Hello there. Welcome to our Java EE 7 certification exam course. This course is intended specifically for individuals who wish to earn the Oracle certitified associate OCA, Java EE 7 application developer certification, which exam number 1Z0-900. It assumes that you're familiar with Java and have some experience working with it. If you are completely new to Java or to object oriented languages, I suggest that you start your journey with an entry level course, get some experience, and then come back to this one. The information in this section is outsourced from oracle.com, public websites, and user forums. Input has been taken from real people who have earned Java certification. All efforts have been made to maintain the accuracy of the content, but the details of the exam, including the exam objectives, pricing, exam pass score, total number of questions, maximum exam duration and others are subject to change per Oracle's policies.
The Oracle Certified Associate OCA Java EE 7 application developer exam covers the fundamentals of Java EE 7 programming, such as the importance of Java message service, fundamentals of web and web services, JSON processing, JAX and RS API, Servlet technology and other stuff. If you pass this exam, you can earn the title of Oracle Certified Professional OCP Java EE 7 application developer. It certifies that an individual possesses a strong foundation in the Java programming language. What is Java SE and Java EE? What are the differences? Both a programming language and a platform, Java is a high-level object-oriented programming language with a specific syntax and style. Java platforms are the environments in which Java software language applications are developed and run. To briefly describe the Java platforms, there are several Java platforms in the Java programming language. These are Java platform Standard Edition, Java SE, Java platform Enterprise Edition, Java EE, Java platform Micro Edition, Java ME, and Java FX Name.
All these mentioned Java platforms provide a Java virtual machine, VM, and an application programming interface, API. Thus, it allows applications written for that platform to run on any system compatible with all the advantages of the Java programming language, such as platform independence, power, stability, ease of development, and security. When most people think of the Java programming language, the Java platform Standard Edition or Java SE API comes to mind. Java SE API provides the core functionality of the Java programming language. It defines everything from the basic types and objects of the Java programming language, the high-level classes used for networking, security, database access, graphical user interface, GUI, development, and XML parsing. But a virtual machine is common in development tools, deployment technologies, and Java technology applications. It consists of other class libraries and tool kits.
In addition, Java SE is used to develop applications that are standalone programs that run on desktop computers, and applications that are programs that run in web browsers. Java platform Enterprise Edition, namely the Java EE platform, is built on top of the Java SE platform. The Java EE platform provides an API for developing and running reliable, multi-tiered, large-scale, and scalable web-based applications. It represents collaboration between multiple vendors and industry leaders, and provides infrastructure support for applications. Simply put, it's used to develop enterprise-oriented applications and server applications. The feature that will make the difference between the two platforms is that Java SE is used for all standard applications while Java EE is used specifically for transaction management and security. Java Enterprise Edition, Java EE, provides a standards-based platform for developing web and enterprise applications.
These applications are typically designed as multi-layer applications with a front-end layer consisting of a web framework, a middle layer providing security and operations, and a back-end layer providing connectivity to a database or legacy system. These apps must be responsive and scalable to adapt to growth in user demand. The Java EE platform defines APIs for the different components in each layer and also provides some additional services, such as naming, embedding, and resource management that spanned the platform. These components are deployed in containers that provide runtime support. Containers provide a unified view of the underlying Java EE APIs to application components. Java EE application components never interact directly with other Java EE application components. They use the container's protocols and methods to interact with each other and with platform services.
Placing a container between application components and Java EE services allows the container to transparently inject the services required by the component, such as declaritive transaction management, security controls, resource pooling, and state management. This container-based model, an abstraction of resource access, allows the platform to distract the developer from common infrastructure tasks. Each component of the platform is defined in a separate specification that also describes the API Java docks and expected runtime behavior. Java EE 7 was released in June 2013 and provides a simple, easy to use, and complete stack for building such web and enterprise applications. Previous versions of the platform, starting with Java EE 5 and continuing with Java EE 6, took the first steps in providing a simplified developer experience. So, that's it. Hope to see you again. Have a nice day.
