trying to access db which is having array of double for which i hav written user type class:::

    @Override

        Array array = rs.getArray(names[0]);
        Double[] javaArray = (Double[]) array.getArray();
        return ArrayUtils.toPrimitive(javaArray);
    }

    @Override
    public void nullSafeSet(final PreparedStatement statement, final Object object, final int i, final SessionImplementor sessionImplementor) throws HibernateException, SQLException {
        Connection connection = statement.getConnection();

        double[] castObject = (double[]) object;
        Double[] doubles = ArrayUtils.toObject(castObject);
        Array array = connection.createArrayOf("DOUBLE", doubles);

        statement.setArray(i, array);
    }

    @Override
    public Object assemble(final Serializable cached, final Object owner) throws HibernateException {
        return cached;
    }

    @Override
    public Object deepCopy(final Object o) throws HibernateException {
        return o == null ? null : ((double[]) o).clone();
    }

    @Override
    public Serializable disassemble(final Object o) throws HibernateException {
        return (Serializable) o;
    }

    @Override
    public boolean equals(final Object x, final Object y) throws HibernateException {
        return x == null ? y == null : x.equals(y);
    }

    @Override
    public int hashCode(final Object o) throws HibernateException {
        return o == null ? 0 : o.hashCode();
    }

    @Override
    public boolean isMutable() {
        return false;
    }

    @Override
    public Object replace(final Object original, final Object target, final Object owner) throws HibernateException {
        return original;
    }

    @Override
    public Class<double[]> returnedClass() {
        return double[].class;
    }

    @Override
    public int[] sqlTypes() {
        return new int[] { SQLTYPE };
    }
}

but it is giving error as:::

Hibernate does not supportsdatabase arrays(e.g.java.sql.Array)

arrayandprimitive-arraytypes provided by Hibernate are for mapping Java arrays into backing table - they're basically a variation of one-to-many / collection-of-elements mappings.

Here, is anexamplefor Postgresql in which @Alex have sorted out this problem by himself using theUserType for integer arrays. Also, thisexampleis related to mapping a postgres array with hibernate.
Hope this helps.
