NoSuchMethodError: ConfigurationManager.addConfigurationProvider while deploying Struts 2 application on Apache Tomcat 8

Question

The application runs fine on the local machine.

On the server I have JDK-1.7 and Tomcat8. It is giving me the below error in localhost logs. The jar exists in the lib directory of the application.

Answer 1

The jar exists in the lib directory of the application

Which Jar ? Because I guess you're referring to the struts2-core-2.3.24.1.jar , that contains the StrutsPrepareAndExecuteFilter you're using, but you also need the xwork-core-2.3.24.1.jar (or whatever your version is), that contains the other methods the filter refers to

Answer 2

似乎 jar 版本不匹配，因为它能够在该 jar 中找到类文件，但不能在类 ConfigurationManager 中找到具有以下签名的方法

com.opensymphony.xwork2.config.ConfigurationManager.addConfigurationProvider (Lcom/opensymphony/xwork2/config/ConfigurationProvider;)

Answer 3

com.opensymphony.xwork2.config.ConfigurationManager is in the xwork*.jar and it doesn't have a method addConfigurationProvider() . If your app

runs fine on local machine

then you have another jar with the same name file somewhere on the server lib. But this file has a different version. Make sure you have the same version for struts2-core*.jar and xwork-core*.jar .

This is the link where you can download all required libraries.

Put necessary libraries to the WEB-INF/lib and clean up the server classpath.

Answer 4

所以当我切换到 tomcat7 而不是 tomcat8 时，应用程序运行良好。
