关于 MyEclipse 用jtds连接sql server 2000

 求助:
   MyEclipse (用jtds连接)sql server 2000(安装在E盘) 就是连不上!  我用的MyEclipse是5.5 jtds是1.2  数据库 sp4 补丁已经打上 ,问:还要不要打其他的补丁?
   代码:
   public class DatabaseOpe {
 static Logger log = Logger.getLogger(DatabaseOpe.class);

 public Connection getConnection() throws SQLException {

  try {
   Class.forName("net.sourceforge.jtds.jdbc.Driver");
   log.debug("数据库驱动创建成功！");
  } catch (ClassNotFoundException e) {
   log.error("数据库驱动创建失败！", e);
  }

  java.sql.Connection mycon = null;

  String url = "jdbc:jtds:sqlserver://localhost:1433/news_project";
  log.debug("url:" + url);
  try {
   mycon = DriverManager.getConnection(url, "sa", "");
   log.debug("数据库连接成功！");
  } catch (SQLException e) {
   e.printStackTrace();
   log.error("数据库连接异常", e);
   throw e;
   //e.printStackTrace();
  }
  return mycon;
 }
