Hire a J2EE Developer

Java is one of the most comprehensive programming languages in use today. With around 8 million developers who use Java globally, it is also one of the most popular. J2EE (Java 2 Platform, Enterprise Edition) implements the Java programming language, including standard APIs for writing and deploying server-side applications.

Common Java Use Cases

Java makes it easier for developers to build high-performance Java apps, and it also enables the creation of reusable and modular code applications in a distributed computing environment.

Below are some of the most common cases J2EE engineers rely on Java.

Mobile Applications

J2ME is a cross-platform framework for building mobile apps for Java-supported smartphones and feature phones. One of the most popular mobile operating systems, Android SDK, is Java-based, and Netflix and Uber are two other well-known examples of this use case.

Web Applications

Companies with large web applications, such as Amazon, employ the web application features of Java. J2EE engineers can easily and quickly create fast and secure websites following J2EE standards.

Enterprise Applications

Java makes robust, secure, and highly scalable applications. Because of this reason, as well as Java’s rich features and fast performance, it is the first choice for enterprise programs. Java Enterprise Edition (Java EE) is a platform for scripting and operating enterprise software, network tools, and web services.

Oracle says 97% of enterprise computers use Java. Most enterprise apps are written in Java due to their excellent performance and speed. It’sIt’s especially prevalent in Enterprise Resource Planning (ERP) and Customer Resource Planning (CRM) systems.

Big Data Technology

This tool involves carefully examining and extracting information from complicated data sets. Hadoop is a popular Java-based Big data framework. Java has many features that assist with Big data analysis, including automatic garbage collection, memory distribution, and stack provisioning. Hadoop, Apache HBase, ElasticSearch, and Accumulo.

Qualifications of a J2EE Developer

Do you require a junior, mid-level, or senior software engineer? This is a question you are probably asking yourself if you are looking to hire a J2EE developer. Understanding what you need from a developer will help you write a job description, interview qualified individuals, and recruit the ideal J2EE engineer. To help you better understand this, let’s compare seniority and its influence to help you grasp juniors, mids, and senior developers:

Junior Level Developers

Junior developers typically have 1-3 years of experience in development. They should be fluent in one or two languages/frameworks and have dabbled in a couple of others. They should understand how software interacts with and is dependent on hardware and an understanding of fundamental programming principles. These developers are typically given entry-level positions that require lighter tasks with supervision.

Mid-Level Developers

A mid-level engineer should have at least 3-5 years of experience or a bachelor’s degree in computer science and one or two years of experience. They should have mastered two to three languages/frameworks during this phase of their career.
These types of J2EE engineers have general knowledge of industry best practices. They typically can communicate directly with business people occasionally to clarify minor details related to the assigned task. Also, they can write basic unit tests and debug code.

In a J2EE engineer career, a mid-level developer should have full stack experience (backend, frontend, and databases). These developers are also known to take on challenging tasks without much supervision.

Senior Level Developers

A senior engineer should have at least five years of experience and be fluent in at least one modern language. If they don’t have a grasp of any languages, they should at least be able to grasp new concepts quickly.

Developers at this level should also be excellent communicators, technical project managers, and architects. They should possess the ability to convert business processes into programming code, and they should be able to create complex tests and have outstanding debugging skills.

Senior-level engineers generally take on leadership positions or project management roles and are considered experts in their respective fields.

These developers are familiar with effective industry best practices and processes for Java development.

Benefits of Hiring a J2EE Developer for the J2EE Platform

Simplicity

J2EE provides component-based development. J2EE is portable because it’s based on the Java programming language and the J2SE platform. This model works on J2EE servers. Also, J2EE supports heterogeneous environments. J2EE apps don’t require a specific OS, middleware, or hardware. In a heterogeneous computing environment, a well-designed J2EE-based program only can be deployed once.

The J2EE standard allows clients to acquire third-party J2EE-compatible components and deploy them in a heterogeneous environment, saving them the cost of building the full application themselves.

A More Streamlined Development Process

Due to component technology, application development can be separated and developed simultaneously to increase development efficiency.

For example, graphic designers produce JSP templates, experts do business logic, Java programmers create JSP pages and EJBs, and other team members assemble and deliver applications.

Many of these tasks can be done simultaneously to speed up application development.

Portability

In addition to the inherent portability of the Java language, the EJB design provides standardized APIs between the Bean and its container, allowing developers to migrate the Bean from one operating environment to another without rewriting its source code.

Low Maintenance

Components simplify application maintenance. New functionalities can be introduced by modifying individual program components.

Skills to Look for in a J2EE Engineer

If you are wondering what skills you should be looking for when hiring a J2EE developer, it’s important to note that it may vary – from organization to organization.

Below are some baseline skills that are typically helpful for a J2EE developer to possess:

• Object-Oriented Programming (OOP) and design pattern knowledge in Java
• Abstract class and serialization expertise
• Excellent knowledge of Java build tools such as Maven and Gradle.
• Knowledge of JQuery, Ajax, JSON, CSS, and HTML
• Knowledge of Java EE components such as Servlets, Java Beans, and Java Server Pages
• Extensive knowledge of Java Application Containers such as JBoss and Jetty
• Experience with big data technologies such as Hadoop and Spark
• An understanding of GitHub version control
• An understanding of relational databases, SQL, and ORM technologies
