There is no Action mapped for namespace [/] and action name error

Question

This is the error messages:

WARNING: No configuration found for the specified action: 'welcome' in namespace: ''. Form action defaulting to 'action' attribute's literal value.

I have tried to put the struts under WEB-INF/classes already but it still doesn't work. I haven been stuck here a couple days now, please help.

struts.xml

<?xml version="1.0" encoding="UTF-8"?>

    <action name="welcome" class="com.struts3.LoginAction" method="execute">
        <result name="SUCCESS">welcome.jsp</result>

error message error

The error message in the title and the one in the question are different. So which one do you get? There is no such thing yet `DTD Struts Configuration 3.0`. Show your jsp. — Aleksandr M, Dec 10 '15 at 10:23
yeah, it should be `DTD Struts Configuration 2.5`. Also I posted my jsp — Andy, Dec 10 '15 at 15:10
You're not using S2 `2.5`. Don't use dtd for `2.5`. It is just a warning. Is something not working? — Aleksandr M, Dec 10 '15 at 19:48
when I sumbit the form, it wont show up welcome page, it displays http 404 error — Andy, Dec 11 '15 at 03:21
I added two images display the error after I click submit the form. — Andy, Dec 11 '15 at 14:10

The struts.xml configuration file must be on the root of the classpath, then on WEB-INF/classes, not in subpackages.

It should be put somewhere under src, and be copied to WEB-INF/classes at build-time by your favorite build-tool (Eclipse, Ant, Maven, ecc).

so I put my **struts.xml** under `src` but it didn't cope the **struts.xml** to the `WEB-INF/classes` and I still get the same error. – Andy Dec 10 '15 at 14:56
Your build tool MUST copy the struts.xml from its original location (`src/whatever`, for example `src/main/resources`) to `WEB-INF/classes`. If it doesn't, this is another problem that you should fix before coming back to this one. When it will copy the struts.xml in `WEB-INF/classes`, it should work. – Andrea Ligios Dec 10 '15 at 15:33
