How Java Technologies help in Modernization of Enterprise Applications?

Almost all big editions rely on the J2EE for computing. J2EE stands for Java 2 Platform, Enterprise Edition. Java development India helps various enterprises in developing software applications.

Java also helps in reducing the costs related to programming as well as training costs. This is mainly because Java helps in the creating standardized modules that are reusable by the developers.

Additionally, java also helps to create a software that has multiple tiers, all to help the programming handle different aspects properly and without interference.

The alternative to java did not work well as a group even though individually they were excellent. Together, they created redundant information that only ended up confusing the users. Moreover, whenever there were any changes regarding an information, it had to be manually included, which was neither modern nor favorable to the employees.

This often resulted in poor consistency. Java on the other hand is totally automatic. Its architecture has four integration methods. They are:

  • Data level Integration
  • User interface (UI) level Integration
  • Application level Integration
  • Method Integration

With the help of data level integration, a programmer can integrate backend data store that the integrated applications can use for collection of information. This integration can be either push based or pull based.

With push based data level integration, one application makes SQL calls with the help of database links on the database tables on other applications. Push based data level integration helps in pushing the data into the database of another application.

In contrast, the pull based data level integration helps utilize the triggers and polling. Triggers help to capture the changes in data and write the information they identify on interface tables.
User level integration mixes the integration logic with the user interface code. UI level is based on scripting or is proxy based.

With this level integration a programmer cannot easily or even directly access the database. Their mainframes do not have access to the friendly data stores and lacks contact with public APIs.

Application level integration is the best way for the integration of applications. It uses the frameworks of the integration applications and the APIs. It lets you use the logic of business for the preservation of data integrity. It is transparent about its working as well and is overall a great choice.

Method level integration is not as well known or well used as the other application level integrations. It collects common operations on multiple APS and merges them into a single application for the integration applications.

Aside from the integration for simplification and storage of information, the Java application also has general APIs that are a mixture of Techno gym for the extension of the basic functions of the application. They are:

  • javax.servlet: With the help of this servlet, defining a range of APIs for the addressing of HTTP requests is easier and simplified. This servlet includes the specifications of Java Server Pages.
  • javax.websocket: This particular specification helps in defining the APIs that are linked with WebSocket connections.
  • javax.faces: Java Server Faces of JSF API has its roots in the javax.faces. This component is mainly used for the developing o user interfaces with the help of several other components.
  • javax.faces.Component: This is one of the core packages that is component oriented and is a part of Java Server Faces API. It comes with a UML diagram of the component hierarchy.
  • javax.enterprise.inject: This API is used for the injection of annotations that defines beans, stereotype, built in qualifiers, classes and other interfaces that belong to the Context and Dependency Injection (CDI) APIs.
  • javax.el: For defining classes and user interfaces for the Expression language of Java EE, this is the package that is used. Expression language is designed specifically for the addressing specific needs of developing web applications.
  • javax.enterprise.context: This package declares setting annotations that are current under Context and Dependency Injections (CDI) API.
  • javax.ejb: JavaBean is an enterprise that contains lightweight APIs. Lightweight APIs is a set of reusable code for the communication of other software applications. Some of the major functions that are supported for the framework include transactions that use JTA, concurrency control, access control, remote procedure calls such as RMI or RMI-IIOP and dependency injections for business objects.

Along with APIs Java EE Technology has tiered applications that are used to separate basic functionalities into isolated areas. There are different tiers such as the client tier, the middle tier and the data tiers. Collectively they are known as enterprise information system tier.

Client tier controls the client program that sends requests to the middle tier. The business functions of the middle tier deal with the client requests and processes application data. It also stores data in the data store that is present in the data tier.

The java development India is reaching new height with every new innovation because it is not only easy to use with the various APIs, but also provides a variety of ways for integration into the system. Selecting the best method of application for you company therefore shouldn’t be difficult.
