There's no initial /org/apache/tapestry5/pages resources directory
because the (old fashioned) alternative was to place the .tml files in
the webapp (aka context) directory. That's where they appear in the
tutorial.
However that technique is no longer recommended and the .tml files
should be placed along side your java files. As to why they don't work
in the context dir ('cos they should still work there really)... I
don't know - I've never tried it! :)
The maven archetype (along with the tutorial) was written a wee while
ago now and needs updating - which is why the .tml files are in the
wrong place.
If you put your .tml files in src/main/java/... (as I saw in your
screenshot) then you're reliant on eclipse copying them over to
target/classes/... but if you put them in src/main/resources/... then
it's maven wot copies them over. And as you're using maven to launch
jetty, you're better off relying on maven to do the leg work.
But cool, I'm pleased you're now in a position to start playing around
with components and T5 in general.
T5 is an excellent piece of engineering but it is mentioned frequently
on this list that the documentation is a bit light. That maybe, but
what I find really goes in T5's favour is the quality of the code and
the way it's completely modular. Unlike other arbitrary frameworks
(e.g. in my opinion, Spring) T5 is really well written, avoids
inheritance where it can, and most answers can be found by a quick
peek in the code.
Anyhow, have fun,
Steve.
