A web app assists customers to communicate with the server and see the information. Java plays an important role in developing large web apps because they can communicate with a bigger number of systems. Services such as back-end services, database connectivity, and peer-web services can be reached using java web development.
There are numerous platforms present in Java for web development. Keeping this scenario in mind, we are presenting to you the list of java technologies that are used to develop perfect java web apps.
Servlet API
The java. servlet comes with various interfaces like servlet config, filter chain, filter, and servlet, etc. it plays a very important role in increasing the capability of the servers that are utilized to host apps. The web apps created through servlet in Java follow the request-response framework. A servlet has a lifecycle beginning from being prepared to get collected via garbage collector. Servlets offer an independent platform service to its consumers for web development. Other than creating dynamic web pages, servlets also assist in various procedures like:
- Gathering input through a third-party source
- Data presentation from database
- Web page forms
The servlets are java programs that perform on a web app and transfer the request coming from the customers to the servers. The servlets assist in the client’s request processing. These results are provided after database communication.
JSP
JSP technology is utilized by developers to develop web content quickly. This is server and platform-independent. Rather than having a single Common Gateway Interface (CGI) file for implanting active elements in HTML pages, you can utilize JSP technology. This has complete access to the whole Java APIs family.
Web development can be done simply with the assistance of special JSP tags. This assists in embedding Java code in HTML pages. A JSP page includes static data that is written in XML, WML, and HTML. These JSP technology elements help in governing the dynamic movement of web content. You can add extracts from servlet code directly in a text-based document. This is done via JSP technology. It is a prominent technology offered by Java EE. This helps the developers to create difficult dynamic web pages very quickly.
JDBC API
This enables the client to link the database through apps developed via JDBC API. They play an important role in accessing, saving, deleting, and updating data. JDBC is known for reading all the databases and automatically develops an XML format of information from the database.
Both asynchronous and synchronous processing can be done through JDBC API. The processed outcomes are highlighted simply to the customers through JDBC. It supports various SQL queries and statements that can be utilized to link to the database.
Java Persistence API
Java Persistence API (JPA) utilizes object-relational plotting to link an object-oriented framework to the database. Relational data in Java apps can be simply managed through java persistence. It assists in the retrieval and storage of a huge sum of data from the database obstinately. You are not required to utilize so many codes and proprietary models to interact with the database. JPA will offer you simple means of communication with the database utilizing an object-rational method. JPA is an assortment of efficient methods and classes that can join you in the database.
JavaServer Faces Technology
JavaServer Faces Technology is a popular user interface model that is required to develop web-based interfaces. JSF offers a simple framework for providing components in different markup and scripting languages. The user interface thingamajigs’ are joined with server-side event handlers and data sources. Current standard user interface components can be utilized again and extended in the construction of interfaces through JSF. JSF plays an imperative role in decreasing the efforts in developing and sustaining web apps.
