解决方案

java.lang.VerifyError:(类:org/apache/jasper/runtime/JspApplicationContextImpl，方法:createELResolver签名:()Ljavax/el/ELResolver;)函数的参数不兼容

当您针对生产环境中运行的容器不支持的JSP/Servlet版本编译/构建了webapp/WAR时，可能会发生这种情况.例如，您正在使用Tomcat 7进行开发，但最终将其部署到Tomcat6.请确保目标运行时servletcontainer与您在Eclipse中开发的servletcontainer具有相同的JSP/Servlet版本. >

右键单击项目，然后检查 Project Facets 的属性，如果 Dynamic Web Module 版本与目标运行时所支持的最大Servlet API版本匹配.例如. Tomcat 6.0仅支持Servlet 2.5.同样，您应该更喜欢针对与生产环境中运行的Servletcontainer完全相同的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Webapp的/WEB-INF/lib中没有任何特定于容器的库.另请参见如何导入javax我的Eclipse项目中的.servlet API?

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

解决方案

java.lang.VerifyError: (class: org/apache/jasper/runtime/JspApplicationContextImpl, method: createELResolver signature: ()Ljavax/el/ELResolver;) Incompatible argument to function

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?
