Here's how to fix it:

Error message prompt cannot load:struts.xml file.

View the DOCTYPE definition for the Struts.xml file The discovery version is inconsistent with Struts2-core-2.1.8.1.jar and is modified as follows:
Modify the Declarations section in Struts.xml to the file declaration Struts-default.xml in the jar package Struts2-core-2.1.8.1.jar for the project.
