Struts2 Error when Deploying: Unable to load bean: type: class:com.opensymphony.xwork2.ObjectFactory

Question

I\'m creating a basic Struts2, Maven webApp and getting this error when I deploy to Tomcat 6 or Jetty. Has anyone seen this?

Your problem is actually quite clear if you read the stack trace:

Caused by: Bean type class com.opensymphony.xwork2.ObjectFactory with the 
name xwork has already been loaded by bean -
jar:file:/C:/workspaces/ulearn/ulearn/target/work/webapp/WEB-INF/lib/struts2-core-2.0.11.2.jar!/struts-default.xml:30:72
 - bean -
jar:file:/C:/workspaces/ulearn/ulearn/target/work/webapp/WEB-INF/lib/struts2-core-2.1.8.1.jar!/struts-default.xml:29:72

You have a copy of struts2-core-2.0.11.2.jar and a copy of struts2-core-2.1.8.1.jar in your WEB-INF/lib directories. I think you should only have one of them. Do some cleanup (running a mvn clean might be enough).

PS: I have no idea why you also have stuff coming from C:/workspace/test as show be the first line:

jar:file:/C:/workspaces/test/test/target/work/webapp/WEB-INF/lib/struts2-core-2.1.8.1.jar!/struts-default.xml:29:72

There is definitely something weird and messy with your classpath. I don't have any explanation beyond the one I gave above though.
