Får en JBossTransactionRolledbackException ?

Når jeg forsøger at hente data ind fra db får jeg denne exception. Forespørgslen går fra en klient til en stateless bean som så kalder en CMP bean. Jeg har lagt source ud på min hjemmeside, hvis nogen skulle være interesseret i at hjælpe. Kør ant får at få genereret mapperne:
