The action mapping of struts-config:
<action-mappings>
<action
path="/CheckAge"
type="coreservlets.CheckAgeAppAction"
name="CheckAgeAppForm"
scope="session"
validate="false"
input="/welcome.jsp">
<forward name="UnderAge" path="/UnderAge.jsp" />
</action>
<action path="/welcome" forward="/welcome.jsp"/>
</action-mappings>
form-bean of struts-config:
<form-bean
name="CheckAgeAppForm"
type="coreservlets.CheckAgeAppForm"/>
</form-beans>
The welcome.jsp file contents:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>
</head>
<body>
<div style="color:red">
<html:errors />
</div>
<html:form action="/CheckAge.do" >
User Name : <html:text name="CheckAgeAppForm" property="name" /> <br>
Password : <html:text name="CheckAgeAppForm" property="age" /> <br>
<html:submit value="Check Age" />
</html:form>
</body>
</html>
The web.xml portion :
<!-- Standard Action Servlet Mapping -->
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
The action form CheckAgeAppForm:
package coreservlets;
import org.apache.struts.action.*;
public class CheckAgeAppForm extends ActionForm {
private String name;
private String age;
public String getName(){
return (name);
}
public String getAge(){
return (age);
}
public void setName(String name){
this.name= name;
}
public void setAge(String age){
this.age = age;
}
}
the CheckAgeAppAction:
package coreservlets;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.*;
public class CheckAgeAppAction extends Action
{
public ActionForward execute(
ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception{
return mapping.findForward("UnderAge");
}
}
I would greatly appreciate any help with this its frying my brain, thanks in advance
UPDATE:included the Action, also action mapping updated

I finally solved this problem among other ones which followed. The jsp file uses the .do :
<html:form action="/AgeCheck.do" >
The action mapping has no .do :
<action
path="/AgeCheck"
type="coreservlets.CheckAgeAppAction"
name="AgeCheckForm"
>
<forward name="UnderAge" path="/UnderAge.jsp" />
</action>
Following is the Error I had
No action instance for path could be created
This was caused by the file structure of my project which meant that the java files were not being compiled, by default the java files were stored here:
I've Moved those exact Files with no changes to here :
And Hey presto everything works :-) Hopefully this will help someone in future, thanks everyone for help, I can't upvote yet unfortunately.

If your posted Struts config is that you have in you app, I see there one error, you haven't included forward tag inside your action mapping, you have closed your action before forward tag:
<action
path="/CheckAge"
type="coreservlets.CheckAgeAppAction"
name="CheckAgeAppForm"
scope="session"
validate="false"
input="/welcome.jsp">
<forward name="UnderAge" path="/UnderAge.jsp" />
</action>

There should be something like caused by below root cause inside your stacktrace, so please post it also.
But anyway, one thing looks suspicious to me. Your struts config has:
<action
path="/CheckAge"
type="coreservlets.CheckAgeAppAction"
...
but documentation for the type attribute says that:
Fully qualified Java class name of the Action subclass [org.apache.struts.action.Action] that will process requests for this action mapping. Not valid if either the "forward" or "include" attribute is specified. Exactly one of "forward", "include", or "type" must be specified.
But in the code you posted you don't have class coreservlets.CheckAgeAppAction - you only have a coreservlets.CheckAgeAppForm. Is this a mistake? Or did you just skip this for brevity?
EDIT: ok, a false trail - you skipped it only for the sake of brevity. Sorry, then I have no clue.
BTW: if I can give you some advice, don't touch Struts 1.x. If you have to work with it at your workplace, probably it would be better to quit this job. Struts 1.x is very weird and developer-unfriendly. Moreover, is also discontinued since 2008...
