Struts result JSP 404 - spring

Question

I'm new to Struts2, just finished a no action mapped issue, my action new will be execute, but while it return to JSP, there is always 404. Tried to set namespace and result like following, but still don't get it work.
struts.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
<constant name="struts.devMode" value="true" />
<constant name="struts.convention.result.path" value="/WebContent/jsp/" />
<package name="default" extends="json-default">
<action name="testAction" class="tw.com.rrstudio.java.test.TestAction" method="execute">
<result name="login">index.jsp</result>
<result name="success">TestAction.jsp</result>
</action>
</package>
</struts>
Also tried remove convention result path and set result as this
<package name="default" extends="json-default">
<action name="testAction" class="tw.com.rrstudio.java.test.TestAction" method="execute">
<result name="login">/jsp/index.jsp</result>
<result name="success">/jsp/TestAction.jsp</result>
</action>
</package>
But still gives 404.

my action java code
package tw.com.rrstudio.java.test;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.interceptor.ServletRequestAware;
import com.opensymphony.xwork2.ActionSupport;
public class TestAction extends ActionSupport implements ServletRequestAware
{
private static final long serialVersionUID=1L;
public HttpServletRequest request;
private String name="";
public String execute() throws Exception
{
System.out.println("Debug: name="+name);
System.out.println("Debug: path="+request.getContextPath());
System.out.println("Debug: path="+request.getServletContext().getRealPath("/"));
if(name!=null && !"".equals(name))
{return "success";}
else
{return "login";}
}
#Override
public void setServletRequest(HttpServletRequest request)
{this.request=request;}
public String getName()
{return name;}
public void setName(String name)
{this.name=name;}
}
While I call my action, it do printed debug message like this,
http://127.0.0.1:8080/Struts2Test/testAction.action
Debug: name=
Debug: path=/Struts2Test
Debug: path=D:\eclipse\workspace2.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Struts2Test\
http://127.0.0.1:8080/Struts2Test/testAction.action?name=XYZ
Debug: name=XYZ
Debug: path=/Struts2Test
Debug: path=D:\eclipse\workspace2.metadata.plugins\org.eclipse.wst.server.core\tmp0\wtpwebapps\Struts2Test\
but always give me a 404 page, and no any message.
