Java EE is one of the over 30 different Java APIs. In a short while, that number will most likely grow to or surpass 50. That will probably happen with the expected launch of Java EE8. Without them, it would be difficult for developers to create the applications we need for both mobile and web. However, it relies on several core technologies to function expectedly. Let’s delve into this Java Tutorial, which will examine the technologies that ensure efficient use of Java EE.
HTTP Client Technologies
As a developer, you will interact with HTTP-based clients on more occasions than you care to imagine. For this reason, you must be ready for all that and more. Java EE helps in preparing you through its HTTP Client Technologies. In this regard, it comes with several other tools that developers will find quite useful in their trade. Some of these tools include Java API for WebSocket Programming. Apart from Java Example, others are the following:
- API for JSON Processing
- JSF and Servlet APIs
- JSP Standard Tag Library
Database & Resource Access Technologies
As all developers know, interactions with external and backend systems are impossible to ignore. For this reason, Java EE would be an excellent choice for developers. Mostly, the main benefit of using Java EE in this regard would be the chance it provides to access its data and resource access technologies. More specifically, you would be able to take advantage of its JavaMail. Other than that, you would also benefit from using:
- A typical connector architecture
- Java Message Service, or JMS API
- Java Transaction API
REST & Web Service Technologies
The best Java developers are capable of creating different resources using Representational State Transfer (REST). More than that, they are also able to use the same technology for deleting, retrieving, and maintaining the same resources. In this regard, they would find Java EE an ideal tool because of the range of REST and web service technologies that it has to offer. Through these technologies, a developer’s task and life would be much easier.
Java EE Security & Container Management
Java Containers fall into different categories. These include Applet Container, Application Client Container, Enterprise JavaBeans (EJB), and Web Container. For developers, the main issue with these containers is management. Fortunately, Java EE has entered the fray to make their work a lot easier. Through it, developers are able to manage the containers efficiently. Furthermore, this technology makes the Java Authorization Contract more accessible to the developers.
