struts 2.2.1 appends ".action" suffix to name

Question

My project changed version of struts from struts-2.1.8.1 to struts-2.2.1. We don't use suffix ".action" for naming, after migration it is appeared. For older version html code looks like:

<form id="Login" name="Login" action="/fm2/Login" method="post"> 

But new struts renders the same form:

<form id="Login" name="Login" action="/fm2/Login.action" method="post"

So difference that .action has been added. What's wrong with new release?

Answer 1

This is the default extension (and should be in 2.1.8.1 too).

You can change it in your struts.xml:

<constant name="struts.action.extension" value="whatever" />

Answer 2

This has not changed, AFAIK. Be sure to understand the difference between the "struts action" and the "action attribute of a HTML FORM" element

Typically, to render a FORM tag in Struts2 you'd use a (Struts2) form tag - its action attribute corresponds to the name of a Struts2 action, which corresponds to a url without the suffix (by default '.action', but you can change it)

So, the Struts2 tag

<s:form action="/fm2/Login">

would typically produce the HTML output

<form action="/fm2/Login.action">
