Built-In Internationalization Support generate, create none none with none projectscreate ean 13 A Java platform itself provid none for none es substantial support for internationalization and localization but, in Tapestry we do not need to know the details of that support. We just use a few simple hooks provided by the framework to have our application displayed in as many different languages as we wish. It is actually quite amazing to see how one mouse click totally changes the language of the application.

Everything text, images, different controls, suddenly begin to speak in a foreign language! It is an impressive feature, considering how little we have to do to enable this flexibility.. Bar Code Scanner Environments [ 10 ]. 1 . Inversion of Control Made Easy Inversion of Control (IoC) an none for none d Dependency Injection are amongst the most popular software development paradigms these days, and they deserve their popularity. In simple terms, Inversion of Control allows developers to save effort and time by allowing some other software to take care of different routine things and provide them services whenever needed. However, to use the benefits of Inversion of Control in an application, one might need to learn and use an additional framework like Spring.

Not in Tapestry though. Tapestry has an Inversion of Control subsystem of its own, and quite a good one. As a result, Tapestry applications contain very little Java code.

All you need to write is business logic while all the infrastructure issues are handled automatically. Aditionally, the Tapestry 5 IoC container additionally provides an opportunity to implement and enforce some of the best design patterns, again, with absolute minimum code serving this purpose. Spring framework is very popular, and working on a large-scale enterprise application, we often need to make use of some sort of back end, implemented in Spring.

Thankfully, Tapestry has a special subsystem for integration with Spring. Using this subsystem in my work, I had an impression that it is easier to use Spring beans in Tapestry than in Spring itself. More or less the same can be said about integration with another very popular framework, Hibernate.

There is a special subsystem in Tapestry responsible for this integration and it is very easy to use. To summarize, Tapestry is a mature contemporary web development framework with all the features that would be expected from such a framework and with all the power of Java platform to support it. But additionally, Tapestry is based on a unique, developer-friendly paradigm, which makes it especially easy to learn and use.

. Is Tapestry the Savior in the World of Java Web Development Java technology is traditiona none none lly strong on the server side. However, in the last couple of years one might notice some kind of stagnation in the area of Java web development. To explain what I mean, I will need to show you a brief history of Java web development.

. [ 11 ]. Introduction to Tapestry In the first stage of web dev elopment, it was typical to have some code that a web server could invoke to produce dynamic content. The traditional solution is to have a program written in Perl or C and to invoke it through a CGI interface. The Java solution was different however, and that solution was rather advanced for its time.

Java code was running on the server as a servlet, a kind of plug-in maintained by a servlet container. The servlet way was superior because it ensured higher scalability, but perhaps even more importantly from the developer"s point of view, a servlet developer could spend more time writing application-specific code, since many of the lower level issues were handled by the servlet container. At that time, Java technology was ahead of the rest of the web development world.

The next generation of web technology was about embedding pieces of code into an HTML page in order to make it dynamic. You can see this approach in JSP, ASP, PHP and ColdFusion. Again, Java technology was ahead, because JavaServer Pages took special care about separation between the application code and its presentation logic.

Ideologically fortified by Model-View-Controller design pattern, this approach culminated in Apache Struts framework. Basically, a Struts application is a traditional servlet/JSP application, but this framework offered a number of efficient solutions for common problems of web development. Struts developers could avoid reinventing the wheel and reuse existing solutions by modifying them with application-specific code.

This significantly increased the efficiency of large-scale web development, and Struts framework became extremely popular, once again ensuring the leading position of Java technologies. However, around the same time Microsoft came up with an alternative technological solution, ASP.NET.

This was a component-based approach which was supported by a sophisticated integrated development environment (IDE), Visual Studio, ASP.NET resembles RAD solutions that brought desktop development to a new level of productivity some years ago. An ASP.

NET developer can drop a few components on the page, set their properties in a visual property editor and run the application all in just a few seconds. This is when the feeling appeared that the Java approach is not quite the best anymore. ASP.

NET was quickly gaining popularity, while the mainstream Java approach was exemplified by a Struts application, not component-based, and was still quite a low-level solution. The Java world tried to retaliate by creating JavaServer Faces specification. Externally, it resembles ASP.

NET, but is built on top of the existing Java-specific solutions.. [ 12 ].
