I can not even think why is that? And my other files are like below,
Action file
public class PcArcadeAction {
public String execute()
{
String success="success";
return success;
}
}

I am getting error in struts.xml and it says The public identifier must begin with either a single or double quote character
Here is my folder structure :

Answer 1

As the exception clearly states,
Caused by: java.lang.ClassNotFoundException: freemarker.cache.TemplateLoader
It is just a simple case of some missing jars ( freemarker in this case ).
If this is the first time you are making a struts application, I suggest you start with the blank struts war. It is a simple deployabe war file that contains all the basic jars and resources/files that are required to deploy and run a struts2 project successfully.
Here is the direct link to the war file.

Answer 2

You just have to check that did you added all the required .jar files. these are below jar which you have to add:
Maintain following version of jars in you lib. I think you won't face any problem
antlr-2.7.6.jar
commons-beanutils-1.7.0.jar
commons-collections-3.2.jar
commons-digester.jar
commons-fileupload-1.2.2.jar
commons-io-2.4.jar
commons-lang-1.2.jar
commons-logging-1.1.jar
freemarker-2.3.16.jar
javassist-3.7.ga.jar
ognl-3.0.jar
struts2-core-2.2.3.jar
xwork-core-2.2.1.jar

Answer 3

Looks like freemarker jar is missing. This should rectify current issue.
If other dependent JARs are missing then you will some other exceptions after this.
