We offer J2EE to build/develop multitier web-based applications. The J2EE platform is consists of a set of services, application programming interfaces (APIs), and protocols.


J2EE application consist of four components:

  • Application clients components.

  • Servlet and JSP technology are web components.

  • Business components (JavaBeans).

  • Resource adapter components

What is difference between core Java and Java EE?


Basically Java can Categories into Three parts:

  • Java SE (Core Java or Java Core)

  • Java EE (Advance Java)

  • Java ME (Mobile Development with Java)


Java SE (Core Java) : Java SE is used for Developing Standalone application Or System Software that Run on System only. In The Java SE you can Learn the Basic of Java Like: Inheritance, Polymorphism, Strings etc.Java is object-oriented programming language and Java is very vast technology stack and according to need and industry java has different edition like JSE(Java Standard Edition),J2EE(Java Enterprise Edition),Java ME (Mobile Development with Java). This java edition is used to write standalone command line programs. When combined with tooling libs like Swing you can build GUI based desktop application.

so perform core programming operation core Java or JSE.


Java EE (Advance Java) : Java EE is used for developing Web Applications that Run with the help of Web Browser. In Java EE you can Learn the Advance topics Like: Servlet, Java Server pages(JSP), Enterprise Java Beans(EJB) etc. J2EE is a set of specifications which targets the enterprise technologies like JMS, WS, Servlets, JSP, EJB's etc. Most of these specification are implemented using Java. Using J2EE technology stack you can write complex business application if we say more details then it's mostly useful if the applications you're developing have to be multi-tiered, fault-tolerant and/or distributed, running on application servers.

Java J2EE Enterprise Application Model

Java ME (Mobile Development with Java) : Java ME is used for Developing Mobile Application that run on the Mobile Phones. In The Java ME basically you Learn about Android App Development.



Keeping us on top of that foundation, we are creating and providing the best solutions and almost every type of coding solutions to help developers rapidly build fully functional web applications. The entire Codersarts platform is built with developers in mind and provides the tools they need to create incredible web applications.

So, what exactly is the difference then between a coding solutions and a development services ?


Other Java Service

  • write a java console or gui program for you

  • do database projects and jdbc

  • make restful api in java spring boot

  • java jsf desktop app developer

  • develop spring web service java

  • Programming assignment in python, c, csharp, java

  • Develop sql database and sql queries projects


Reason to select Java J2EE


Flexible User Interaction

The J2EE platform provides choices for graphical user interfaces across a company's intranet or on the World Wide Web. Clients can run on desktops, laptops, PDAs, cell phones, and other devices. Pure client-side user interfaces can use standard HTML and Java applets. Support for simple HTML means quicker prototypes, and support for a broader range of clients. Additionally, the J2EE platform supports automatic download of the Java Plug-in to add applet support where it's lacking. The J2EE platform also supports stand-alone Java application clients.

For server-side generation of dynamic content, the J2EE platform supports two types of web component technologies: Java Servlets and JavaServer Pages (JSP). Java Servlets enable developers to easily implement server-side behaviors that take full advantage of the power of the rich Java API. JavaServer Pages technology combines the ubiquity of HTML with the power of server-side dynamic content generation. The JSP 2.0 specification supports static templates, simplified access to Java objects, and easy extensibility.


Hiding Complexity, Enhancing Portability

The J2EE application model divides enterprise applications into three fundamental parts: components, containers, and connectors. Components are the key focus of application developers, while system vendors implement containers and connectors to conceal complexity and promote portability.

Containers intercede between clients and components, providing services transparently to both, including transaction support and resource pooling. Container mediation allows many component behaviors to be specified at deployment time, rather than in program code.

Connectors sit beneath the J2EE platform, defining a portable service API that communicates with existing enterprise vendor offerings. Connectors promote flexibility by enabling a variety of implementations of specific services. In particular, connectors implementing pluggable messaging contracts enable bidirectional communication between J2EE components and enterprise systems.


Web Services Interoperability

The Java 2 Platform, Enterprise Edition version 1.4 is the most complete Web services platform ever. The platform features Web services support through the new JAX-RPC 1.1 API, which provides service endpoints based on servlets and enterprise beans. JAX-RPC 1.1 provides interoperability with Web services based on the WSDL and SOAP protocols. The J2EE 1.4 platform also supports the Web Services for J2EE specification, which defines deployment requirements for Web services and utilizes the JAX-RPC programming model. In addition to numerous Web services APIs, the J2EE 1.4 platform also features support for the WS-I Basic Profile 1.0. This means that in addition to platform independence and complete Web services support, the J2EE 1.4 platform offers platform Web services interoperability.


Expediting Development and Deployment

Based on these flexible component configurations, the J2EE application model means quicker development, easier customization and greater ability to deploy powerful enterprise applications. And, because it's based on the Java programming language, this model enables all J2EE applications to achieve all the benefits of Java technology: scalability, portability, and programming ease.


Our view is that a coding solutions is primarily focussed on building solid foundation while learning a new skills or programming Like understanding concept and coding workflow, whereas a development services is all about interacting with development team or helping business. coding solutions tend to be more short time or one time solution while development services are for long term connection to grow business.
