Web components, which are known as Web applications, can consist of any combination of the following parts:
To enable Web applications for use, your Web-serving environment requires an HTTP transport (to receive HTTP requests from a network of browsers using the HTTP access protocol) and an execution environment (to interpret the inbound request and run the appropriate servlet, based on the contents of the inbound request). The WebSphere Application Server for z/OS J2EE server includes a choice of two HTTP transports and execution environments:
Recommendation: Because the Application Server is not designed to directly host static content (for example, HTML pages), the recommended configuration places a Web server with a plug-in in front of the Application Server.
Web applications running in the Web container have direct access to resources on z/OS or OS/390, or can access them through enterprise beans running in any WebSphere Application Server for z/OS server. Web applications use the RMI/IIOP protocol to access enterprise beans running in J2EE servers on the same or different z/OS or OS/390 images.
For more information about deploying Web applications, see the assembling applications information in the WebSphere Application Server for z/OS InfoCenter.
