HCL Commerce foundation tag library
The HCL Commerce foundation JSTL tag library is a collection of custom tags that are provided to you to support the authoring of HCL Commerce JSP files. HCL Commerce stores use the JavaServer Pages Standard Tag Library (JSTL) to perform logic, instead of Java code. At the same time, business logic is moved into data beans. The combination of these steps allows for less Java code in a JSP page.
Deprecated feature: Tag: declareRenderContext
The wcf:declareRenderContext tag adds the client-side render context support to the current page. The ID passed to this tag is used to identify the render context. If this tag is already called for this request and ID, then no further call is made.

    When you deploy a container from an HCL provided image, an Entrypoint.sh helper script determines the configurations to use while starting up the container. Review the following information to learn about what the helper script does, and how you can customize the configurations.
  - HCL Commerce database schema
    The HCL Commerce database model was designed for data integrity and optimal performance. HCL Commerce provides several hundred tables that store HCL Commerce instance data. To maintain data integrity, and to ease maintenance referential integrity, constraints are widely used in the database model. Indexes are used carefully on tables to avoid over-indexing and to provide a good balance between data retrieval and data manipulation activities (insert and update). The business rules are implemented at the application level rather than by using database trigger. Triggers, however, are used to facilitate data staging and optimistic locking. A limited number of SQL-based database stored procedures are used for data intensive activities.
  - Payments subsystem
    In HCL Commerce, payment processing uses the Payments subsystem.
  - Dynamic caching
    In general, caching improves response time and reduces system load. Caching techniques are used to improve the performance of World Wide Web Internet applications. Most techniques cache static content (content that rarely changes) such as graphic and text files. However, many websites serve dynamic content, containing personalized information or data that changes more frequently. Caching dynamic content requires more sophisticated caching techniques, such as those provided by the WebSphere Application Server dynamic cache, a built-in service for caching and serving dynamic content.
  - HCL Commerce store pages properties
  - Cache-entry elements
    The root element of the cachespec.xml file, <cache>, contains <cache-entry> elements. The WebSphere dynamic cache service parses the cachespec.xml file during start-up, and extracts a set of configuration parameters from each <cache-entry> element.
  - Data Load utility configuration file schema
    The Data Load utility contains several configuration files. You can use the configuration file schema to understand and customize the data load configuration files.
  - HCL Commerce web services
    HCL Commerce provides many web services.
  - Utilities
    In HCL Commerce utilities are scripts that perform operations such as loading access control policies, loading store data, and cleaning the database of obsolete objects. In runtime environments, run utilities from the Utility server Docker container. In the development environment, run utilities from the bin directory.
  - Shopping flow URLs
    HCL Commerce shopping flow URLs are organized by subsystem.
  - Messaging system URLs
    The following URLs relate to the Messaging system.
  - Scheduler URLs
    The server subsystem consists of functions that are associated with URLs that are run by the scheduler.
  - jQuery Enhancements API
    The Aurora starter store in HCL Commerce is completely written in jQuery, which is one of the most commonly used JavaScript libraries used in dynamic websites. The jQuery AJAX and events API provides an easy to use framework that meets most AJAX requirements for storefront development.
  - HCL Commerce foundation tag library
    The HCL Commerce foundation JSTL tag library is a collection of custom tags that are provided to you to support the authoring of HCL Commerce JSP files. HCL Commerce stores use the JavaServer Pages Standard Tag Library (JSTL) to perform logic, instead of Java code. At the same time, business logic is moved into data beans. The combination of these steps allows for less Java code in a JSP page.
    - Tag: cdata
      The wcf:cdata tag sets the specified data in XML format within a CDATA section and encodes the string that ends a CDATA section to avoid nested CDATA sections.
    - Tag: contextData
      The wcf:contextData tag sets a business context data value for an HCL Commerce service request. The business context data values specified with the wcf:contextData tag are appended to any business context values that are associated with the current session. The new business context values are in effect only for the current HCL Commerce service request. The values do not persist into the session. Use this tag only as a tag of the wcf:getData tag.
    - Deprecated feature: Tag: declareService
      The wcf:declareService tag adds client-side support for invoking a service request. The ID is used to register the specified service so it can be invoked with the wc.service.invoke(serviceId, parameters) function. The parameters parameter is an object map that is passed as parameters to the service URL.
    - Deprecated feature: Tag: declareRenderContext
      The wcf:declareRenderContext tag adds the client-side render context support to the current page. The ID passed to this tag is used to identify the render context. If this tag is already called for this request and ID, then no further call is made.
    - Deprecated feature: Tag: declareRefreshController
      The wcf:declareRefreshController tag declares a refresh area controller. The refresh area controller provides the JavaScript logic that listens to changes in the render context and the model. It refreshes the refresh areas that are registered to the controller. Refresh areas are declared using the wc.widget.RefreshArea widget and by specifying the ID of a declared refresh controller for the controllerId attribute.
    - Tag: defineObjects
      The wcf:defineObjects tag defines the renderContext and businessContext objects in a JSP page. The renderContext object maps render context name and values to single value render context string values. The businessContext object maps business context data names to the current value for the names.
    - Tag: eMarketingSpotCache
      You can include the wcf:eMarketingSpotCache tag within an e-Marketing Spot JSP fragment to indicate that the JSP fragment is to be dynamically cached. This tag dynamically sets dependency IDs for e-Marketing Spot cache entries.
    - Tag: getData
      The wcf:getData tag retrieves data objects from an HCL Commerce service. The wcf:param tag and the wcf:contextData tags are elements of the wcf:getData tag.
    - Tag: json
      The wcf:json tag converts a specified Java object to JavaScript Object Notation (JSON).
    - Tag: metadata
      The wcf:metadata tag retrieves metadata information that can be returned in response to a Get BOD request that is used for authoring. For example, workspaces in Management Center.
    - Tag: param
      The wcf:param tag adds a named parameter value to the parent tag. The wcf:param tag can be specified as a element of the wcf:getData tag.
    - Tag: rest
      The wcf:rest tag sends REST requests.
    - Tag: set
      The wcf:set tag adds values into an object, such as Collections or Maps, that is created with the wcf:useBean tag.
    - Tag: out
      The <wcf:out> tag is used to display the output to the user. This tag provides an option to use an encoding library to encode the output value, protecting against possible cross-site scripting attacks.
    - Tag: url
      The wcf:url tag builds a URL and applies the appropriate HCL Commerce supported rewriting rules.
    - Tag: useBean
      The wcf:useBean tag creates a list or map object.

Deprecated feature: Tag: declareRenderContext

The wcf:declareRenderContext tag adds the client-side render context support to the current page. The ID passed to this tag is used to identify the render context. If this tag is already called for this request and ID, then no further call is made.

Instead of using the wcf:declareRenderContext tag, write JavaScript code.
