HI Chris, It sounds like you are having mixed luck... It's difficult when things are not consistent... :-)
Let's assume the classloader issue is no longer applicable. Are you experiencing the JPQL issues with the 2.0 Beta? Or, with the 1.2.x code base? Catalina had originally replied that one of your JPQL issues was not defined by JPA 1.0, but was defined in JPA 2.0. So, I'm just clarifying your environment. Thanks for your patience. We'll get to the bottom of your questions soon.
