Question

我们的项目在Jetty服务器上并完全工作，然后这个项目部署在Jboss 7服务器上，但是有一些错误。

我制作war文件并在E:\jboss-as-7.1.1.Final\standalone\deployments文件夹中复制并过去并自动部署成为启动并发出此错误：

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

但在\WEB-INF\lib我有mail.jar文件..

那么如何删除此错误？

细节错误：

请帮忙，如何删除此错误？

谢谢，

Answer 1

JBoss AS 7带有隔离的类加载，因此您应该仔细配置项目依赖项。详细信息为here。

在你的情况下，我看到Spring引用了由JBossAS提供的Log4j：Module "org.apache.log4j:main"，并尝试将其配置为执行异常操作（可能尝试通过电子邮件进行日志记录）。问题是log4j模块无法访问mail-api，所以它会抱怨。

现在您至少有3个解决方案：

让Spring只使用log4j而不尝试配置它。而是在app-server级别配置log4j。见this。询问Spring专家如何做到这一点：）
将log4j.jar放入/ WEB-INF / lib中，不要将Module "org.apache.log4j"公开给您的网络应用程序。
将mail-api暴露给log4j模块并从你的应用程序中删除/WEB-INF/lib/mail.jar。您必须编辑jboss-as-7.1.1.Final/modules/org/apache/log4j/main/module.xml以包含对mail-api的依赖：
```
<dependencies>
    <module name="org.dom4j" optional="true"/>
    <module name="javax.api"/>
    <module name="javax.mail.api" export="true"/>
</dependencies>
```

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