Hi Thank you for your reply. I have already a book named Pro hibernate 3.0, In that book author said that hibernate 3.0 does not support generating schema from annotated class. and it just generate database from mapping files. Now i learned that a ANT task helps to generate schema from mapping files. what i want to know is about ant task or a solution for generating schema from annotated classes. So, is there any ant task for this? Thanks View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3986871#...
