Why we need struts.action.extension property

[Igor Vlasov]

Hello. I wrote a simple s2 application.

I described a filter in web.xml

<filter>
<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>
</filter>

<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.jspa</url-pattern>
<dispatcher>FORWARD</dispatcher>
<dispatcher>REQUEST</dispatcher>
</filter-mapping>

but i forgot a struts.properties file and "struts.action.extension=jspa"

AND my project does not WORK


My question: why we need to write "struts.action.extension=jspa" when we
already have filter-mapping binding struts2->*.jspa

[Gabriel Belingueres]

AFAIK, the Servlet API doesn't expose any standard way to know the
mapping associated to a filter. Maybe that's way.

So Struts 2 itself knows what extension is being used for actions.

Note that mapping the S2 filter to something other than "/*" will break a few things unless we work around it. I added a note to the web.xml documenation [1], but basically unless we do something to get the static content served (extracting the files, etc.) things will break.
