我是Glassfish的新手，我已经发现Glassfish 4.1.1（我猜4.1）有一个错误。谷歌搜索后我解决了这个问题，并更新到Glassfish 4.1.2。现在，我在部署应用程序时遇到以下异常和堆栈跟踪：

Severe: Exception while deploying the app [DHWear-1.0] : Failue while processing glassfish-resources.xml(s) in the archive -- E:\Program Files\glassfish4\glassfish\domains\randomlogic\applications\DHWear-1.0\DHWweb-1.0_war\WEB-INF\lib\DHWbean-1.0.jarMETA-INF\glassfish-resources.xml (The system cannot find the path specified)
无论是使用NetBeans 8.2进行部署还是使用Glassfish Web管理控制台，都会发生此异常。
这个错误对我和它显示的路径毫无意义：
E:\Program Files\glassfish4\glassfish\domains\randomlogic\applications\DHWear-1.0\DHWweb-1.0_war\WEB-INF\lib\DHWbean-1.0.jarMETA-INF\glassfish-resources.xml
对我来说很奇怪。这部分：
\DHWbean-1.0.jarMETA-INF\
似乎某些内容被错误地解析了。在我看来它应该是：
\DHWbean-1.0.jar\META-INF\
查看存档，我看到了路径
\DHWear-1.0\DHWweb-1.0_war\WEB-INF\lib\DHWbean-1.0.jar\META-INF\glassfish-resources.xml
确实存在。
无论如何，有没有人遇到过这个问题，如果有的话，我该如何解决？
更新
我发现部署WAR文件没有显示此错误，并且发现NetBeans根本没有配置Glassfish JDBC资源（显然是一个开放的bug - 很有趣它与Tomcat服务器一起工作）。我手动将资源添加到服务器以解决该问题，但EAR仍然无法正常工作。
我从三个持久性单元模块中删除了glassfish-resources.xml个文件，并将内容合并到一个带有应用程序范围的glassfish-resources.xml文件中。这解决了EAR的问题，但现在当我部署EAR或WAR时，我得到了：
Severe: Exception while preparing the app
java.lang.NullPointerException

我不知道为什么。
答案 0 :(得分：0)
事实证明，答案是由于各种原因，Glassfish可能无法正确连接到数据源。原因可能会因数据库服务器丢失网络连接，身份验证失败等原因而有所不同。结果是无意义的异常，而不是明确的消息，指出数据源存在问题。我认为这是Eclipselink中的一个错误，至少，它不应该抛出异常而不提供某种线索，为什么，或理想地说明发生了什么。
