运行简单EJB应用程序的问题

Question

我目前正在运行一个使用无状态会话Bean的简单EJB应用程序。我正在使用Personal Glassfish 3.0开发NetBeans 6.8，并在我的系统上安装了Java EE和Java SE。我不知道它是否是相关的，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出你好。当我尝试运行应用程序，我发现了以下错误：

服务器还显示此错误消息：

你认为是什么问题？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。看看你是否有任何错误。如果您在没有EJB的情况下出错，那么您的Glassfish安装有问题。

如果Glassfish在没有EJB的情况下正常启动，那么请发布您的EJB代码。 EJB代码可能存在一些问题。

Answer 2

用户Pascal Thivent非常友善地删除了包含此问题的答案的帖子，因为一些奇怪的和奇怪的原因。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的被扔了很多的警告，因为它被安装在一个目录，它的路径名有空间的“程序文件”。所以要解决这个问题，只需将它安装在C：/

2：关于抛出的NullPointerException（请参阅第一篇文章并向下滚动一下），似乎有一个问题，请参阅此链接https://glassfish.dev.java.net/issues/show_bug.cgi?id=11494 with glassfish和java6u18 。所以要解决这个问题，要么等待java在未来的更新中修复这个bug，要么降级到java6u17或更低版​​本。

希望这可能会有所帮助。
