I am getthing the error:
Unable to deploy EJB: sempire_bc.jar from sempire_bc.jar:
Error while reading 'META-INF/weblogic-cmp-rdbms-jar.xml'. The error
was:
The finder method findAllOrderByRoleName of ejb RolesEJB cannot have
a null ejb ql value.
The finder method findAllOrderByUserName of ejb UsersEJB cannot have
a null ejb ql value.
This is my weblogic-cmp-rdbms-jar.xml file:
