If i try the following:

<property name="openjpa.Sequence"
value="org.apache.openjpa.jdbc.kernel.ClassTableJDBCSeq"/>


1221  embeddables  ERROR  [main] openjpa.Runtime - Failed to create a
provider for "embeddables".
java.lang.RuntimeException: There were errors initializing your
configuration: java.lang.ClassCastException:
org.apache.openjpa.conf.OpenJPAConfigurationImpl cannot be cast to
org.apache.openjpa.jdbc.conf.JDBCConfiguration

If I try to do like this:

System.setProperty("ConnectionDriverName", "org.hsqldb.jdbc.JDBCDriver");
     System.setProperty("ConnectionURL", "jdbc:hsqldb:mem:persist_backend");
        EntityManagerFactory emf =
Persistence.createEntityManagerFactory("embeddables",
System.getProperties());
        EntityManager em = emf.createEntityManager();
        init(em);
        runQueries(em);

following exceptions are thrown:

Manual setup, like the one recommended:
JDBCConfiguration conf = new JDBCConfigurationImpl();
     conf.setConnectionDriverName("org.hsqldb.jdbc.JDBCDriver");
     conf.setConnectionURL("jdbc:hsqldb:mem:persist_backend");
        TableJDBCSeq seq = new TableJDBCSeq();
        seq.setConfiguration(conf);
     EntityManagerFactory emf =
Persistence.createEntityManagerFactory("embeddables",
System.getProperties());
        EntityManager em = emf.createEntityManager();
        init(em);
        runQueries(em);

caused following:
