store example as a servlet?
I have just been through the "get started in 10 minutes" and I like the
store example; it's small and neat. I was thinking of adapting it and
redoing it as a servlet, just to compare. I realise this is a backward
step in a way of course - instead of the AJAX style, back to page
refreshes, and running the code on the server. Nonetheless it would be
interesting to compare. Before I start, has anyone done it already?

Makes a lot of sense to me.
Both implementation.web and implementation.servlet are interesting:
- implementation.web models the contracts around a webapp and helps
assemble a webapp with others in a bigger SCA assembly.
- implementation.servlet can model the assembly of the webapp itself.

Thanks for the encouragement, all. I'll let you know how I get on.
This probably off topic for this list, but the choice between
<implementation.web> and <implementation.servlet> is an interesting one.
The page Jean-Sebastien refers to says that <implementation.web> is the
current thinking, but <implementation.servlet> has its virtues too. It
rather depends on whether you want the detail of the individual servlets
exposed for configuration - would you want per servlet aspects like the
servlet init parameters exposed as SCA properties for example? If you did,
you might like something like
<implementation.servlet name="<warfilename>#<servletname>">
<property name="currency">EURO</property>
</implementation.servlet>
In this case you could present currency to the servlet as a servlet init
parameter.
This properly a topic for the place in OSOA where the SCA-JEE integration
is discussed, of course, and I raised it as an issue there recently,
though it has not been discussed yet.

That makes sense to me. You could define a new <implementation.servlet>
implementation type or try to implement the <implementation.web>
described at http://www.osoa.org/pages/viewpage.action?pageId=3980.
