我的问题只发生在Jelast云服务器节点上，而不是本地计算机上

我做了以下工作：

我已经将mysql jar驱动程序上传到glassfish的
```
lib
```
文件夹中
我已创建连接池，ping已成功
我创建了数据源

但当我运行以下JSP时：

<%@page import="java.io.Writer"%>
<%@page import="javax.sql.DataSource"%>
<%@page import="java.sql.Connection"%>
<%@page import="javax.naming.InitialContext"%>
<%@page import="javax.naming.Context"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
  <head>
    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
    <title>JSP Page</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    <%
    InitialContext ctx = new InitialContext();
    DataSource ds = (DataSource)ctx.lookup("jdbc/rook-server");
    Connection conn = ds.getConnection();
    %>
  </body>

我来自Jelast团队。我们现在正在分析这个问题。我们找到原因后会通知你的。尝试重新启动GlassFish，也许这会有所帮助。当做

我的Jelast试用账户也有同样的问题。不知怎的，几天后他们/我就开始工作了。不知道原因是什么，很可能是服务器配置问题——用户无法控制的问题。Jelast支持论坛也有一些关于这个主题的帖子。如果你试着在那里问你的问题，也许你会得到更多的帮助（尽管有时这里会有一个Jelast支持团队成员）。分析的结果是什么？
