The first solution to making the Web more dynamic was Common Gateway Interface (CGI). Unlike static Web retrieval, CGI allows you to create programs that execute when a user makes a request. Say you want to display items for sale on your Web site with a CGI script you can access your product database and display the results. Using simple HTML forms and CGI scripts, you can create a simple storefront that allows you to sell products to anyone with a browser. You can write CGI scripts in any number of languages from Perl to Visual Basic, making the scripts available to a wide range of skill sets. However, CGI is not the safest approach for creating dynamic Web pages. With CGI, you literally let people execute a program on your system. Most of the time this probably isn t a problem, but a user with malicious intent can exploit this and cause your system to run something you didn t intend. Despite that drawback, CGI continues to be used today.

factory that will be responsible for creating aspect instances according to the programmers needs. Finally, Spring AOP default policy is also to instantiate aspects as singleton. Although the framework approach provides default policies, it is always possible to instantiate an aspect dynamically by using a lower-level Java API. In each framework (JAC, JBoss, and Spring), it is thus possible to dynamically add new pieces of advice and introductions to a target object. These features make the framework approach much more flexible than the language approach.

In this example, we are going to let Flash write the necessary HTML and JavaScript code. Here s how:

300 pixels, and set the stage color to #006633 (dark green).

3. Drag an FLVPlayback component to the stage, and specify the following parameters:

When several aspects apply around the same joinpoint, the execution order of these aspects must be specified Most of the time, this ordering depends on the semantics of aspects, and no automatic rules can be defined When considering a trace and a security aspect, for example, the trace may be executed before the security if programmers want to trace every request Alternatively, the security may be executed first if programmers need only tracing requests from unauthorized users In such a case, the programmers must explicitly specify the ordering With AspectJ, aspect ordering is defined with the instruction declare precedence The order is global and applies to the whole application Some ordering may be left unspecified, and in this case, there is no guarantee of the execution order With JAC, aspect ordering is defined with the system property jaccompwrappingOrder.

Figure 3-2. Clicking either of the buttons on the page loads the XML document from the server and displays the appropriate results in an alert box.

4. Save the file as FullScreenSkin.fla. 5. Select File Publish Settings to open the Publish Settings dialog box, as shown in

Figure 10-33.

JBoss AOP uses the tag <precedence> in the XML file jboss-aopxml Spring AOP provides an interface (orgspringframeworkcoreOrdered) that must be implemented to specify the order In all cases, the order is global, and there is no guarantee that some orderings will not be left unspecified At first glance, it may appear that the precedence feature adopted by AspectJ and JBoss is the most powerful, since it allows the ordering of aspects declaration The precedence relationship is transitive, and the aspect system will determine the final order by looking at all the declared orders of all the aspects However, we think that the precedence construct can lead to maintainability issues when refactoring the program (ie, when adding, removing, renaming, or changing aspects) It indeed may happen that all the precedence declarations would need to be changed across the program.

shown in Figure 10-34.

When you published the HTML file, you actually created more than one document: the HTML file and the SWF file, which is embedded in the HTML. The HTML file also contains JavaScript that allows Flash to play in the browser without user interaction (some browsers require users to click in order to indicate their intent to play active content). Technically, these files can all be placed in separate folders, but it requires custom coding. Do yourself a favor and place all of these files (the FLV, SWFs, and HTML documents shown in Figure 10-35) in the same directory when you upload the project to a web server.

processing application. As you can see, Figure 10-36, Flash has written the necessary code that enables the button in lines 26 and 41 of the code block.
