Struts2 running exception

I am using myeclipse blue8.6, new project-, right-click Project-, myeclipse-, add struts capabilities, and add them as the default options.

No problem.

Add an action and deploy and run the project.

An exception occurs after the result is added:

Solution:

Find the package node in struts. xml:

<Package name = "com. Action">

Add the following attributes

Extends = "struts-Default"

Last XML:

<? XML version = "1.0" encoding = "UTF-8"?> <Br/> <! Doctype struts public "-// Apache Software Foundation // DTD struts configuration 2.1 // en" "http://struts.apache.org/dtds/struts-2.1.dtd"> <br/> <struts> <br/> <package name =" com. action "extends =" struts-Default "> <br/> <action name =" action "class =" com. action. action1 "> <br/> <result name =" success ">/Suc. JSP </result> <br/> <result name = "error">/err. JSP </result> <br/> </Action> </package> </struts> <br/>
