Figure 6-3 shows a square that represents the view port. The view port is the visible map pieces as viewed by an HTML page. Each view port can display four complete map pieces, and it provides four ways to navigate. In Figure 6-3, an arrow pointing north is shown, indicating that the user wants to move the view port north. Based on this configuration, let s walk through how the architecture in Figure 6-2 can be implemented as a series of steps: 1. The client surfs to the URL and loads the HTML page that contains the view port. 2. The HTML page sends a POST asking to load four map pieces. 3. TaskManager begins a task that retrieves the requested map pieces. The task adds the map pieces to ResultCache. 4. The HTML page executes a periodic loop that asks if the requested map pieces have been added to ResultCache. If the pieces have been added, then they are retrieved and displayed. At this moment, there is a disconnect, as the identifier of the map pieces has not been defined. When the HTML page loads, which map pieces are loaded Do you load the default And if you do load the default, what exactly is the default When loading the map pieces, you need to first determine how to identify a map piece. The best strategy is to use a coordinate system, as shown in Figure 6-4.

After reading this output, you can definitely see the options that you just set. Likewise, you can verify that the settings have properly updated in Server Admin. Note: Global and per-user password policies do not apply to Open Directory Administrator accounts.

disable auto-restart when invoking the browser this way. The following code demonstrates how to do this.

When first deploying systems to hundreds of users, it is likely that you will first utilize a standard password or password pattern so that users can successfully login for the first time. However, as you will likely often need to disseminate this information in an unsafe manner (such as email), it is important that you ensure that users reset their passwords to a personal value as soon as possible. To do this, you can modify the global password policy to force a password change upon first login. To accomplish this, you can simply check the option for the password to Be reset at first login. Alternatively, you can set this option using pwpolicy:

int handle = CodeModuleManager.getModuleHandle("net_rim_bb_browser_daemon"); if (handle > 0) { ApplicationDescriptor[] descriptors = CodeModuleManager.getApplicationDescriptors(handle); String[] args = {"url", "file:///SDCard/BlackBerry/temp/awards.3gp", null}; // Turn off auto-restart. int flags = descriptors[0].getFlags(); flags = flags ^ ApplicationDescriptor.FLAG_AUTO_RESTART; ApplicationDescriptor newDescriptor = new ApplicationDescriptor ( descriptors[0], "BrowserPS", args, null, -1, null, -1, flags); ApplicationManager.getApplicationManager().runApplication(newDescriptor); }

When a method is assigned to any object, there can only be one instance of that property. It is not possible in JavaScript to assign multiple same-named properties. For example, the following code will not work. Source: /website/ROOT/ajaxrecipes/javascript/overloaded.html var cls = new Object(); cls[ "method"] = function() { info( "method1", "hello"); } cls.method(); cls[ "method"] = function() { info( "method2", "hello"); } cls.method(); In the example code, there are two assignments to the method property. The cls.method method is called twice, and for each call the function implementation called is the last assignment value. The code is trivial and is meant to illustrate that you cannot overload a method by assigning it. Overloading a method is useful in situations where a variable number of parameters are going to be called on a method. Since there are no type declarations, overloaded methods will vary in the number of parameters. The logic used is that if the method is called with five parameters, then an overloaded method that processes five parameters will be called. If the overloaded method does not exist, the default implementation that was initially assigned to the property will be used. The solution to overloading a method lies in using the same solutions shown in Recipes 2-16 and 2-17. (If you have not yet read those recipes, I advise that you do so before continuing, as I do not repeat the underlying theory of those recipes here.) To implement an overloaded method architecture, the same architecture of the proxy and delegate implementation will be used, as shown in Figure 2-9.
