Unable to load configuration. Check whether the jar package is complete!
Besides
Commons-logging-1.0.4.jar
Freemarker-2.3.12.jar
Ognl-2.6.11.jar
Struts2-core-2.1.8.jar
Xwork-2.1.1.jar

These five core lib files must be copied,
Load the following two lib
Commons-fileupload-1.2.1.jar

Commons-io-1.3.2.jar

In addition, pay attention to the problem with the original code!
Take a closer look at your error message
Unable to load configuration. -action-file:/D:/Apache % 20 Software % 20 Foundation/Tomcat % 206.0/webapps/structs2/WEB-INF/classes/struts. xml: 23: 79
It cannot load the struts. xml configuration here. You should carefully check the code of that file!

 

In my own example, the cause of the error is:

The names of the two packages are the same. The name attribute in the package is equivalent to the id and cannot be duplicated. change one of the two packages to another value.
