Java Oracle 11g连接

我正在使用Oracle11g，并在类路径中设置了ojdbc6.jar。当我尝试使用以下代码连接数据库时：

//JdbcTest.java


import java.sql.*;
public class JdbcTest
{
    public static void main(String args[])throws Exception
    {
        Class.forName("oracle.jdbc.driver.OracleDriver");
        Connection con = DriverManager.getConnection("jdbc:oracle:thin:@localhost:1521:orcl","scott","tiger");
        Statement st=con.createStatement();
        ResultSet rs = st.executeQuery("select * from dept");
        while(rs.next())
        {
            System.out.println(rs.getInt(1)+ " " + rs.getString(2) + " " + rs.getString(3));
        }

        rs.close();
        st.close();
        con.close();
    }
}`

我得到以下错误：

可能的重复更可能是的重复，因为您正在尝试连接到服务名称，所以需要使用服务名称语法
