I spent some time in the debugger and found out what 'really' changed was
the default action extensions (struts.action.extension) changed from just
'action' to 'action' plus "" (no extension). This was causing my "/status"
request with no extension to be treated as an action.
The old (2.0.11) struts default.properties had:
struts.action.extension=action
The new (2.1.6) has:
struts.action.extension=action,,
If I explicitly set the extension back to just 'action' then It works like
it used to and the request goes thru to my servlet.
In my struts.xml I added: <constant name="struts.action.extension"
value="action" />
So I still have the question of what is the 'correct' filter mapping for the
struts filter?
I found the FilterDispatcher javadocs which says:
"IMPORTANT: this filter must be mapped to all requests. Unless you know
exactly what you are doing, always map to this URL pattern: /* "
I also see that FilterDispatcher has been deprecated, a note in the upgrade
guide would have been nice :). (I'm going to add what I've found to the
wiki so will include a note.)
