Eclipse 之外的 Tomcat 6 上的 JSF PropertyNotFound 异常

【问题标题】：JSF PropertyNotFound Exception on Tomcat 6 outside of EclipseEclipse 之外的 Tomcat 6 上的 JSF PropertyNotFound 异常
【发布时间】：2013-08-31 17:14:12
【问题描述】：

我有一个应用程序可以在 eclipse 中的 tomcat 6 上完美运行。当我使用这个应用程序并将其手动部署到 eclipse 之外的同一个 tomcat 服务器并运行它时，我在尝试访问许多页面时得到javax.el.PropertyNotFoundException。

在 Eclipse 之外运行应用程序时，我如何获得PropertyNotFoundException，而不是在 Eclipse 中？

尝试访问页面时的堆栈跟踪：

【问题讨论】：

  • 你是如何在 Eclipse 之外迁移到 tomcat 的？你确定你拿了最新的课程文件吗？
  • 好吧，显然 WAR 构建失败和/或您没有运行您认为正在运行的代码？
  • 在 Eclipse 中使用 maven install 构建战争时没有错误。

【解决方案1】：

javax.el.PropertyNotFoundException: /ccadmin/publications/search.xhtml @107,92 value="#{pubBacker.beginYear}": Property 'beginYear' not found on type com.ccadmin.backing.PublicationBacker 明确指出它缺少beginYear bean 的beginYear 属性。

检查 jar 是否更新。这是常见的错误，至少对我来说。部分代码更新了，jar没有更新(mvn install)。

【讨论】：

  • 我不确定如何检查war文件是否已更新。它在 Eclipse 中使用 maven install 构建得很好
  • 我的 WEB-INF 目录中有一些 .class 文件一定是从其他人那里提交到 repo 的，它们一定是覆盖了用相同文件创建的新 .class 文件名字。
