Struts2 tutorial doesn't work

问题

I'm learning struts2. And I try my hello world projects according to the tutorial Then I run the code in eclipse. But it doesn't work. The Console shows a lot of error. The first is as below:

 com.opensymphony.xwork2.util.logging.commons.CommonsLogger error
SEVERE: Dispatcher initialization failed
Unable to load configuration. - bean - jar:file:/C:/Users/Administrator/Eclipse/workspace_2/.metadata/.plugins/org.eclipse.wst.server.core/tmp0/wtpwebapps/MyStruts2/WEB-INF/lib/struts2-gxp-plugin-2.3.8.jar!/struts-plugin.xml:8:162

And the pages shows : HTTP Status 404 - /MyStruts2/index.jsp type Status report

message /MyStruts2/index.jsp

description The requested resource is not available.

What's wrong with it. Need I configure more?

回答1:

First, remove all unused S2 plugins If you're following a basic tutorial, you are almost certainly not using GXP.

S2 plugins:

May alter S2 functionality in fundamental ways, and
Have their own dependencies that will cause failures if their dependencies are not met.

Second, ensure you are deploying all required libraries. Maven (or the equivalent) was created to manage those dependencies, but for an absolute bare-bones app it's not strictly necessary.
