Regardings libs: add commons-pool.jar from jakarta, and exlcude servlet.jar for building the war file. ... then it runs like a charme. Very nice article, Thanks! -- Niko

Vladimir Cholak wrote: What does the author teach regarding decoupling presentation tier from business tier? Just look at Listing 1. At one line the author demonstrate how to call business method indirectly via ServiceLocator. It's OK. But at the next line he breaks that principle and call business method directly. Why don't he use the same principle? It should be done like this: this.getServiceLocator().getCartService().addItem(item); And of course, the reference to Cart business object should be removed from CartBean.

mike wrote: It is a really great artical and if you are a Java programer (developer/architect) you can learn a lot. At the same time it shows why J2EE application development sucks (big time). One has to download Spring (13M), Hibernate(15M) and spend a couple of hours just to make this application working. I guess it is not worth mentioning how much time it takes to learn both of those frameworks. Or that the author himself concedes "JSF technology is not mature at this stage". So just go ahead learn this new exciting technology though you probably will not be able to use it soon for real applications. I live off Java but it is getting more (unnecessary) complicated with each new day (each new second). Like JSP 2.0 EL (expression language), for example. Could anybody explain me why is '${1 + 2}' better than '<%=(1+2)%>'? I do have opportunity to see various experts, senior developers, architects...
