No it is not. You can go from the outside in, the inside out, or meet in the middle.
I have known people who defined the schema strictly from ORM annotations and used Hibernate's ability to instantiate tables on startup. For myself, I usually inherit an existing database, so I have to reverse-engineer at the beginning. Traditionally I've used OpenJPA's tools for that, but that's because before JPA was a standard I worked with Kodo JDO and the OpenJPA tools are descended from the JDO tools, so I'm comfortable with them.
