HTTP Status 500 - No action instance for path /adduser could be created in struts

Question

I have a JSP page in which there is a hyperlink to add a user.

<html:link action="openadduser.do"> Add New User < /html:link>

My struts-config file contains

<action-mappings>
        <action path="/login" name="LoginForm" validate="true" input="/index.jsp"
            type="useraction.LoginAction">
            <forward name="successadmin" path="/home.jsp" />
            <forward name="failure" path="/index.jsp" />
            <forward name="successuser" path="/welcome.jsp" />
        </action>

    <action path="/adduser" name="AdduserForm" validate="true" input="/adduser.jsp"
            type="useraction.AdduserActions">
            <forward name="success" path="/userconfirm.jsp" />
        </action>

       <action path="/openadduser" name="AdduserForm" validate="true" type="useraction.AdduserAction"
            input="/adduser.jsp">
            <forward name="success" path="/userconfirm.jsp" />
        </action>
</action-mappings>

And my adduser.jsp contains code

<html:form action="/adduser">
     < h1 align="center">  ADD NEW USER < /h1>
     < bean:message key="label.fname"/> <br/>
     <html:text property="fname"></html:text><br/>
     <html:errors property="fname" /><br/>
     </html:select>
    <html:submit/>
</html:form></body></html>

AdduserAction.java contains

public ActionForward execute(ActionMapping mapping, ActionForm form,
            HttpServletRequest request, HttpServletResponse response)
            throws Exception 
    {
        AdduserForm adduserForm = (AdduserForm) form;

        fname = adduserForm.getFname().toString();
        System.out.println(fname);
        return mapping.findForward("success");

    }

I am using a Tomcat server. After I click on the submit button to add a user, it gives the following error. HTTP Status 500 - No action instance for path /adduser could be created in struts.

I think there is a problem in the struts-config file. What can I do to remove this error? Thank you for the help.

You cannot extend the 'Action' class in your LoginAction. That's the only reason for no action instance for path. You must extend the Action class, don't forget...

I don't understand. This seems contradictory. – Nicolas Barbulesco Nov 14 '13 at 16:39

I think appending .do in your jsp should solve the problem

<html:form action="adduser.do">

@vicky try removing the "/" from jsp, that is try action="adduser.do" – Zohaib Dec 20 '11 at 04:32
It is still giving same error. Actually in struts-config file i have a separate action for submit button on add user and separate action for the hyperlink to open add user jsp . Is there is some conflict in this? – vikiiii Dec 20 '11 at 04:36
SEVERE: No action instance for path /adduser could be created java.lang.ClassCastException: useraction.AdduserActions cannot be cast to org.apache.struts.action.Action – vikiiii Dec 20 '11 at 04:38
The action class is not in the classpath or you must have miss spelt the action class!!! – Pradeep Dec 20 '11 at 04:44
Pardeep is right, this might be the reason. By the way is it AdduserAction or AdduserActions because you are using oth, or are they really different classes. – Zohaib Dec 20 '11 at 04:47
They are different classes. But content is same. Actually i was just trying if it could work. But it is not working.Both have same content. – vikiiii Dec 20 '11 at 04:48
I have added AdduserAction class in my question. – vikiiii Dec 20 '11 at 04:51
does AdduserAction extends Action class? – Zohaib Dec 20 '11 at 04:53
Yes,It is extending Action class. – vikiiii Dec 20 '11 at 04:57
@Zohaib actually when you asked whether AdduserAction extends Action class? Then only i extend it. But it again was showing error. But when i put "/" in adduser.jsp for "/adduser.do" . It started working. Thank you so much. – vikiiii Dec 20 '11 at 05:00
Why is this the accepted answer when it's followed by a discussion about it not working? – Jobbo Dec 06 '18 at 09:25

@vicky : in action tag change validate="true" to validate="false"

It worked for me...
