【问题描述】：

我配置了我的 Tomcat 环境，并成功地将 ADF Essentials 部署到使用 Jdeveloper11.1.2.4 开发的 Tomcat6.x 上。

现在我正在尝试将使用 Jdeveloper12c 开发的示例 ADF Web 应用程序（仅包含一个带有按钮的页面）部署到 Tomcat 6.x 和 Tomcat 7.X 上。在两台服务器上都出现以下异常

type Exception report

在此之后，我从该页面中删除了按钮，并添加了一个<af:outputText value="outputText1" id="ot1"/>。现在这个页面已经在Tomcat7.x上成功运行了。

请帮助我。提前问好。

【问题讨论】：

在 Tomcat 上部署时，您的标签库似乎比与您的 Weblogic 部署对应的版本旧一个版本。 af:button 是最新 ADF 版本附带的标签，而 af:outputText 已经存在了很多版本。

标签： jsf tomcat7 tomcat6 jsf-2.2 oracle-adf

【解决方案1】：

如果您使用的是 JDeveloper 11.1.x.x，则没有任何称为按钮的东西，它被称为 af:commandButton 或 af:goButton。

在 12c 中，这两个按钮已被替换为 af:button，根据其属性可以充当 af:commandButton 或 af:goButton。由于您从 12c 降级到 11g，因此您需要处理这些并使用等效按钮。 af:commandButton 和 af:goButton 在 12c 中也适用于向后兼容，因此您应该可以将它们与 12c 一起使用，尽管不推荐。
