javax.ejb.FinderException: Unknown query

[tok199hz]

Hi all,
I'm new on JBoss so hope you can help me. I'm trying to upgrade a web application from JBoss 2.4 to 4.0.5 but seem's the application does'nt find query. Is it because on 2.4 is used jaws.xml file and 4.0.5 doesn't accept it?
Exist a way to use jaws.xml or have I to rewrite all queries in ejb-jar.xml?

Thanks all!!

sorry, in a better way:

I am migrating from JBoss 2.4 to 4.0.5. All my entity beans were working fine with jaws.xml under JBoss 2.4. Now when i try to deploy the same beans under JBoss 4.0.5 the deployment does not give any error but when i try to invoke any finder method it gives "javax.ejb.FinderException: Unknown query".
