I am building my first struts2 app and am getting the error:
- HTTP Status 404 - /Struts2Beginner/Input.jsp
- type Status report - message /Struts2Beginner/Input.jsp description The requested resource is not available.
- Apache Tomcat/7.0.64
There are a lot of posts on this problem and I think I eliminated 2 of the common problems:
- I am using StrutsPrepareAndExecuteFilter (instead of FilterDispatcher)
- I have both commons-lang-2.4.jar and commons-lang3-3.2.jar in my WEB-INF/lib
I am following the tutorial http://www.codejava.net/frameworks/struts/struts2-beginner-tutorial-eclipse-tomcat-xml?showall=&limitstart=
WEB-INF lib
- commons-fileupload-1.2.2.jar
- commons-io-2.0.1.jar
- commons-lang-2.4.jar

I have spent several hours trying to debug this with no luck so far.
