Subject Re: Web site link to example and a proposal for a new example link

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 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 page to give a 
better understanding how yafra shall be used.

Hope it helps,
