具体错误是
java.sql.SQLException: Listener refused the connection with the following error:
ORA-12518, TNS:listener could not hand off client connection
The Connection descriptor used by the client was:
192.168.1.100:1521:bjpowernode.com

这是我的java代码

public class conn {
public static void main(String []args){
Connection ct=null;
Statement sm=null;
ResultSet rs=null;
try {
Class.forName("oracle.jdbc.driver.OracleDriver");
ct=DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.100:1521:bjpowernode.com","system","tclwaasdngpai");
sm=ct.createStatement();
rs=sm.executeQuery("select * from scott.emp");
while(rs.next()){
System.out.println(rs.getString(2));
}
} catch (Exception e) {
e.printStackTrace();
}finally{
try {
if(rs!=null)rs.close();
if(sm!=null)sm.close();
if(ct!=null)ct.close();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

}

Net Configuration Assistant 我测试通过了端口也打开了服务也开了为啥就连接不上呢
求大虾们看看啊
