在Jboss 7中部署时间错误（java.lang.NoClassDefFoundError：javax/mail/internet/AddressException）

Question

我们的项目在Jetty服务器上并且完全工作，然后该项目部署在Jboss 7服务器中，但出现了一些错误。

我发动战争文件，复制和过去E:\jboss-as-7.1.1.Final\standalone\deployments文件夹，并自动部署变得开始，让这个错误：

java.lang.NoClassDefFoundError: javax/mail/internet/AddressException 

但\WEB-INF\lib我的mail.jar文件..

那么如何删除此错误？

细节错误：

所以请大家帮忙，如何删除这个错误？

感谢，

Answer 1

JBoss应用服务器7配备了独立的类加载，所以你应该仔细配置项目的依赖。详情是here。

在你的情况下，我看到Spring引用了JBossAS提供的Log4j：Module "org.apache.log4j:main"，并试图将其配置为执行一些不寻常的事情（可能试图通过电子邮件进行日志记录）。问题是mail-api不能被log4j模块访问，所以它抱怨。

现在你至少有3个解决方案：

1. 制作春只是使用log4j的，但不尝试对其进行配置。应该在应用程序服务器级别配置log4j。见this。询问Spring专家如何去做:)

2. 把log4j.jar放到你的/ WEB-INF/lib目录下，并且不要将Module "org.apache.log4j"暴露给你的webapp。

3. 将mail-api公开到log4j模块并从您的应用程序中删除/WEB-INF/lib/mail.jar。你将不得不编辑jboss-as-7.1.1.Final/modules/org/apache/log4j/main/module.xml包括对邮件的API的依赖：

   <dependencies> 
       <module name="org.dom4j" optional="true"/> 
       <module name="javax.api"/> 
       <module name="javax.mail.api" export="true"/> 
   </dependencies>
