I have been thinking a little more about the BreadCrumbInterceptor. It
may be a blunt instrument but I was thinking it would be a fair
assumption to only include actions invoked via the GET method in the
bookmarks trail. This could be achieved in the interceptor with code a
bit like:
ActionContext context = invocation.getInvocationContext ();
HttpServletRequest request = (HttpServletRequest)context.get(HTTP_REQUEST);
if ("GET".equals(request.getMethod()){
// Do the magic stuff
}
I also thought that breadcrumbs of this nature would be really useful in
an application that stores the most recent searches (imagine a S2 app
using Lucene). In this scenario it would be good to additionally
include the querystring in the breadcrumb URL.
The only problem with these suggestions is that it makes it a far less
simple example (and I don't plan on paying for my feature requests - do
I qualify for the 3 for $250 yet?).

The motive website article is almost comprehensive, but they miss 2
points about breadcrumb history menu:
firstly it's not redundant just because of the browser's history
functionality - when you go back in the browser and then choose a new
link, you lose your ability to go forward in the browser history
again. A breadcrumb menu keeps your history even if you retrace your
steps.
secondly for that reason, there is no need to try to work out whether
a page is in the history already or not. Just let it appear twice or 3
times or however many times.
But their point that breadcrumb history menus only having use in
certain situations is very true. I always wish that javadocs had it
built in.

Good stuff. Here is some feedback for you, free of charge. :)
There is a slight issue with www.strutsschool.com (demo site for the
breadcrumb plugin?). I think flipCoin should probably appear in your
excludeMethods as accessing flipCoin through the breadcrumb link
throws an exception. (the flipCoin breadcrumb is created by clicking
on submit on the samples.action page).
Also, I think you need to make it clear that this provides
"breadcrumb navigation as transcript/history" rather than the
"Homeward Path" style of breadcrumbs that is more prevalent.
(Breadcrumbs is a most ambiguous term!).
<http://www.motive.co.nz/glossary/breadcrumb.php>
<http://developer.yahoo.com/ypatterns/pattern.php?pattern=breadcrumbs>
My personal preference would be to display breadcrumbs in an
unordered list with appropriate CSS styling. e.g.:
<http://www.alistapart.com/articles/taminglists/>
I was also thinking that a homeward path breadcrumb navigation
implementation would be a good demonstrator for the S2 XSLTResult type.

Greetings --
I finished the S2 breadcrumb plug-in and you are welcome to it and the
source code at www.strutsschool.com. I plan to cover the plug-in
process in
a chapter of the Struts 2 in Action
<http://www.manning.com/dbrown/> book
which is soon to be released. Until then, a few folks have asked if
they
could get it sooner. Once you download the plug-in, be sure to see the
README.txt file contained inside the jar. This explains how to add and
configure the plug-in to your liking and sample HTML code for
displaying the
crumbs on your site.
Please let me know of any issues that you encounter and I will accept
feature requests at $100.00 each or three for $250.00! :)
