LocalIP='213.114.83.134' AND b.RmtIP='137.72.43.114') OR (b.LocalIP='137.72.43.114' AND b.RmtIP='213.114.83.134')) note that: SessionView is another table. now I just write an entitybean for table SelectedRecs, not for it. when I run the demo using the EJB-QL above, it met some problems. so I wanna know how to do a subquery in JBoss, and the subquery is from another table. please give me a suggestion, thanks a lot. my msn is: qixiangnj AT gmail DOT com.
