For those of you still having troubles resolving the above error. This is what i did that worked for me. Within the jsp page that is rendering the form, on the form tag, i just included the namespace of the package that the referred form action name is located, for example:

struts.xml ( this is just a fraction of my struts.xml config )

<package name="user" namespace="/user" extends="struts-default">
    <action name="update" class="actionbean.UserProfileUpdate">
        <result name="error">pages/error.jsp</result>       
        <result name="success" type="redirect">pages/profile.jsp</result>
    </action>
</package>

NOTE: the action name is update and it's within /user namespace.

profile.jsp --> This form generates above error

this code generates above error ( when i used it ), solely because i didn't include the namespace attribute

<form action="update" method="post">
    .....
    [ other codes ]
</form>

profile.jsp --> (this form runs as expected)

<form action="update" method="post" namespace="/user">
    .....
    [ other codes ]
</form>

please note: i'm not sure why this solution worked for me, reason is because i have several forms in my web app as at the time i'm providing this information, and i didn't have to do this in any other form except this update form.

vital information about my environment if needed

Product Version: NetBeans IDE 8.2 (Build 201705191307)

Updates: NetBeans IDE is updated to version NetBeans 8.2 Patch 2

Java: 1.8.0_161; Java HotSpot(TM) 64-Bit Server VM 25.161-b12

Strut: strut 2 core 2.3.15

Good luck with this.

Please copy your struts.xml file it will help to understand.what i can find from your log is that wither you have done wrong configuration in the xml file or you have defined an action in xml which is not yet defined
