Your jars are completely messed up:

1. Always preserve versions consistency (eg. not core 2.1.8.1 and plugins 2.2.3)
2. Always pick up the latest version (eg. 2.3.x or, if you can break retrocompatibility, 2.5.x)
3. Always include only the Struts2 plugins you know and use, only the needed ones. Remove all the others.
4. Always avoid including two versions of the same libraries, eg. poi 3.7 and poi 3.8. Is this a joke ?
5. The first versions of Tomcat 8.0 had known problems with Struts2, you should upgrade to the latest (eg. 8.0.39) or, even better, to 8.5.
