BTree Systems offers J2EE certification online training as well as classroom training and we also provide e-books for courses.
- 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.
- 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.
- BTree Systems offers the Java J2EE Course in Chennai, the instructors and subject matter experts are working professionals or subject matter experts with at least 10 years of experience in the information technology field. Candidates must demonstrate that they have the necessary abilities to operate a J2EE certification course by completing a real-world project at the end of the course.

Additional Information
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.
JEE vs Spring
- Java EE
- 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.
J2EE vs .NET
- Both.NET and J2EE are aimed at the massive enterprise application and Web services market. This fast comparison provides an overview of the benefits and drawbacks of both frameworks in several areas.
- Orientation
- J2EE is Java-centric and platform-independent, whereas.NET is Windows-centric and language-independent. This means that developers are limited to the Java language in the J2EE framework and Windows in the.NET framework.
- Distinctive Strategies
- J2EE is essentially a set of standards. In contrast,.NET Microsoft’s product strategy focused on the advancement of Visual Studio 6.0.
- Industry Involvement
- Sun has galvanized the whole industry behind its J2EE standard, particularly the leading software manufacturers that have modified the J2EE interface, including BEA, IBM, and Oracle. .NET, on the other hand, is built solely on Microsoft’s efforts to capture a share of the Web services market.
- Legacy Integration and Backwards Compatibility
- It is simple to connect J2EE programs to legacy code using adapters and Sun’s new Java Connector Architecture (JCA) specification. With its Host Integration Server 2000, .NET also provides legacy integration, but with limited connectivity to specific systems. In conclusion, experts believe that the J2EE legacy integration features are superior to those found in.NET, owing to the JCA market’s massive marketplace of adapters.
- Rapid Application Development
- Rapid application deployment functionalities are available in both.NET and J2EE. Some are more powerful in.NET than J2EE, and vice versa. J2EE provides state management services to make it easier for developers to write code and maintain the state. The actual advantage of ASP.NET, on the other hand, is that it is independent of a client device and allows user interfaces to be rendered to various user interfaces without changing code. Furthermore, Microsoft.NET provides Queued Components, business process management, and E-commerce capabilities that are often superior to analogous functionality available in J2EE.
- Pros and Cons of Single Vendor Solutions
- J2EE solutions from various vendors provide a wide range of tools, products, and applications. This does provide more and varied capability, but at a cost: J2EE tools are frequently incompatible due to portability issues. The reason for this is that they are not from a single provider and have not been thoroughly vetted. Larger J2EE suppliers provide robust solutions, but for low-level J2EE implementation, rigorous homework of mixing and matching is required for a full solution. On the other hand,.NET delivers a comprehensive solution of Microsoft tools and services, although it may lack some of the more advanced functionality available in J2EE solutions.
- Performance and Developer Empowerment
- J2EE is an excellent platform for educated and informed developers to take advantage of programming control over lower-level services like state management and caching. .NET architecture, on the other hand, lacks lower-level performance optimization services, prevents the introduction of faults into the system, and is thus better suited to developers who demand more guidance.
Benefits of the J2EE platform
- Because it provides developers with a variety of advantages, such as the following, the new J2EE 1.4 platform is the ideal option for creating web services and enterprise applications.
- Enhanced development productivity:
- This strategy boosts development efficiency by allowing well-designed generic components to be reused and mapped to the intended functionality of the application and service that is being developed.
- Support for emerging web service standards:
- The J2EE 1.4 platform offers complete support for web services and the WS-I Basic Profile, as well as for other new web service standards. Application exposure as web services is made possible thanks to this. More important, this guarantees that web services created on the J2EE 1.4 platform are interchangeable with web services created on any platform that complies with WS-I standards as well as transferable between J2EE implementations.
- Provides industry-standard:
- APIs for interacting with enterprise information systems, including the JDBC API, JMS, and J2EE Connector Architecture (EIS). Additionally, J2EE 1.4 is the ideal foundation for integrating current EIS by exposing their data to clients running on heterogeneous platforms due to the additional support for web services.
- Scalable to meet demand variation:
- J2EE containers offer techniques to facilitate scaling without requiring application developers to write code, as well as transaction support, database connections, and scalable life cycle management.
- Provides a flexible security model:
- A flexible security model is provided. It makes it simple for application developers to specify the method-level security requirements for components. Specific data operations would only be accessible to users with the necessary permissions.
Future Scope of J2EE
- The scope will 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.
