WebSphere Commerce Server

WebSphere Commerce Payments Server

Note: The WebSphere Commerce node architecture depicted in Figure 2-1 on page 10 shows a single-node configuration. The software components listed in this section can be distributed on separate nodes for scalability and security reasons.

2.2.1 Web server

The Web server can be installed on the WebSphere Commerce node or a remote node, which can be optionally clustered for load balancing using the WebSphere Application Server V5, Network Deployment Edition Edge components. Regardless of whether the Web server is local or remote, it must be configured to use the WebSphere Application Server plug-in. There are several supported Web server plug-ins. The IBM HTTP Server and plug-in are found on the WebSphere Application Server CD included with WebSphere Commerce.

The majority of the WebSphere Commerce tooling and store application assets are J2EE components (JSPs, servlets, EJBs, etc.) that run on the application server located on the WebSphere Commerce node. There are some static HTML pages and images found in the WebSphere Commerce tools and stores that can be served by the Web server.

Incoming HTTP requests from Web browser clients are received by the Web server and WebSphere plug-in. The WebSphere plug-in, via the use of the plugin-cfg.xml file, redirects requests to applications on the WebSphere Application Server on the WebSphere Commerce node.

2.2.2 WebSphere Application Server

The WebSphere Commerce Server leverages the J2EE technologies provided by the WebSphere Application Server such as JSPs, servlets (WebSphere Commerce commands), EJBs, XML, Web Services, security, MQ embedded messaging, etc.

IBM WebSphere Commerce V5.6 includes the IBM WebSphere Application Server V5 base edition and Network Deployment Edition. The base edition is suitable for single-node and multi-node runtime configurations. When multiple WebSphere Application Servers are needed for scalability, such as horizontal application clustering, then the Network Deployment Edition is needed.
