【求助】debian下jap+PostgreSQL

loveglory

论坛里面有在debian下面开发jsp的吗？
请求帮助啊~
软件装完之后（jdk，tomcat，postgresql），网上找了一个jsp连接PostgreSQL的代码
一运行，却没有显示出数据库里面的内容
不知道是不是自己配置出现问题了……

首先肯定一点，tomcat的首页是可以看到的（那只猫猫）
但就是这个脸postgresql的jsp不能用
估计是数据库这里出问题
想看看有没有有经验的大虾帮忙解答~

错误信息如下：
HTTP Status 500 -

type Exception report

message

description The server encountered an internal error () that prevented it from fulfilling this request.
