Oracle Enterprise Business Suite Development: New Technologies

We have already talked about the importance of Java Technologies at Oracle Enterprise Business Suite in Bangalore. Not only for Oracle Company itself, but also for the Oracle Enterprise Business customers, whose investments must be preserved. Now we present tools and frameworks, you will use if you intend to develop in Java

 Java Language Itself: is an object oriented language, so if you are not used with this     paradigm, we strongly advice you to study this already established     paradigm. To develop in Java you will use a lot of standards and     libraries, they are known by its name, J2ME, J2SE and J2EE, to portable,     standard and enterprise applications respectively;

JDeveloper: is an     integrated development environment (IDE) built in Java for Java     development. It is complete considering the development life cycle, so you     can model, code, debug, test and deploy. It is prepared for Web, XML, Web     Services, SQL, J2EE and Oracle ADF development. Provide built-in features     for open sources tools and frameworks, such as Struts, Ant, JUnit and CVS.     According to Oracle, JDeveloper is the tool of choice for Forms, Reports     and Designer customers because it carries a similar development model.

Struts: is a     java framework considered a de facto standard to build     web applications. Struts is a solution to organize what was happing when     people used Java Servlets and JSP freely. Struts implements the MVC (Model     / View / Controller) pattern, so you might separate business logic (Model)     from web application flow of control (Controller) and JSP/html code     (View).

J2EE: is an     architecture to define standards to solve enterprise level problems, like     persistence, scalability, availability, security, distributed computing,     etc. This standard should be followed by application server vendors, so a     J2EE application would run on any J2EE application server complaint, like     Oracle OC4J (OAS), IBM WebSphere, BEA WebLogic, JBoss, etc. It is not a     simple architecture to solve a simple problem. Get ready to study and     understand the complexity of enterprise programming (we will deal with     this matter on others papers to help you).

EJB: is a     J2EE standard to define components to write business logic at the server     side (Session Beans), to define a domain layer to access data (Entity     Beans) and to deal with asynchronous and queuing messages (Message Driven     Beans). The last EJB standard release (the 3.0), not commonly used yet,     became much easier to develop with. The previous one (the 2.0 and 2.1)     should be used with a series of design patterns to solve common problems,     what make the code not so easy to program and understand. The first one     (the 1.0 and 1.1) was useless to enterprise level development; it did not     implement even a one to many relationship.

Oracle ADF:     according to Oracle, ADF is an application development framework design to     simplify J2EE development and bring productivity and ease of use of Oracle     forms to the J2EE platform. ADF with JDeveloper is the best choice for     Oracle Enterprise Business Suite in Bangalore, because Oracle made this     environment familiar to Oracle Forms, Reports and Designer     developers.
