Jsp 在eclipse中工作的Web应用提供了Verify EL error org.apache.catalina.core.StandardWrapperValve调用

一个在Tomcat7环境中的Eclipse中运行良好的标准webapp给出了这个错误。有什么想法吗

应用程序在eclipse中运行良好……但Tomcat7和应用程序中的大量错误都没有响应

当您针对生产环境中运行的容器不支持的JSP/Servlet版本编译/构建webapp/WAR时，可能会发生这种情况。例如，您正在使用Tomcat7进行开发，但最终将其部署到Tomcat6。确保目标运行时servletcontainer与您在Eclipse中开发的servletcontainer的JSP/Servlet版本相同

如果动态Web模块版本与作为目标运行时支持的最大Servlet API版本匹配，请右键单击project并检入项目方面的属性。例如，Tomcat 6.0只支持Servlet 2.5。此外，您应该更喜欢使用与生产中运行的servletcontainer make/version完全相同的servletcontainer进行开发。然后可以在项目属性的目标运行时部分中设置

您还应该确保您的webapp的

/WEB-INF/lib

中没有任何特定于容器的库。另见
