no because in myeclipse you pointed to their DTP database connection, right ? for b9 you need to use a different cfg.xml since it is not possible to use jboss local datasources from within eclipse. In nightly build (and possibly alson in b9 but i havent tested) you can specify a hibernate.properties or any other properteis file and specify normal connection properties to override what is in your Appserver specfic setup.
