Dan,
Thanks. I've got unittests running now, but the WicketFilter doesn't
seem to be processing. All I get when I run the applicaiton shows a
jetty produced directory listing.
In the snippet you provided before I think that CustomFilter and
CustomeWicketFilter should be the same thing. Is that right?
In my previous approach, when I bound the WicketFilter I included some
parameters, like this:
filter("/*").through(WicketFilter.class,
createWicketFilterInitParams());
With this function
private Map<String, String> createWicketFilterInitParams() {
Map<String, String> wicketFilterParams = new HashMap<String, String>();
wicketFilterParams.put(WicketFilter.FILTER_MAPPING_PARAM, "/*");
wicketFilterParams.put("applicationClassName",
"com.hp.honeybadger.web.WicketApplication");
return wicketFilterParams;
}
I'm now trying to figure out how to make sure that the wicket filter
is called...
Daniel
