运行简单 EJB 应用程序的问题

Question

我目前正在使用无状态会话 Bean 运行一个简单的 EJB 应用程序。我正在使用 Personal Glassfish 3.0 开发 NetBeans 6.8，并且我已经在我的系统上安装了 Java EE 和 Java SE。我不知道这是否相关，但我正在运行 Windows7 64 位版本。我实现的 Session Bean 只有一个方法 sayHello();它只是在屏幕上打印你好。当我尝试运行应用程序时，出现以下错误：

服务器也显示此错误消息：

你认为问题是什么？这仍然是我的第一个 EJB 应用程序，所以我是这个 API 的新手。

Answer 1

删除所有 EJB 并重新启动 Glassfish 服务器。看看你是否得到任何错误。如果在没有 EJB 的情况下出现错误，则说明 Glassfish 安装有问题。

如果 Glassfish 在没有 EJB 的情况下可以正常启动，请发布您的 EJB 代码。 EJB 代码可能存在问题。

Answer 2

用户 Pascal Thivent 出于某种奇怪和奇怪的原因删除了包含此问题答案的帖子。所以我将不得不重新发布解决方案。

所以基本上解决方案是：

1：Glassfish 引发了很多警告，因为它安装在路径名有空格“Program Files”的目录中。所以要解决这个问题，只需要安装在C:/

2：关于被抛出的 NullPointerException（请参阅第一篇文章并向下滚动一点），似乎存在问题，请参阅此链接 https://glassfish.dev.java.net/issues/show_bug.cgi?id=11494 与 glassfish 和 java6u18。所以要解决这个问题要么等待java在以后的更新中修复这个bug，要么降级到java6u17或更低。

希望这可能会有所帮助。
