Problem running a simple webapplication in struts

[Varun Nayudu]

Hi

I am having problem running a simple webapp in struts here is the full code with the error

URL:
http://localhost:8181/StrutsApp2/UserRegistrationAction.do

web.xml:

<web-app>
	<servlet>
		<servlet-name>action</servlet-name>
		<servlet-class>org.apache.struts.action.ActionServlet</servlet-class>
		<init-param>
			<param-name>config</param-name>
			<param-value>/WEB-INF/struts-config.xml</param-value>
		</init-param>
		<load-on-startup>2</load-on-startup>
	</servlet>
	<servlet-mapping>
		<servlet-name>action</servlet-name>
		<url-pattern>*.do</url-pattern>
	</servlet-mapping>
</web-app>

struts-config.xml:

<struts-config>
	
	<action-mapping>
		<action path="UserRegistrationAction" type="com.action.userRegistrationAction" >
			<forward name="success" path="/successfull.jsp"/>
		</action>
	</action-mapping>

</struts-config>

Action class

package com.action;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionMapping;
import org.apache.struts.action.ActionForward;

public class userRegistrationAction extends Action{
	public ActionForward execute(ActionMapping mapping, ActionForm form,
		HttpServletRequest request, HttpServletResponse response)throws Exception{
System.out.println("----------------------------------------------------------");
		return mapping.findForward("success");
	}
}

Error which i got

     <action-mapping>  

is it action-mapping or action-mappings ?

[Varun Nayudu]

Thanks man for your answer.

<struts-config>
	
	<action-mappings>
		<action path="UserRegistrationAction" type="com.action.userRegistrationAction" >
			<forward name="success" path="/successfull.jsp"/>
		</action>
	</action-mappings>

</struts-config>

Few silly mistakes i can see in struts config. Please check out some tutorial struts-config before any queries

Couple of things to note
Your action path and html form action should match.
Restart the server after the changes

Thanks for your reply I went through the documentation but still i cant find the error what is casing this, I changed the struts-config.xml

<struts-config>
	
	<action-mappings>
		<action path="UserRegistrationAction.do" type="com.action.userRegistrationAction" >
			<forward name="success" path="/successfull.jsp"/>
		</action>
	</action-mappings>

</struts-config>

Now please tell me what am i doing wrong ...

I'd start by fixing that; your application isn't starting up.

Thanks for your reply I went through the documentation but still i cant find the error what is casing this, I changed the struts-config.xml

<struts-config>
	
	<action-mappings>
		<action path="UserRegistrationAction.do" type="com.action.userRegistrationAction" >
			<forward name="success" path="/successfull.jsp"/>
		</action>
	</action-mappings>

</struts-config>

What is the change you did ? Is it a valid xml ? Does it have valid DOCTYPE DTD declaration at the start ?
check this struts-config.xml

Also, action path must start with "/". First make sure the server startups without errors.
