Hi Martin,
I see. I guess the concept of a "framework as an example" wasn't
immediately clear to me. Now I added a link to Yafra to the examples
page. Thanks a lot for your work!

Hi Andrus,
agree with your point, wrong location and it is easy to find it in
google. I still think it would be worth adding a link to http://yafra.sourceforge.net/
with a short description like "Using Cayenne within different java
technologies - a jump start".
The whole framework is based on Apache Cayenne. My driving point was
building different applications with a database as central back end.
Apache Cayenne was the ORM of choice. Instead of building a concrete
application to share with others, the idea came up to share all the
findings and the chosen approaches as a sort of a framework. The
framework shows how I embedded Apache Cayenne into Apache Wicket or
in simple console/batch programs or with a fat client written in
Eclipse RCP using EJB's (not using JPA) to access the Cayenne layer.
I will put some more effort into the trac sourceforge.net page to
give a better understanding how yafra shall be used.
Hope it helps,
Cheers,
Martin

Hi Martin,
May I suggest to add the Apache Cayenne examples below the success
stories on the main page or within the success stories. The examples
are quite hard to find (it's referenced on the cwiki index page)
and I
could find it only through google for apache cayenne examples.
I don't think examples belong on success stories page, as the
purpose of
the later is quite different - to highlight the use of Cayenne on
some
real-life projects. But answering your general point... The problem
with
the examples on cwiki, namely this link -
https://cwiki.apache.org/CAY/cayenne-examples.html , is that all of
those are old, unmaintained (as a matter of fact I just removed/
changed
some links that no longer work), and many are likely obsolete.
This is a #1 link shown to me by Google when searching for "cayenne
examples", so it is not hard to find per se, but the question is
whether
we want to endorse our old set of examples. I'd say them staying a
step
away from the main site is actually good in current situation :-)
If possible, somebody could add the link to my project as a further
example of using cayenne within different technology setups. A
link to
http://yafra.sourceforge.net/ would be excellent. It is yet another
framework, but not in fact to be reused as such, more to get / take
what you need to have a better learning curve.
I used cayenne with the DTO pattern within EJB3 setup serving an
Eclipse RCP EJB3 fat client (using Apache OpenEJB). As well a small
example using Apache Wicket with Cayenne. Working on a Google Web
Toolkit example and would like to move on to Eclipse Riena using
distributed OSGi (they use Hessian as well, seems to be an
interesting
example). With the yafra framework I did already a ROP example, but
not yet published. All sources are under SVN as Eclipse projects. I
use Trac to document.
Could you provide links to the parts of Yafra that can be used as
standalone Cayenne examples (does this request even make sense in the
context of Yafra? Not sure how it is organized) Or maybe
alternatively
you can provide us with a small writeup, explaining those parts
that we
can put on the wiki with links back to the appropriate pieces of
Yafra?
Cheers,
Andrus
