## Overview

Online-Product-Store is a Java servlet/JSP web application for user accounts, product browsing, shopping carts, purchases, and administrator product management. The likely user journey is to browse the catalog, add products to a session cart, select an item to buy, and proceed through purchase confirmation; the tree also indicates registration, login, profile, and password-recovery flows. Admin screens support catalog maintenance. The README provides no architectural detail, and only a subset of source was sampled, so links for unsampled handlers and integrations are limited to clear names and module boundaries.
