SVN trunk allows the following

import org.datanucleus.metadata.PersistenceUnitMetaData;
import org.datanucleus.api.jpa.JPAEntityManagerFactory;


PersistenceUnitMetaData pumd = new PersistenceUnitMetaData("dynamic-unit", "RESOURCE_LOCAL", null);
pumd.addProperty("javax.persistence.jdbc.driver", "org.hsqldb.jdbcDriver");
pumd.addProperty("javax.persistence.jdbc.url", "jdbc:hsqldb:mem:nucleus");
pumd.addProperty("javax.persistence.jdbc.user", "sa");
pumd.addProperty("javax.persistence.jdbc.password", "");
pumd.addProperty("datanucleus.autoCreateSchema", "true");

EntityManagerFactory emf = new JPAEntityManagerFactory(pumd, null);
