Java Technologies List

We don't have to install any additional software on the computers of our clients or other computers to create a web app. They can use their browsers as client clients to run the application. Businesses can update and maintain their web applications without having to deal with the hassle of maintaining and updating the application. These web applications can be used for online retail, webmail and online banking. A web application can be accessed by millions of people simultaneously, which makes it more popular. Businesses prefer Java development tools because of this.

Let's now look at the Java technologies List we can use for creating web applications. To use Java, you must ensure that these technologies have been installed on your system. The server must also have a container or web server built in that can detect and execute the classes you create.

1. Java Servlet API Java Servlet, Java's first ever server-side web technology, allows you to create HTTP-specific classes. The servlet class increases the power and capabilities of the servers and hosts an application. These applications can be accessed via the request-response editor model.

A servlet can answer any request. However, its main purpose is to extend web-based applications. You can use servlets, for example, to access data from an online program or to extend it to display on the screen or to an HTML page. You can also use the servlet for writing data to a file or database. The servlet runs on the server-side without any HTML or application GUI.

2. Java Server Pages Technology Java Server Pages (JSP), a popular technology for developers, is a fast and easy way to enhance dynamic web content. This allows for the development of standalone web applications and web platforms quickly. You can also add a small snippet of code to the app's text, making JSP more accessible to developers. JSP pages can also be text-based documents and include two types text:

Static data can be expressed using any text format including HTML, HTML or WML. JSP Technology completely determines dynamic content creation for a web page.

The packages used for JSP page building are javax.servlet.jsp, javax.el, javax.servlet.jsp.tagexta, and javax.servlet.jsp.el. You will need to import these packages. It is very simple to create a web app with JSP code and extensions.

A single caption can be used to create a JSP technology page. These captions are then placed into the header.html file which describes site navigation. You can make changes to buttons and links by editing one file. The site will automatically redirect to that file.

The Java program development company asserts that JSP is the best technology to create powerful web contents like forms, surveys and more.

JavaServer Pages Standard Tag Library, (JSTL), integrates core functionality that is common to many JSP-based apps. You don't need to use tags from different vendors. Instead, you can use one set of tags. This configuration makes it possible to run your applications on any JSP container with JSTL support. It also increases the likelihood that the tag implementation will improve.

JSTL contains duplicate tags and conditional tag to control flow controls. XML document deciphering and global tags are also available. Website access tags with SQL are also available. Commonly used function tags can also be found in JSTL. The packages you can access using JSTL are javax.servlet.jsp.jstl.core, javax.servlet.jsp.jstl.fmt, javax.servlet.jsp.jstl.sql, and javax.servlet.jsp.jstl. tlv.

3. JavaServer faces Technology JavaServer Faces Technology is a UI framework that lets you create web applications. JavaServer Faces Technology's GUI component framework renders components in various mark-up languages. RenderKit is available for creating HTML markups. This functionality is possible with Java APIs as well as XML configuration files. Sun Java Studio Creator IDE's GUI drag-and-drop tools allow you to use technology without having to write or understand any code.

4. JDBC API Java Database Connectivity API (JDBC), is very popular. It allows you to request SQL commands within Java applications. There are no restrictions on JDBC API requests. You can use JSP pages, servlets, and enterprise beans to request it. JDBC has two components. One is an application-level interface, and the other is a service provider interface. The application-level interface allows you to access the database via application components. The server provider integrates JDBC driver into Java enterprise platform.

5. Java Message Service API It is obvious that messages are important, regardless of whether they are between people or software parts. Throughout the software program, the messaging system is peer-to-peer-centric. The messaging client sends a message and then receives messages from other clients.

Each client is connected to a message agent who assists with creating, sending, receiving and reading messages. Java Messaging Service API, a Java technology platform, solves the problem and accomplishes its purpose. Enterprise messaging is a flexible and reliable method of data exchange across the company. The JMS API extends these capabilities and provides a framework for the development of portable messaging apps in Java Programming. It is up to you how you use the JMS. It can be used to provide innovative monitoring.

6. Java API for XML Processing XML (Extensible Markup Language), processing is an important part of Java web development. Java API for XML Processing, JAXP supports it using the Simple API to XML (SAX), the Document Object Model and XSLT API. JAXP allows for application analysis and conversion of XML files without the need to use XML processing.

Namespace support allows you to use conflicting word schemes in your application. It's highly configurable, supports W3C schema, and allows you to use XML/XSL-compliant processors in the application.

7. Java Naming and Directory Interface, JNDI It provides both naming and directory features. This allows apps to access multiple directory services and naming services, as well as allowing them to be named. It also provides common directory operations, such as attribute association and object search. The JNDI allows applications to interact with legacy systems and applications by storing and retrieving various named Java technology objects. Naming services are provided to enterprise beans, web components and application clients.

Developers can also customize components by using a naming environment, without having to modify or access the source code.

8. Java Persistence API Java Persistence API (JPA), which uses object-relational mapping, links an object-oriented model with a database. Java Persistence makes it easy to manage relational data in Java apps. This allows you to retrieve or store large amounts of data on a regular basis.

There are no need to use proprietary frameworks or codes. JPA provides a simple way to connect to the site via an object relational approach. JPA is a collection effective classes and methods that will connect you to a database.

9. JavaMail API and JavaBeans Activation Framework JavaMail API can be used by web applications to send email notifications. The API is made up of two parts. One is the interface that program components use to send emails and the other is the interface used by service providers. Some email protocols are used by service providers, including SMTP (Simple Mail Transfer Protocol). The JavaMail API package includes several service providers, while some of them can be purchased separately. Java EE Forum includes a JavaMail extension that allows you to send email from certain parts of the application.

You can integrate with JavaMail to access the JavaBeans Activation Framework API. This API offers standard services to identify the type of wrong data, compile access, locate the services it provides, and create the appropriate component based upon the creation of a JavaBeans (JavaBeans) component to accomplish those tasks.
