I'm looking for some good discussion sites devoted to all manner of issues concerned in the creation and maintenance of ecommerce sites (mine would be with Java.)
My interest is in figuring out things like:
+ availability of open source EJB beans, e.g., 'shopping cart', that I can just plug into my app
+ recommended approaches to integrating shipping, e.g., UPS business services
+ recommended approaches to integrating payment, e.g., credit cards and PayPal
It doesn't see to me that JavaRanch is concerned with things like the forgoing, as they are basically domain-oriented.
