在 Eclipse 中工作的 Web 应用程序给出验证 EL 错误 org.apache.catalina.core.StandardWrapperValve 调用
在 Tomcat 7 环境中的 Eclipse 中运行良好的标准 Web 应用程序会出现此错误。任何想法
应用程序在 eclipse 中运行良好....但 Tomcat 7 中的大量这些错误和应用程序没有响应

A standard webapp working well in Eclipse in a Tomcat 7 environment is giving this error. Any ideas
App runs fine within eclipse....but tons of these errors in Tomcat 7 and app is unresponsive

当您编译/构建 webapp/ 时,可能会发生这种情况针对生产环境中运行的容器不支持的 JSP/Servlet 版本进行 WAR。例如,您正在使用 Tomcat 7 进行开发,但最终将其部署到 Tomcat 6。确保目标运行时 servletcontainer 与您在 Eclipse 中开发的 servletcontainer 具有相同的 JSP/Servlet 版本。
如果动态 Web 模块版本与作为目标运行时的最大支持 Servlet API 版本匹配,请右键单击项目并检查项目方面属性。例如Tomcat 6.0仅支持Servlet 2.5。此外,您应该更喜欢针对与生产中运行的完全相同的 servletcontainer make/version 进行开发。然后可以在项目属性的“目标运行时”部分中进行设置。
您还应该确保 Web 应用程序的
/WEB-INF/lib
中没有任何特定于容器的库。另请参阅 如何导入 javax我的 Eclipse 项目中是否有 .servlet API?This can happen when you've compiled/built your webapp/WAR against a JSP/Servlet version which isn't supported by the container which is running in production. For example, you're developing using Tomcat 7, but you're finally deploying it to Tomcat 6. Ensure that the target runtime servletcontainer is of the same JSP/Servlet version as the servletcontainer which you're developing against in Eclipse.
Rightclick project and check in properties the Project Facets if the Dynamic Web Module version matches the maximum supported Servlet API version as your target runtime. E.g. Tomcat 6.0 supports only Servlet 2.5. Also you should prefer developing against exactly the same servletcontainer make/version as is running in production. This can then be set in Targeted Runtimes section of the project's properties.
You should also ensure that you don't have any container-specific libraries in the
/WEB-INF/lib
of your webapp. See also How do I import the javax.servlet API in my Eclipse project?
