I ran into Tapestry late in its life. When I started using Tapestry, version 3.0 had just been released. At that point it was obvious to me that Tapestry was a robust, fully-featured Web framework.

User references If workflow processes include references to specific users, Microsoft Dynamics CRM will maintain the user reference if you import the process to a target system on the same Microsoft Active Directory domain. If you import workflow processes between two different domains or into a Microsoft Dynamics CRM instance that does not contain the specified user, you need to update all of the user references manually before you can publish the imported process. You will receive a warning at the end of the solution import indicating that the user is missing and the process will remain deactivated.

Optional Certi cate for Token Encryption (Issuer, Browser Scenario) The certi cate for token encryption secures the SAML token. Encrypting tokens is optional, but it is recommended. For example, you may opt to rely on TLS/SSL that will secure the whole channel.

If you are accepting confidential information over the Web (such as credit card numbers or social security data), you need to make sure that transmission and receipt of information is secure. Normally, web information is broadcast in plain text, and the very nature of the foundation technology used by the Internet means that all information is passed through many different computers and routing points. That means that information can possibly be intercepted.

The following questions are intended to reinforce key information presented in this lesson. If you are unable to answer a question, review the lesson materials and try the question again. You can find answers to the questions in the Questions and Answers section at the end of this chapter. 1. You install a new application, which reports that it is installing a service on the computer. However, when you run the application for the first time, it is unable to start. You inspect the event log to determine the nature of the problem. You receive an error stating The service did not start due to a logon failure. What should you do a. Grant the account the Logon As A Service right. b. Change the password to the same name as the account. c. Verify the user name of the account being used to run the service. d. Grant the account administrative rights. 2. You install a new application, which reports that it is installing a service on the computer. However, when you run the application for the first time, it is unable to start. You inspect the service dependencies for the new service and notice that a service that is required is not started. However, your security policy states that ser vices must remain stopped unless another application requires them to be on. How should you configure the dependent service to start

// Initializes Array object $results = array (); // Format results $results = $this->DataFormat($result); // Returns results return $results; } Let s have a look now at GetAmazonDataWithRest() and GetAmazonDataWithSoap(), which are the methods that do the actual communication with ECS. GetAmazonDataWithRest() retrieves Web Service data using REST. It starts by constructing the required query string by joining the individual parameters you want to send to Amazon: // Call ECS using REST private function GetDataWithRest() { $params = array ('Operation' => 'ItemSearch', 'SubscriptionId' => AMAZON_ACCESS_KEY_ID, 'Keywords' => AMAZON_SEARCH_KEYWORDS, 'SearchIndex' => AMAZON_SEARCH_NODE, 'ResponseGroup' => AMAZON_RESPONSE_GROUPS, 'Sort' => 'salesrank'); $query_string = '&'; foreach ($params as $key => $value) $query_string .= $key . '=' . urlencode($value) . '&'; The complete Amazon URL that you need to call is composed of the base URL (which you saved as a constant in include/config.php) to which you append the query string you just built: $amazon_url = AMAZON_REST_BASE_URL . $query_string; Using the file_get_contents() function, you make a simple HTTP GET request to Amazon. It's just like typing the address in your browser: // Get the XML response using REST $amazon_xml = file_get_contents($amazon_url); The $amazon_xml variable will contain a string with the returned XML data. To further process it, we use the simplexml_load_string() function that parses the XML text and returns a SimpleXMLElement object representing the XML document. Read more details at http://www.php.net/manual/en/ function.simplexml-load-string.php. // Unserialize the XML and return return simplexml_load_string($amazon_xml); } The GetAmazonDataWithSoap() method has similar functionality as GetAmazonDataWithRest(), but it makes the ItemSearch operation using SOAP. The logic this method uses to contact ECS is the same as in the page you wrote earlier in this chapter.

It offers a training module as well:

// This function takes a string input, converts it to a number array, and applies a // mathematical formula to check the number's ability to meet the criteria for a valid // Mod 10 number and returns a Boolean result. A0 public static bool IsValidMod10Number (string number) { int[] numberArray = new int[number.Length]; bool checkBit = false; int sumTotal = 0; A1 for (int i = 0; i < number.Length; i++) { numberArray[i] = int.Parse(number.Substring(i, 1)); }

Here, the parent task creates and starts three Task objects . By default, Task objects created by another task are top-level tasks that have no relationship to the task that creates them . However, the TaskCreationOptions.AttachedToParent flag associates a Task with the Task that creates it so that the creating task is not considered finished until all its children (and grandchildren) have finished running . When creating a Task by calling the ContinueWith method, you can make the continue-with task be a child by specifying the TaskContinuationOptions.AttachedToParent flag .

Windows Server 2008 is entirely roles-based in how you manage it. There is no longer a concept of installing many separate and unrelated components the way there was in older server operating systems. In Windows Server 2008 you decide what role you wish your server to play and the Server Manager tool provisions it with the necessary software to do that. Microsoft distinguishes between roles and features. A role is a collection of software that collectively enables the server to provide some service to the network. Generally, a role is what you bought the server for. An example of a role is Domain Controller or Application Server (such as a Web server with application frameworks). Often a role can be installed in one step, but may require significant configuration to function the way you want it to. For instance, you can easily promote a server to become a Domain Controller but unless you add user and computer accounts to it, having a DC does not do much good. Features, on the other hand, are simpler. They are things that many servers need, and that there is a good reason to have, but that you may not consider as the primary reason you bought the server. They do not describe the server in the way roles do. In some cases, features involve no services at all, as is the case with the Recovery Disk feature, which is just a tool. Other features do have services associated with them. In many cases, a feature is simply a way to surface the installation of a service to an administrator. Many of the things you saw under the Programs And Features Control Panel in Windows Vista are listed as features in Windows Server 2008. In some cases, the distinction between roles and features is quite unclear. For example, Dynamic Host Configuration Protocol (DHCP) and Domain Name Service (DNS) are both roles, but Windows Internet Name Service (WINS) is a feature. WINS keeps track of DHCP-assigned Internet Protocol (IP) addresses and provides the same services for legacy Windows networks that DNS provides for up-level ones. As you go through the features, you will find that some optional components slated for deprecation are listed as features. This is now the only way to install them. Some roles require certain features to work. For instance, the Active Directory Rights Management Services (AD RMS) role requires the Windows Internal Database feature (Microsoft SQL Server 2005 Embedded Edition). Likewise, some features may require other features, as is the case with Windows System Resource Manager (WSRM), which also requires the Windows Internal Database. In many cases, the links between features and roles are quite intricate. For example, consider the case of an Application Server. If you attempt to install that role on a freshly laid down server you are asked to install two features .NET Framework 3.0 Features and Windows Process Activation as shown in Figure 11-1. Unless you specifically modify the default selections you will get all the roles and features installed that are needed for the essential services of the particular role, along with the basic
