环境描述
win7 64位 Eclipse开发java ，该段程序是连接access数据库，数据源是stu.mdb
出错代码段
public Statement getConnection()
{
Connection con=null;
Statement stm=null;
String dburl="jdbc:odbc:Driver={Microsoft Access Driver (*.mdb, *.accdb)};DBQ=F:\\stu.mdb";
//64位下需安装access2010 64位版，否则报错java.sql.SQLException: [Microsoft][ODBC 统统程序管理器]
//F：\\是我放置数据源文件stu.mdb的目录
//32位下用String dburl="jdbc:odbc:driver={Microsoft Access Driver (*.mdb)};DBQ=F:\\stu.mdb";
try
{
String username="";
String password="";
Class.forName("sun.jdbc.odbc.JdbcOdbcDriver"); //反射机制，调用jdbc-odbc驱动
con=DriverManager.getConnection(dburl,username,password); //数据库建立连接
stm = con.createStatement();
}
catch(SQLException e){JOptionPane.showMessageDialog(null,e.getMessage(), "出错",JOptionPane.ERROR_MESSAGE);}
// System.out.println(e.getMessage());
catch(ClassNotFoundException ex){JOptionPane.showMessageDialog(null,ex.getMessage(), "出错",JOptionPane.ERROR_MESSAGE);}
//System.out.println(ex.getMessage());
return stm;
}
报错如下

最新版本jdk，sun.security.action中没有 LoadLibraryAction.class，要到哪里去找这个类呢？另外这个类是怎么用到的呢？
