¿Cómo puedo usar JDBC para copiar el esquema de una base de datos a otra sin usar Apache DDLUtils?

Escribí el código yo mismo, no resultó ser tan difícil. Esto es para generar el esquema a MySQL; No he probado FileMaker pero debería ser muy similar.

import java.sql.ResultSet;
import java.sql.SQLException;
