title: Java Opensource E-Commerce solution
body: <p>I believe there are a lot of similar questions even on stackoverflow. But most of them are dated 1-2 years ago. Sorry about same question again.</p>
  
  <p>Could you suggest easy to run and tweak java based opensource E-Commerce solution. Before i used Magento, but it was really hard to change code at start. I spend almost 2 week to realize how Magento works. Performance was not good enough too.</p>
  
  <p>Now i'm looking for simple java solution, which can be customized or rewritten easy.</p>
