Java EE 5 with its immense efforts did many things to make our enterprise apps development process more simple and useful. Introduction of Java EE 6, the latest one has even more simplified designs and architecture processes. It is a reliable and perfect choice for creating small situational apps rapidly and without any overhead burdens. This blog is to show you how various architectures and designing helps smart developers with creation of simple, useful and efficient apps.
There are set of API’s completely independent yet they fit very well together. For Java development you can use JSF 2.0, for transactional services EJB 3.1, CDI for contexts with JPA2.0 and Bean Validation model for implementation of transactions in any app. With mixture of APIs there is totally no need to implement many services. But the main thing here is to select the right subset of APIs which helps in reducing costs and complexity. At the same time also there is absolutely no need for reinvention of wheel with customized coding. But before you find for alternatives be sure to use the present Java SE and Java EE services.
Invented along ...
... with Java EE 6 is CDI that serves the purpose of glue for various parts of specification, management of POJO and used for type-safe mechanism for DI. Also it brings dynamic features like decorators, standardized extension points, service provider interface, events, interceptors etc. CDI is fresh and specifically designed for integration layer still there are overlaps with older technologies. Wherever possible you should use CDI as it has power and also enables you to make application more simplified.
After appropriate packaging of app developer will be able to find separate boundary, package and control. This approach lets you to implement ECB pattern. Easy availability of CDI, JPA2 and EJB all three layers lead to elimination of delegate coding. The pattern and packages in ECB is advantageous where the packages are kept separate and more ease is gained with the use of static analysis tools for measuring dependencies. Boundaries always comes with EJBs while development using Java EE 6. Considering control layers you can either find CDIs or EJBs and in the entity layer either JPA 2 entities or transient can be contained which are known as unmanaged entities. If you are in state of confusion to decide finally to use a CDI or an EJB then initiate with CDI and then turn into EJB using @stateless annotation. Some cases require your using of EJB similarly when you start subsequent transaction. CDI is more suitable for integration of legacy coding or implementing strategy, factory or observer software design patterns. Above discussed abilities are in built and thus results into less coding.
Outsource Java development or offshore java development services for lightweight, fully functional and enterprise level framework that leads you with best implementation to perform efficient practices. For getting such services you need to outsource java development from experienced developers who are proficient in Spring, Tomcat, Java EE 6, JBoss and more.
