I've still not gotten my urlrewrite rules working, but I'm hoping to

and struts am I going to be able to get that working?
There's only one way to find out. ;-)
As I mentioned, I've never managed to get it working (even before the
staticFilter). I've attempted several times and failed each time (and
put it back on the TODO list). Next time it pops off my TODO list I'll
send an update with the results, but I suspect it just got more rather
than less complicated. Maybe not, as I can just exclude the urls to be
rewritten in the staticFilter specification.
(Quick test shows that it's now failing in the view layer maybe because
the struts filter never ran? :
java.lang.NullPointerException
org.apache.struts2.views.jsp.ComponentTagSupport.doStartTag(ComponentTagSupport.java:50)
org.apache.jsp.decorators.default_jsp._jspx_meth_s_url_0(default_jsp.java:379)
Actually, I think that might be an improvement over my last attempt,
because before I don't think I ever got the action to run at all, much
less completing and failing in the view layer. Maybe this means I have
the urlrewrite portion configured correctly, even though I've still
never gotten a rewritten page to work.) Leaving this on my TODO list
for now.
NEW SUBJECT BEGINS HERE:
OK--this was good--it got me to test the staticFilter and fix some
configuration issues (I was including /scripts/dojo/* instead of
/struts/dojo/*), but I still don't understand how the staticFilter is
supposed to work:
http://localhost:8080/myapp/struts/dojo/src/widget/templates/DatePicker.css
works, but
http://localhost:8080/myapp/struts/dojo/src/widget/templates/DatePicker.html
does not work, and I don't understand how it could. The stack trace
shows that it matched the right rules in staticFilter.doFilterInternal,
and that resulted in a call to forward to a dispatcher
(StaticFilter.java:92), but I don't understand why I should expect the
dispatcher to find a "static" page that only exists deep inside the
struts .jar? Do I need to extract part of the .jar someplace so that
this can work? Should I be using a different dispatcher somewhere?
Separately, I also don't understand why OncePerRequestFilter appears six
times in the stack trace? I'm guessing from the name that it should
only appear once...
