【问题描述】：
在我的网络应用程序中，我尝试使用自定义错误页面。
但是，这不适用于 Weld。当我导航到应用程序中不存在的页面而不是获取自定义错误页面时，我看到 Weld 出现异常：

我认为这是 Tomcat 中的错误：
https://issues.apache.org/bugzilla/show_bug.cgi?id=50789
但它已在 v.7.0.9 中修复
摘自我的web.xml：
<error-page>
<exception-type>java.lang.Exception</exception-type>
<location>/pages/error.xhtml</location>
</error-page>
<error-page>
<error-code>500</error-code>
<location>/pages/error.xhtml</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/pages/pageNotFound.xhtml</location>
</error-page>
我正在使用 Tomcat 7.0.19、JSF 2.0 和 Weld 1.1.2。
有什么想法会发生什么？
【问题讨论】：

我认为原因是 RequestScoped 的上下文未激活。我一直在用 seam-wicket 解决类似的问题，最后，我通过重写 seam-wicket 从我的应用程序中放弃了对 @RequestScoped 的支持。但是，这可能不是您想要使用 JSF 做的事情。这适用于weld + JSF 集成开发人员。无论如何，您没有在类路径中添加weld-se-core 吗？
