没有注册驱动
Class.forName(...);

给你一个我做过的例子的一部分
public static final String DRIVER="com.microsoft.sqlserver.jdbc.SQLServerDriver";
public static final String URL="jdbc:sqlserver://localhost:1433;databaseName=company";
public static final String DBNAME="sa";
public static final String DBPASS="";

/**
* 得到数据库连接
* @return
*/
public Connection getConn(){
Connection conn=null;
try {
Class.forName(DRIVER); //注册驱动
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

try {
conn=DriverManager.getConnection(URL,DBNAME,DBPASS);//连接数据
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

return conn;
}

Connection con;
Statement sql;
ResultSet rs;
