Hire Java J2EE developers
Java 2 Platform, Enterprise Edition (Java J2EE) is a tool or platform for developing, building, and deploying web-based, multi-tiered enterprise applications on the web. It is a platform-independent tool, i.e., it can be used on any platform may it be the web or a desktop. It is developed using the Java language. But it also supports pure HTML applications. These HTML applications rely on Java servers for their work. This platform provides its users (developers) with APIs, protocols, and services that help developers develop web-based applications. These provided components are essential for the successful deployment of any application. One of the layers provided by Java J2EE is Enterprise JavaBeans (EJBs). The EJBs store the logic of Java J2EE. The server of EJB provides the developers with functions like concurrency, memory management, security, threading, etc. Java J2EE is a very transparent platform for developers. Most Java J2EE applications use Java Database Connectivity (JDBC) as an interface for their databases. It is the standard interface for Java-based databases. The Java servlet API eliminates the need for a graphical user interface (GUI). The Java servlet API is a powerful tool that enhances the consistency of the applications for the developers.
Learn more about Java J2EE
Java J2EE provides a simplified approach than most platforms in the market for the development of internet and/or intranet applications. The applications developed using Java J2EE are highly scalable and highly available. The most amazing thing about using the Java J2EE platform for application development comes with in-built life cycle management, transaction management and resource pooling facilities. The applications designed and developed using Java J2EE can communicate effectively and transparently using XML, SSL, IIOP, RMI, HTTP, HTML, etc. The components of Java J2EE are reusable. That is why the developers and Information Technology (IT) organizations prefer to use Java J2EE. Java J2EE does not force the developers to use all the components in the application development from the Java J2EE package. The developers are free to use a combination of standard, commercially available components and custom components of their creation. Due to this free, malleable and flexible nature of Java J2EE, applications can be done faster and with better quality. The portability and maintainability of the development applications can also be enhanced. This leads to greater returns, best use of resources and increased productivity of the developers.

Important features of Java J2EE
1. Java Database Connectivity (JDBC) drivers
Any application designed using Java J2EE can access or connect to a database through a Java Database Connectivity (JDBC) driver. Java Database Connectivity has two extensions viz. JDBC 3.0 API and JDBC 2.0 can be accessed through the Java Database Connectivity (JDBC) drive
2. Transaction Service
The transaction service of Java J2EE is used for ensuring that data has been updated in the desired manner to maintain the integrity of the data. The transaction service has transactional resource managers that enable the JDBC API, connector modules and JMS API to do the needful.
3. Java Naming and Directory Interface (JNDI) API
The Java Naming and Directory Interface (JNDI) API is a platform to make Java J2EE resources available. It allows its users to look up distributed resources, services and EJB components for developing applications.
4.Java Message Service (JMS) API
Java Message Service (JMS) API is a feature of Java J2EE that allows the users to send, receive, create and read messages in the application. This feature makes available queues, message destinations and topics to the application users.
5. Java Mail API
Java Mail API is a very similar feature to the Java Message Service (JMS) API. This feature, instead of messages, allows the creation, receipt and reading of mail messages. This feature is made available through the JNDI API.
