Developing
The topics in the Developing section describe tasks performed by an application developer.
Controller layer
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.
Integrating with back-end systems and external applications
External systems integration is a key feature of the WebSphere Commerce solution. In WebSphere Commerce business logic is enabled for integration and built-in adapters and interfaces are provided for common integration points. Additionally, the WebSphere Commerce integration solution leverages integration standards by using various IBM connectivity solutions.
Back-end integration legacy messages
The WebSphere Commerce offers support for messages which use the legacy message format. Unless you are migrating from a previous version of WebSphere Commerce Suite, it is recommended that you use the XML messages instead, since they accomplish the same function, and are easier to read and maintain.
Product Quantity Update message
The Product Quantity Update message is an inbound message that contains inventory information for a product. A back-end application generates this message and sends it to the WebSphere Commerce inbound message queue, where the WebSphere Commerce system receives the message.

Product Quantity Update message

The Product Quantity Update message is an inbound message that contains inventory information for a product. A back-end application generates this message and sends it to the WebSphere Commerce inbound message queue, where the WebSphere Commerce system receives the message.

The Product Quantity Update message uses the WebSphere Commerce message format and consists of a set of records, which follow each other sequentially in a data buffer. The following data describes the Product Quantity Update message:


<ECEDOC>

<PROLOG>PRODUCT_QUANTITY_UPDATE_PROLOG_DATA</PROLOG>

<HEADER>

    <HDR010>PRODUCT_QUANTITY_UPDATE_HDR010_DATA</HDR010>

</HEADER>

</ECEDOC>

Notes:

All records are in sequential order in the buffer. Indentation is used here for readability; it does not appear in the buffer.
All fields in the data segments are left-justified and padded to the right with spaces in the buffer.
