EGL Reference Guide for iSeries
EGL provides support for Web-based applications in the following ways:
- You can develop a page handler, which is a logic part whose
functions are each invoked by a specific user action at a Web page.
Generation of this logic part also can provide a JavaServer Faces JSP for
customization.
- You can provide functionality that is common to several Web pages, as when
each page in an application displays a button that the user clicks to log
out. The user's click in this case can invoke an EGL program,
which acts as a common subroutine.
- You may want to retrieve an item of information (such as a stock price) or
cause another action (such as building an output string to send by e-mail)
when the functionality is useful across multiple applications. In this
case, build an EGL Web service, which is a set of operations that can be
invoked by many Internet-based clients. For an overview, see EGL
Web service.
- Finally, when you work in the WebSphere Page Designer, you can customize
JavaServer Faces JSPs and can affect page handlers, as described in Page
Designer Support for EGL.
