    public static void main(String[] args) throws SQLException  {
        Connection conn=DriverManager.getConnection(
                "jdbc:ucanaccess://C:\\TESTFILE\\Database11.accdb");
        Statement s = conn.createStatement();
        ResultSet rs = s.executeQuery("SELECT * FROM myTable");

UCanAccess 使用 Jackcess，而 Jackcess 使用 commons-lang (v2.x)，而不是 commons-lang3。 UCanAccess 所需的所有依赖项均包含在 UCanAccess 发行版的 lib 文件夹中(.bin.zip 文件)。
