Struts 2 Configuration Files Path

If you are a first time developer who start working on the Struts 2 application, you would have got the below exception and no clue how to fix this problem. This error is thrown because your struts 2 application not able to read your configuration file struts.xml. In any other frameworks we keep the configuration files under the WEB-INF folder which will be taken automatically.

But, in struts 2, by default the configuration file struts.xml is looked at WEB-INF/classes folder. It resolve this problem, copy the struts.xml file directly under the source folder like below screenshot. It is always should be inside the classpath of the project.
