Hello,

I encounter NullPointerException when trying to get list of a table elements.
Mean that createQuery return Null but don"t understand why

Thanks.

Hibernate: select playerinfo0_.Id as Id73_, playerinfo0_.Name as Name73_, playerinfo0_.HistoryScore as HistoryS3_73_, playerinfo0_.Credits as Credits73_ from Player playerinfo0_
2006-04-16 01:47:19,919 : JFactory.postInvoke : system exception in business method:
java.lang.NullPointerException



Here my call :

final List players = ssn.createQuery("from PlayerInfo").list();
