It is important to understand that there are a number of major differences between building web applications and building standard Windows client applications. If you are coming to web development from a Windows client development background, there are several aspects of web development that are significantly different from Windows client application development. Most Windows applications are designed to work with a single user, but web applications that don t scale to thousands of users are considered a failure. Also, the application from a user s perspective executes in a web browser, so local file system permissions and system access is very limited. And perhaps the hardest concept to grasp if you re used to virtually unlimited memory and computational horsepower is that web applications are by and large stateless, meaning that information isn t retained on the server between page invocations. (There are techniques to bypass this obstacle, but even those require some design thought.) java qr code reader for mobile Read QR Code content with Selenium and zxing – Elias Nogueira ...

QRGen is a good library that creates a layer on top of ZXing and makes QR Code generation in Java a piece of cake. Up until now, we have called web methods synchronously. That means that unless the web method is not finished, our form processing is blocked. Synchronous calls are what you need in most applications, but at times you may need to call web methods in asynchronous fashion. Imagine that you are developing a portal by using ASP.NET 2.0. As a part of the feature set, you want to provide a facility whereby users can get a comparative price list of computer books. The users will specify a book title whose price list is to be generated. To obtain the cost of the book, you consume web services exposed by various book suppliers. That means for a book title you call many web methods that return the cost of the title by individual suppliers. You then collectively display the costs to the user. If you call the web methods in synchronous fashion, the total time taken will be the summation of the processing time taken by the individual web methods. On the other hand, if you call the web methods in asynchronous fashion, the time taken will be reduced to the processing time taken by the lengthiest web method (see Figure 9-14). qr code reader java download Java QR Code Reader Library to read, scan QR Code barcode ...

Apart from barcode scanning , it serves multiple purposes including face detection. Web applications are multiuser: When building an application for the Web, you have to remember that your application should be designed to be scaled out to many users, which in some cases can number in the millions This leads to two major challenges The first is that when the application has to scale out to huge numbers of users, it will operate in a clustered environment, meaning that it is deployed to a number of servers, and the clustering hardware manages who speaks to which server In an environment such as this, you have to make sure that the experience each user has when using your application is consistent Thus, a level of commonality is necessary, and this is achieved using shared pools of resources such as data, styling, and connectivity to outside applications. 13 Most of the time, writing a portlet is not so different from writing a servlet, but in one unexpected aspect they really are quite different: you cannot render URLs directly if you want the link to appear within the portlet rather than as a page in its own right. You have to make sure that your application cooperates with other instances of itself in accessing shared application resources Similarly, you have to make sure that the users accessing your application are doing so concurrently, leading to potential concurrency issues This means that you have to be careful in how you write classes that are going to be shared by user sessions The framework helps you in this regard, but it doesn t do everything for you Your user classes will need to be carefully crafted and deployed Web applications are designed to execute on a server and be viewed in a browser: Your application is used within users browsers on their machines, but the application actually executes (for the most part) on your server. qr code scanner for java mobile QR Code Reader Java App - Download for free on PHONEKY
