Help!_no Action mapped for action name HelloWorld
Hi all,
I am tring to integrate Struts 2 HelloWorld into my project, but there came
the error message:
"There is no Action mapped for action name HelloWorld. - [unknown
location]", I think it is configuration problem, but do not know how to fix
it.
My project war structure like these:
/myproject/
- index.html
-/hello/HelloWorld.jsp
-/WEB-INF/
- struts.xml
- web.xml
-/WEB-INF/lib/web/HelloWorld.class
Here is my struts configure file struts.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts
Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.enable.DynamicMethodInvocation" value="false" />
<constant name="struts.devMode" value="true" />
<package name="hello" namespace="/hello" extends="struts-default">
<!-- Add actions here -->
<action name="HelloWorld" class="web.HelloWorld">
<result>/hello/HelloWorld.jsp</result>
</action>
</package>
</struts>
And here is my web.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<web-app id="GDI" version="2.4" xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
<display-name>myproject</display-name>
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
In the end, I test it in Tomcat using
http://localhost:8080/myproject/hello/HelloWorld.action,
"There is no Action mapped for action name HelloWorld. - [unknown location]
com.opensymphony.xwork2.DefaultActionProxy.prepare(DefaultActionProxy.java:186)
org.apache.struts2.impl.StrutsActionProxyFactory.createActionProxy(StrutsActionProxyFactory.java:41)
org.apache.struts2.dispatcher.Dispatcher.serviceAction(Dispatcher.java:494)
org.apache.struts2.dispatcher.FilterDispatcher.doFilter(FilterDispatcher.java:419)
"
Please help!!!
Thanks.
