Answer 1

The error

java.lang.UnsupportedClassVersionError: org/apache/struts2/dispatcher/filter/StrutsPrepareAndExecuteFilter : Unsupported major.minor version 51.0

Struts2 is compiled with java7, but your server is using jdk1.6. Here what you have to learn how to build Struts2 with java 8.

Use maven to build struts2 from sources. In the maven compiler plugin use the target version 1.8.
