Well. I think it depends. I know that if you use the hibernate provider that you can set a property to automatically create/update the schema when it runs. You can look at the JPA Demo site in the Lift repo:
http://github.com/dpp/liftweb/blob/794cac5abf6b1ae5502f6321847f6186fcd8de90/sites/JPADemo/JPADemo-spa/src/main/resources/META-INF/persistence.xml The relevant property is "hibernate.hbm2ddl.auto" I haven't used TopLink but it appears to have a subset of this functionality: http://www.oracle.com/technology/products/ias/toplink/JPA/essentials/toplink-jpa-extensions.html#Java2DBSchemaGen The caveat is that with Hibernate it can alter existing tables to match changes in your entities, but toplink appears to do a drop-then-add, which kind of sucks. I haven't looked at JPOX or any other JPA impls.
