Maven Plugin and schema tools

I am a bit confused about maven plugin. Trying to create tables
directly from the Entities classes.

I know it can create a schema definition and produce xml file or sql
file, but is there a way to generate and write the schema directly to
the DB ?

This functionality is not hard to add to maven plugin, but if it
exist, I prefer to use it.

The plugin I am talking about
http://mojo.codehaus.org/openjpa-maven-plugin/index.html

Thank you.
