t5: T5 friendly e commerce software?

Hi,
looking for an eCommerce software in Java, is there a 'Tapestry 5 friendly' one? to make it clear, I'm quite comfortable in Tapestry5 and like it very much, however, making an eCommerce software from scratch will be a big task, abandoning T5 for this coming project is something I don't like to happen, any suggestions to have T5 and an existing e Commerce software working together? Thanks,

A.C.
