“加载应用时异常”没有堆栈跟踪 [英] "Exception while loading the app" without a stack trace

问题描述

我将我的应用程序从GlassFish 3.0.1迁移到GlassFish 3.1.1。部署失败，并显示以下错误消息：

 严重：加载应用程序时异常
 SEVERE：关闭时异常应用程序容器
 SEVERE：关闭应用程序容器时异常：java.lang.NullPointerException 
 SEVERE：java.lang.RuntimeException：部署期间发生错误：关闭应用程序容器时出现异常：java.lang.NullPointerException。有关详细信息，请参阅server.log。 
  

没有堆栈跟踪。我打开根日志记录级别到FINEST，第一个SEVERE消息发生在Weld消息之后：

  // ... 
 FINE：WELD-000105启用管理员的拦截器类型
已启用备选方案：[] [] 
注册上下文：[interface javax.enterprise.context.SessionScoped，interface javax.enterprise.context.RequestScoped ，接口javax.inject.Singleton，接口javax.enterprise.context.Dependent，接口javax.enterprise.context.ApplicationScoped，接口javax.enterprise.context.ConversationScoped] 
注册的bean：0 
专业bean： 0 
：[] 
  

在几个类似这样的消息之前（对于几个不同的类）：

  FINE：PWC4451：无法读取文件/opt/sun/glassfish-3.1.1/glassfish/domains/domain1/applications /QmsWeb/WEB-INF/classes/org/jboss/seam/transaction/SeamT​​ransaction.class 
 FINE：PWC4451：无法读取文件/opt/sun/glassfish-3.1.1/glassfish/domains/domai n1 / applications / QmsWeb / WEB-INF / classes / org / jboss / seam / transaction / SeamT​​ransaction.class 
 FINE：PWC4451：无法读取文件/opt/sun/glassfish-3.1.1/glassfish/domains/ domain1 / applications / QmsWeb / WEB-INF / classes / net / sf / ehcache / config / TerracottaConfiguration $ ValueMode.class 
 // ... 
  

可能会导致此错误？这些PWC4451消息是否指示某些库未被加载？

解决方案

这是由于一个@ViewScoped bean不实现Serializable。显然，我们使用的较旧版本的Weld并没有发现令人厌恶的是，钝化范围的bean不是可序列化的，但是由于这个原因，这个bean无声地失败了。哦，希望这样可以节省一些时间。

I'm migrating my app from GlassFish 3.0.1 to GlassFish 3.1.1. Deployment fails, with the following error messages:

SEVERE: Exception while loading the app
SEVERE: Exception while shutting down application container
SEVERE: Exception while shutting down application container : java.lang.NullPointerException
SEVERE: java.lang.RuntimeException: Error occurred during deployment: Exception while shutting down application container : java.lang.NullPointerException. Please see server.log for more details. 

There is no stack trace. I turned on the root logging level to FINEST, and the first SEVERE message occurs after a Weld message:

//...
FINE: WELD-000105 Enabled interceptor types for Manager
Enabled alternatives: [] []
Registered contexts: [interface javax.enterprise.context.SessionScoped, interface javax.enterprise.context.RequestScoped, interface javax.inject.Singleton, interface javax.enterprise.context.Dependent, interface javax.enterprise.context.ApplicationScoped, interface javax.enterprise.context.ConversationScoped]
Registered beans: 0
Specialized beans: 0
: []

And before several messages like these (for several different classes):

FINE: PWC4451: File cannot be read /opt/sun/glassfish-3.1.1/glassfish/domains/domain1/applications/QmsWeb/WEB-INF/classes/org/jboss/seam/transaction/SeamTransaction.class
FINE: PWC4451: File cannot be read /opt/sun/glassfish-3.1.1/glassfish/domains/domain1/applications/QmsWeb/WEB-INF/classes/org/jboss/seam/transaction/SeamTransaction.class
FINE: PWC4451: File cannot be read /opt/sun/glassfish-3.1.1/glassfish/domains/domain1/applications/QmsWeb/WEB-INF/classes/net/sf/ehcache/config/TerracottaConfiguration$ValueMode.class
//...

What could be causing this error? Could these PWC4451 messages be indicating that some libraries aren't being loaded?

解决方案

This was due to a @ViewScoped bean that did not implement Serializable. Apparently, an older version of Weld that we were using didn't find it objectionable that a passivating-scoped bean wasn't Serializable, but this one failed silently because of it. Oh well, hope this saves someone some time.
