“加载应用程序时出现异常"没有堆栈跟踪 [英] "Exception while loading the app" without a stack trace

问题描述

我正在将我的应用从 GlassFish 3.0.1 迁移到 GlassFish 3.1.1.部署失败，并显示以下错误消息:

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. 

没有堆栈跟踪.我将根日志记录级别打开为 FINEST，第一条 SEVERE 消息出现在 Weld 消息之后:

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
: []

在几条这样的消息之前(针对几个不同的类):

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
//...

是什么导致了这个错误?这些 PWC4451 消息是否表明某些库没有被加载?

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

推荐答案

这是由于 @ViewScoped bean 没有实现 Serializable.显然，我们使用的旧版本的 Weld 并没有发现钝化范围的 bean 不是 Serializable 令人反感，但是由于这个原因，这个版本无声无息地失败了.哦，好吧，希望这可以为某人节省一些时间.

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.
