In the preceding example, the element has four child elements, each of which contains textual information. Many of these can be used together. In the shopping cart example, only the server page elements were mapped to the GetCart. Interfaces for stubs are defined in IDL, which defines the operations and the parameters that a particular object can implement.

Despite the early hype about object-oriented programming languages and their ability to reuse off-the-shelf classes to build bigger and more complex applications, the reuse of discrete classes never came to be. If we were to look at the generated page, there would be only a few fields and buttons showing Figure In normal COM, the communication between the client and server objects that are in different process spaces is managed by the distributed computing environment’s DCE remote procedure call RPC mechanism.

The customer tells the system to display the overview of the product catalog. The problem stems from the fact that if a browser doesn’t understand a tag, it just ignores it.

This gives Java Server Pages some performance benefits over the other scripted-page offerings. Writing in-line scripts that initialize the page before the user starts to interact with it might be OK to write this way, although I still wouldn’t encourage it.

This depth of functionality is very important to ji, in mind when designing clientside activity. This means that an ActiveX component can control the content of the Web page it originally came in with, just as the JavaScript examples did earlier.

Every instance of an RMI-enabled program must install and run a security manager conalldn. Chapter 2, Web Application Basics, is an introduction to the very basic Web application applicatons. The majority of the original work of this book is in Chapters 10 and It defines buuilding object hierarchy that page scripts use to access the information in the document and even the browser itself.


Figure shows the same Rose specifications dialog and ASP tool settings only this time scrolled downshowing the onLoad event tagged value setting. Because a document is a collaboration of objects, it applocations be represented by an object model. Chapter 7 discusses the activities of defining the architecture of a Applicatiohs application. The script applicagions begins with the following: With this book as your guide, you will be able to gain a clear understanding of how to address the unique problems of modeling the design of page-based Web applications, and more important, how to take your model directly into working code.

Since JavaScript doesn’t follow the same formatting or structuring rules as HTML, it is probable that an older browser will react badly and report a large number of warnings or errors. CORBA supports multiple languages. The contents of a frame may be a Web page or another frameset.

The Document Object Model standard is a good place to start. Scripted pages are used mostly as the glue that connects app,ications HTML user interface aspects of the system with the business logic components. For a Web application to effectively make use of distributed objects, there must be a way to automatically send to the client the necessary objects and interfaces needed for it to participate in the system without having the user stop the application and install special software.
