Dein problem wurde bereits in der 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
```
Es scheint, dass Sie mehrere Kopien von struts2-core-*.jar in Ihrem WEB-INF/lib - Verzeichnis. Ich denke, Sie sollten nur einer von Ihnen. Tun Sie etwas Aufräumen. Auch zu sehen, wenn Ihr .classpath keine doppelten Einträge.

Völlig richtig, dupliziert Gläser verursacht mir das gleiche Problem!, danke!

Dies ist ein jar Problem. Sie müssen downloaden Sie die neuesten struts-jars.

Versuchen Sie die folgenden jar-Bibliotheken:
- common-chain-12.jar
- common-fileupload-1.3.1.jar
- commons-io-2.2.jar
- commons-logging-api-1.1.jar
Alle gängigen Gläser (freemarker.jar, javaassist.jar, ognl.jar, xwork-core.jar, struts2-core.jar) sollte die neueste version haben.

Achten Sie insbesondere darauf, die xwork und struts2-core-Gläser haben die gleiche version. Diese jar ' s sind nicht mehr optional nach Java 8.

Den Fehler ist einfach :

Klasse com.opensymphony.xwork2.ObjectFactory mit dem Namen xwork hat
bereits geladen bean .

Haben Sie Hinzugefügt struts2-core-X.X.X.X.jar zu deiner server-Klasse Weg ? Zusammen mit dem Projekt build path.

Wenn ja, dann entfernen. wird es funktionieren.
