You ll rarely ever distribute a library by itself. Instead, you typically will bundle a library with one or more applications. There are several benefits to doing this. It allows you to encapsulate functions and separate them from the application. If you have multiple apps that need to decode videos, then rather than writing video decoding functions and copying them to both apps, you could just place those functions within a library. When you fix bugs or add new video formats to decode, you only need to update the library. Libraries can also be useful for performing simple tasks that don t require user interaction. You might use a library that scans for temporary files left behind by your main app and cleans them up, or that tells the device to start your application when the user receives a particular email.

Note Remember, clustered indexes hold the data, and not pointers to the data. However, in this instance,

Testing the presentation layer components is not notably different from testing the service layer. Again, we have a layer that predominantly performs its actions by calling through to another layer (although here we are one level higher up calling into the service layer instead of into the DAO layer). The source code available from the Source Code/Download area of the Apress website (www.apress.com) includes an EasyMock-based test of a Spring MVC controller and its validation class. Testing a Spring Web Flow implementation class presents an additional challenge, however. The configuration of the test shown in Listing 10-28 is very much as you would expect: the only real departure from the sort of mock object based testing we have seen before is the creation (shown in bold) and use of the MockRequestContext object. This object is provided as a standard part of the Web Flow libraries specifically to make testing easier.

Now that you have started specifying some parameters for msbuild.exe, you may be interested in what other options are available. Table 2-3 summarizes those options. Table 2-3. msbuild.exe Command-Line Parameters

In a number of deployments Entourage simply will not work, even though Outlook Web Access will authenticate users. To resolve this, we often use a series of Windows PowerShell commands. PowerShell is the command-line scripting language used for Windows Server 2008 and Exchange Server 2007 environments. To start off, we ll get a list of all of the virtual directories using the Get-OwaVirtualDirectory cmdlet without any operators:

1. First of all, let s create our stored procedure. We have our CREATE PROCEDURE statement that we enter in an empty Query Editor pane, and then we name the procedure with our three input parameters. CREATE PROCEDURE CustomerDetails.apf_CustMovement @CustId bigint, @FromDate datetime, @ToDate datetime AS BEGIN
