Solution 1

Your problem has been mentioned in stack trace:

Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the name xwork has
 already been loaded by bean - jar:file:/F:/m/.metadata/.me_tcat/webapps/project/WEB-INF
/lib/struts2-core-2.1.8.1.jar!/struts-default.xml:29:72 - bean - jar:file:/F:/m/.metadata
/.me_tcat/webapps/project/WEB-INF/lib/struts2-core-2.2.3.jar!/struts-default.xml:29:72

It seems that you have multiple copies of struts2-core-*.jar in your WEB-INF/lib directory. I think you should only have one of them. Do some cleanup. Also see if your .classpath does not have duplicate entries.

Solution 2

This is a jar issue. You need to download all the latest struts jars.

Try the following jar libraries:

  • common-chain-12.jar
  • common-fileupload-1.3.1.jar
  • commons-io-2.2.jar
  • commons-logging-api-1.1.jar

All common jars (freemarker.jar, javaassist.jar, ognl.jar, xwork-core.jar, struts2-core.jar) should have the latest version.

Especially ensure the xwork and struts2 core jars have the same version. These jar's are no longer optional after Java 8.
