As suggested, I've made some improvements in the sample store. Now the catalog data is accessed by JDBC instead of a hardcoded table in memory. ( https://issues.apache.org/jira/browse/TUSCANY-1844)
After running the sample with the property currencyCode configured as 'EUR', in the store.composite, I got an float parse error in the getTotal method in the ShoppingCartImpl. Because of that, I've changed a little the way of get the price of each product. Suggestion?
