Initializing database

[jcv]

Hi, i'm playing a little bit with jbpm engine and i've made some changes to the hibernate database definition. How can i reflect this changes on the database creation?

If you mean that you'd like to create the database automatically that's easy. You can tell hibernate to do the job for you. See

http://wiki.jboss.org/wiki/Wiki.jsp?page=UseHibernateToCreateJbpmDB

for details on how to do that. Otoh, if you want to update your existing database to reflect changes you've made in the mappings and code, you'll have to check to see whether hibernate's automatic schema creation supports changes. I'm not sure about that, and if so, I suspect it's limited support. Probably better to add/remove columns yourself.
