Oracle Java Certifications

Welcome to Java Certification Path. If you are reading this article, it means that you are thinking or have decided to take Java Certification. Let me start off by congratulating you on this decision to boost your career strength.

To become a successful Java professional it is good to acquire Java certification to show their evidence. Java certifications adds more confidence to your job responsibilities as well as improves your career potential, of-course you can get higher salary than others.

Oracle’s Java certifications are designed to be focused on particular roles in the software development cycle and, therefore, are more useful than all-in-one certifications.

Oracle currently offers the following Java certifications, which are classified by level and specialization. Most of the certifications require you to pass a multiple choice exam, but some require you to complete an assignment plus an essay exam.

The Java certification program consists of following exams based on platform and levels:

Java SE Programmer exams - The Java Programmer exams tests the candidate's Object Oriented Concept knowledge of the Java language and basic application programming interface (API) packages. The latest exams from Oracle are OCA Java SE 7 Programmer I Exam and OCP Java SE 7 Programmer II Exam.

Java ME Developer exams - The Java ME Developer exam tests the candidate's J2ME knowledge to develop mobile applications. OCP Java Programmer certification (any version) is a prerequisite to take Java ME Developer Exam.

Java SE Developer exam - The Java SE Developer exam is different from programmer exams and it tests the candidate's ability to complete an extended programming assignment and answer questions about issues and trade-offs involved in completing the assignment. OCP Java Programmer certification (any version) is a prerequisite to take Java Developer Assignment Exam.

Java EE Architect exam - The Java EE Architect exam style is similar to developer exam but it requires you to complete 3 steps. The exam tests candidate's architecture knowledge required to design Java EE applications using best practices and patterns.

Step 1: You have to complete multiple choice exam.
Step 2: You have to submit architecture solution for the given business problem.
Step 3: Justify your architecture solution by answering few questions.

Java EE 5 Developer exams - These exams are based on Java EE Tier Components.
Web Component Developer exam to tests JSP and Servlet knowledge.
Business Component Developer exam to tests EJB and JPA knowledge.
Web Services Developer exam to tests Java EE 5 webservices APIs.

Java EE 6 Expert Exams - These exams are based on components instead of Java EE tiers. Note that in Java EE 5 developer exams EJB and JPA is combined in single exam whereas in expert level it is divided into two.

OCE Web Component - Tests Java EE 6 JSP and Servlet changes like annotations, asynchronous request processing, etc.
OCE EJB - Tests new changes like Singleton Session Beans, timer improvements in EJB, asynchronous session beans etc.
OCE JPA - Must focus more on criteria query API along with other exam objectives.
OCE Web Services - New API JAX-RS for JSON based webservices is hot in this certification.

How can I gain these super powers? In his session at 17th Cloud Expo, Chris Matthieu, co-founder and CTO of Octoblu, will show you!
Developing software for the Internet of Things (IoT) comes with its own set of challenges. Security, privacy, and unified standards are a few key issues. In addition, each IoT product is comprised of at least three separate application components: the software embedded in the device, the backend big-data service, and the mobile application for the end user's controls. Each component is developed by a different team, using different technologies and practices, and deployed to a different stack/target - this makes the integration of these separate pipelines and the coordination of software upd...
Mobile messaging has been a popular communication channel for more than 20 years. Finnish engineer Matti Makkonen invented the idea for SMS (Short Message Service) in 1984, making his vision a reality on December 3, 1992 by sending the first message ("Happy Christmas") from a PC to a cell phone. Since then, the technology has evolved immensely, from both a technology standpoint, and in our everyday uses for it. Originally used for person-to-person (P2P) communication, i.e., Sally sends a text message to Betty – mobile messaging now offers tremendous value to businesses for customer and empl...
