报错内容如下：
Listener refused the connection with the following error:
ORA-12519, TNS:no appropriate service handler found
The Connection descriptor used by the client was:
localhost:1521:XE
请问如何解决？谢谢各位赐教

show error;看一下

嗯？什么意思哦？初学菜鸟，很多专业术语不懂。
我运行这个程序的时候就是报错如下：
Listener refused the connection with the following error:
ORA-12519, TNS:no appropriate service handler found
The Connection descriptor used by the client was:
localhost:1521:XE
就是用jdbc去连接数据库的时候的出错
