> Hi all,

> I have a web app made using Struts 2 version 2.1.8, and its Convention an=
d REST plugins. I needed to update it to the latest version (2.3.24) but on=
e feature I used to have stopped working. I tracked the versions after 2.1.=
8, and found out that it was after version 2.3.7 that the problem started t=
o happen. I have created a simple app called =E2=80=9Cupgradetest" to isola=
te the problem. Here is the error scenario:
>
> I have an Action called HomeController, in which I have a method index() =
that is marked with the @Action(=E2=80=9C/=E2=80=9C) annotation, so that th=
e root url of the app maps to this method, like below:

> Normally, by visiting the root url of my app (=E2=80=9C/=E2=80=9C) in Str=
uts2 2.1.8, the index() method was called, and it then took the user to the=
 desired result. After the upgrade to 2.3.7, the web app is returning a 404=
 error.  I have investigated the source code and found out that the RestAct=
ionMapper of Struts Rest Plugin is returning null in the getMapping method =
(in the last line of code), something it did not in version 2.1.8. I believ=
e this change was done for some reason so I was wondering:
>
> Is there a way to map the root url (=E2=80=9C/=E2=80=9C) to a specific ac=
tion of mine without having to do a redirect or something like that (becaus=
e of a SEO requirement I have)? Also, am I doing it the wrong way?
