JDBC如何连SQL

JDBC怎么连SQL~
谁会用JDBC与SQL2005连.!
 3个包莪下了.担不知道怎么导.!
 而且莪的工具还是英文的~JBuilder 2005~找不到汉化包.!跪求高手指点吖!!!!

莪的SQL是2005的.~以下是代码 
Connection con; 
  Statement st; 
  ResultSet rs; 
  String url = "jdbc:microsotf:sqlserver://"; 
  String serverName = "localhost"; 
  String portNumber = "1433"; 
  String databaseName = "test"; 
  String userName = "sa"; 
  String password = "123456"; 
  public Conn() { 
  } 


  String getconn() { 
  return url + serverName + ";" + portNumber + ";databaserName=" + 
  databaseName + ";"; 
  } 

  Connection getCon() { 
  try { 
  Class.forName("com.microsoft.jdbc.sqlserver.SQLServerDriver"); 
  con = DriverManager.getConnection(getconn(), userName, password); 
  if (con != null) { 
  System.out.println("OK"); 
  } 
  } catch (Exception ex) { 
  ex.printStackTrace(); 
  System.out.println("getconn()Sorry" + ex.getMessage()); 
  } 
  return con; 
  } 
下面是报错代码:
