First migrate your database from hibernateSQl to Mysql. then you have to made one change in development.resources after starting the jetty from blPU.hibernate.hbm2ddl.auto=create-drop
to blPU.hibernate.hbm2ddl.auto=update
if it doesnt works then you have to setup your whole demosite in tomcat server by just delpoying the .war file of your project in tomcat webapp folder.
and do the same changes in development.properties after starting the tomcat ..
It will surely work for you.
