In this tutorial, the cascading style sheets CSS are modified to change the color and layout of the storefront.
The new style is then made available as a display option for a starter store. In order to use Struts 2 uploads, ensure that you have enabled the capability. A data bean is a Java bean that is used within a JSP page to provide dynamic content. A data bean normally provides a simple representation of an HCL Commerce entity bean. The data bean encapsulates properties that can be retrieved from or set within the entity bean. As such, the data bean simplifies the task of incorporating dynamic data into JSP pages.
At the same time, business logic has been moving into data beans. The combination of these steps allows for less Java code in a JSP page. The purpose of double-click handling in HCL Commerce is to prevent processing the same request twice to ensure data integrity within the system.
When processing certain URL requests, such as OrderItemAdd, the double-click feature of HCL Commerce will identify whether the request from the online shopper is currently being processed and blocks the current request if that is the case. The Controller layer is the conductor of operations for a request. It controls the transaction scope and manages the session related information for the request. The controller first dispatches to a command and then calls the appropriate view processing logic to render the response.
The business logic layer is the business components that provide OAGIS services to return data or start business processes. The business logic provides data required by the presentation layer.
The business logic layer exists because more than just fetching and updating data is required by an application; there is also additional business logic independent of the presentation layer.
The interaction between the business objects and persistence layer is isolated in an object called the Business Object Mediator. Business object document BOD commands interact with the Business Object Mediator to handle the interaction with the logical objects and how they are persisted. A business model, a representation of the business processes used throughout the site, provides a sample commerce solution which includes an organization structure, default user roles and access control policies, one or more starter stores, administration tools, and business processes that demonstrate best practices.
A business model can be customized to support business requirements and scenarios. HCL Commerce provides sample business models that show some common commerce solutions. These business models are created by setting up an organization hierarchy structure, access control policies, stores, and contracts that help satisfy the necessary business requirements.
Before starting to develop your site with HCL Commerce , you need to determine the business model supported by HCL Commerce that best represents the purpose of your site. Usually sites created with HCL Commerce will be implemented based on of one of these business models. Store data is the information that is loaded into the Transaction server database, which allows your store to function. These entries are presentation configuration that is, struts actions and forwards that must be deployed.
URL registry entries are shown in the diagram to illustrate the entire store data information model. To operate properly, a store must have the data in place to support all customer activities. For example, in order for a customer to make a purchase, your store must contain a catalog of goods for sale catalog data , the data associated with processing orders tax and shipping data , and the inventory to fulfill the request inventory and fulfillment data.
You can extend the HCL Commerce product to fit your business needs. This topic describes the prerequisite skills and required knowledge that you need to customize business logic. After you have the required knowledge, use HCL Commerce Developer to take tutorials that guide you step-by-step through various customization scenarios.
The Run Engine command framework provides predefined commands, that you can use to change environment parameters or container configurations. This framework is built into the HCL provided Docker images.
