CommandFactory.createCommand() method



This method searches the command registry(CMDREG table) for an entry corresponding to the specified command name (Interface)and storeId. if no entry is found for specified store, it will look for an entry corresponding to storeId=0. if both fail, it will check for a default implementation of the command from the interface and returns an entry that represent the default implementation of the interface.
Ex:

static final String defaultCommandClassName = "com.ibm.commerce.sample.commands.MyNewControllerCmdImpl";

so, when you make a command with the CommandFactory class, you need to pass in the interface name, rather than the implementation class, since the field looked up in the database is the CMDREG.INTERFACE field.

if you specify the implementation class (MyNewControllerCmdImpl) rather than the interface (MyNewControllerCmd) may result in a ClassNotFoundException.

Dataload Utility In WCS

Data can be loaded into WCS tables using data load utility.   WCS Data Load utility performs the following functions in a single operation: 1.              Reads the data from the input source file. 2.              Transforms the source data to WebSphere Commerce business objects. 3.              Allocates and resolves WebSphere Commerce business objects to physical data. 4.              Loads the physical data into the database. There are three configurations files and a input source file required to complete the data loader setup. WCS supports only CSV File Reader for other input source you have to write your own Reader Class. This means that if you are using OOB CSVReader then your input file must be a CSV file. The three configuration files are listed below. 1.              wc-dataload-env.xml 2.              wc-dataload-loader.xml 3.              wc-dataload.xml wc-dataload-env.xml holds the environment settings such as database name,encrypted password,data

1. Explain WCS Archetecture WebSphere Commerce functional architecture Descriptions: Controller layer 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. Presentation layer The presentation layer displays the result of command execution. The presentation layer can use JSP pages, or other rendering technologies. Business Context Service (BCS) A service that manages contextual information used by business components. The contexts include such information as globalization and entitlement.
