前段时间我遇到了同样的问题，使用 .accdb 数据库。看起来 Java 6 很好地支持 .mdb 格式，但不太支持 .accdb 文件格式，或者至少它需要在 Windows 上安装 MS-Access 数据连接组件才能工作。

这可能是它无法在您的计算机上编译并在您的朋友计算机上编译的原因。

无论如何，我在 MSDN 上找到了它并且它有效。

class MyConnection 
{
  public static Connection getConnection() throws Exception 
  {
   Driver d = (Driver)Class.forName ("sun.jdbc.odbc.JdbcOdbcDriver").newInstance();
   Connection c = DriverManager.getConnection("jdbc:odbc:Driver={Microsoft Access Driver   (*.mdb, *.accdb)};DBQ=*.accdb");
return c;
}

您需要从 Microsoft 网站下载并安装“MS-Access 数据连接组件”才能正常工作。
