> I have a "index.jsp" and invoke an action using "s:action" tag, then render

> Snippet from my JSP:
> {quote}{{<s:action name="myAction" var="myActionResult">}}
> {{ ...}}
> {{ <s:iterator value="#myActionResult.items">}}
> {{ </s:iterator><table><tbody>}}

> I was told (question on the [mailing
> list|https://lists.apache.org/thread/f4l1t4vtmvobl4l9jycfw5sj2dh7xyx1]) that
> direct access to a jsp is not supported. This issue is about creating a
> helpful error message instead of printing a (meaningless) exception on the
> console.
>
> Attached are two sample apps, one for Struts 2 (runs on a WildFly 26 server)
> and Struts 7.0 M9 (WildFly 33 server). Reproduce the error by calling
> "http://localhost:8080/Struts7Sample/index.jsp";. It works when invoking
> "http://localhost:8080/Struts7Sample/index.action";.
> The war files contain the sources for the actions, and also all necessary
> Struts jars. You can import it to Eclipse by using the type "Import" => "Web"
> => "WAR file"
