What is J2EE?
J2EE is a Java Enterprise Edition, a standalone Java environment used by software or system developers to construct and deliver a web-based application or website. It is a well-known platform that makes use of Java because of the advantages of its dependability, security features, portability between platforms, ease of implementation, ongoing updating to meet the most recent and popular technological needs, etc.
Why do we use J2EE?
The J2EE platform offers options for graphical user interfaces on the Internet or an organization’s intranet. Desktops, laptops, PDAs, mobile phones, and other devices can all run clients. Standard HTML and Java applets can be used for pure client-side user interfaces. A wider range of customers can be supported and prototypes can be created more quickly with support for plain HTML. The J2EE framework also allows for the automatic download of the Java Plug-in to supplement any areas where applet functionality is lacking. Additionally, the J2EE platform allows clients to standalone Java applications.
The J2EE platform supports Java Servlets and Java Server Pages as two types of web component technologies for server-side production of dynamic content (JSP). Developers may quickly design server-side actions that fully utilize the strength of the robust Java API thanks to Java Servlets. Java Server Pages technology combines the popularity of HTML and the potency of server-side dynamic content generation. Static templates, streamlined access to Java objects, and simple extensibility are supported by the JSP 2.0 specification.

Java vs J2EE
Application of Java and J2EE: Java is reliable and platform-independent; thus the code can be executed on any platform that supports a Java Virtual Machine (JVM). It is useful for websites, servers, mobile phones, embedded systems, etc. because it just needs to be developed once and executes anywhere thanks to the bytecode’s ability to run on different operating systems. On the other side, J2EE offers a platform-neutral environment for building substantial corporate applications.
J2EE and Java components: Java Virtual Machine (JVM), Java Development Kit (JDK), and Java Runtime Environment are the three primary components of the Java language (JRE). Each element complements the others to make software development easier. On the other side, J2EE includes Enterprise JavaBeans, Servlets, and Java Server Pages (JSPs) (EJBs) along with Java Database Connectivity (JDBC).
A platform for Java and J2EE: It is a high-level, class-based programming language that is frequently employed for creating and distributing information on the internet. However, it is a condensed form of C++ created to function on any platform that complies with the JVM, regardless of the architecture. One of the fundamental components of Java used to create server applications like websites and web applications is J2EE.
Terminology of Java and J2EE: Sun Microsystems first applied the moniker to the Java Standard Edition (Java SE). It is a popular programming language with fewer implementation dependencies that borrows a large portion of its grammar from C and C++. Oracle Corporation owns the J2EE collection of Java APIs, which are used to create server-side enterprise applications.
J2EE vs Spring
J2EE
JEE, also referred to as Jakarta Enterprise Edition (JEE), is an Oracle Java platform that was formerly known as Java Platform, Enterprise Edition (Java EE). It provides a set of specifications that add enterprise functionality for application development, like distributed computing, web services, and Java microservices, to the characteristics supplied by Java Standard Edition (SE), increasing its feature set.
Enterprise Java Beans (EJBs), Java Server Pages (JSP), and Java Database Connectivity (JDBC) are the three main components of Java EE. Microservices or application servers, which manage all the essentials including transactions, security, scalability, concurrency, and component management, are used to execute Java EE applications. These are the things that an application must function properly and without a hitch.
Spring
Spring is a Java EE application development framework. It is an open-source Java platform that offers assistance in creating powerful and expansive Java applications. Additionally, it provides a tonne of extensions that may be utilized to construct other kinds of expansive applications on top of the Java EE framework.
With the help of this compact framework, programmers may create enterprise-class apps utilizing POJOs, or Plain Old Java Objects. Despite not having a unique programming model, Java developers have grown to love the Spring framework as a supplement to the Java platform. There is a sizable Java developer community that is working and contributing to expanding the functionality supplied by the Spring framework and adding new extensions.
The key difference between Java EE vs Spring: The comparison of a few very specific characteristics is typically the basis of discussions between Java EE and Spring.
Different architectures
Java EE is based on a three-tier architecture. The first is the presentation tier, which houses the user interface and is concerned with providing a smooth and reliable experience. The second tier is the application layer, which houses the application’s primary business logic, and the third tier is the data layer, which includes the database and other data requirements.
Contrarily, Spring is built upon a tiered architecture that consists of several components. Each module offers unique functionalities to the applications, and they are all built on top of their core containers.
Supported languages: High-level object-oriented programming languages are used in Java EE. In Java EE, which verifies all of a programming language’s listed features, Java is used. Spring has no set programming model. Java and Kotlin are also options for developers in Spring.
Structures: While Spring supports a range of application structures, including Microservices, the cloud, serverless event drivers, web apps, etc., Java EE can only be used to construct web-based structures.
Performance and Speed: When comparing Java EE to Spring, speed is a common topic of discussion. Spring is slightly slower than Java EE in terms of performance and usability, making Java EE the obvious victor in terms of speed.
Cost of Projects: Project costs are one of the main distinctions between Java EE and Spring. Unlike Spring, which has an open-source license, Java EE or Jakarta EE has an Oracle-based license. Use of it is free.
Standardization: Sun/Oracle created the Java EE standard and specification. Object-Relational Mapping, Security, Web Applications, database availability, and exchanges are all included in Java EE.
Future Scope of J2EE
The scope never end for a Java/j2EE developer. For a particular level of knowledge necessary in the Java/J2EE industry, there are various options available in the present market. Java/J2EE professionals are always welcome to introduce any popular tool that is currently on the market. The Java/J2EE field currently has the most businesses or job openings in the IT industry. Therefore, the knowledge of those who work in this particular profession is always valuable in all circumstances.
J2EE developer salary package
J2EE developer salary package for freshers: Java J2ee Developers in India often get an average beginning salary of 2.0 Lakhs per year (16.7k monthly). To be a Java J2ee Developer, you must have at least one year of experience.
J2EE developer salary package for experience: An Entry Level Java J2ee Developer makes an average income of 3.4 Lakhs annually with less than three years of experience. A Java J2ee Developer in the middle of their career with 4 to 9 years of experience makes an average pay of 8.2 lakhs per year, while a Java J2ee Developer with 10 to 20 years of experience makes an average compensation of 16.7 lakhs per year.
