Java EE based e-commerce solution
===

#Hello everyone #

This is my first post in SOF. I enjoy tips & tricks which is provided by members of this community.

I am a newbie Java EE developer. I got my first app to build: a java ee based e-commerce.
I started doing uml modeling but i feel that i am wasting time, because there are ready solutions on the market.
When i did some searching i found some examples, as the Shoppizer, Broadleaf.. but these products are based on external frameworks as Struts or Spring, which i dislike ;(
I am searching some advices, ecommerce uml models, tips or even a roadmap to go on to build my ecommerce on pure java ee. Or if anyone knows a pure java ee solution. All suggestions are welcome :))
