Question

我是一名java开发人员，我正在研究基于Java的Web应用程序项目。我们正在使用tomcat 7.0.40应用程序服务器。由于我将应用程序迁移到jsr299提供的jboss-weld 1.1.10.Final支持，因此我在tomcat上部署应用程序时遇到了麻烦。

出于安全原因，我不会在生产服务器上爆炸部署的WAR。在预生产测试中，我注意到因为server.xml中的unpackWARs=false而导致异常。

如果我在本地服务器上将此属性更改为unpackWARs=false，则会出现相同的异常。否则（在本地和预生产服务器中均使用unpackWARs=true），应用程序可以正常工作。

以下是异常：

com.sun.faces.lifecycle.ProcessValidationsPhase execute

框架，我正在使用：

Tomcat 7.0.40（无Java-EE堆栈）
JBoss-Weld：org.jboss.weld.servlet 1.1.10.Final
Apache Myfaces CODI扩展：org.apache.myfaces.extensions.cdi.core和jsf-module，v1.0.3
JSF impl。 Mojarra v2.1.7
JSF Richfaces组件库，v4.3.0.Final

Target Unreachable, identifier resolved to null - 如果JSF Unified-EL中存在一些错误拼写以访问bean属性，或者beans.xml放错了位置，则会经常发生异常。但是它们不适用于我，因为应用程序适用于unpackWARs=true。

非常感谢您对此事的关注。亲切的问候，abertschi

server.xml（tomcat，我没有更改任何其他属性）：

ichchumenöddusus。 z vill Infos。 Rüefmichmal，wänns问题nöchstmalvorchunnt。好的，jetzt chumi drus。施拉格... 简而言之：当部署打包为war（unpackWar = FALSE）时，应用程序无法访问某些bean。我会在下次发生时查看您的设置。

具有unpackWARs =“false”的Tomcat无法部署基于CDI Weld的应用程序
