线程主com.inet.ora.Ora3SQLException中的异常：[OraDriver] java.net.UnknownHostException：@localhost

Question

hi以下代码正在编译，但运行时错误为：

"Exception in thread main com.inet.ora.Ora3SQLException:[OraDriver] java.net.UnknownHostException:@localhost"

代码：

import java.sql.*;
class CreatingTable
{
    public static void main(String[] ar) 
        throws Exception{DriverManager.registerDriver(new com.inet.ora.OraDriver())
    Connection con= DriverManager.getConnection("jdbc:inetora:@localhost:1521:orcl","riya","java");
    Statement stmt=con.createStatement();
    int students=stmt.executeUpdate("create table class(name varchar2(20),rollno number(20)");
con.close();
}}

这里我使用了inet jdbc驱动程序，请有人为我解决这个问题....

Answer 1

尝试从localhost中删除@ "jdbc:inetora:localhost:1521:orcl"...
