Apache TomEE Integrations

The Java™ Programming Language is designed as a versatile, concurrent, and strongly typed object-oriented language that utilizes a class-based structure. Typically, it is translated into bytecode that adheres to the specifications laid out in the Java Virtual Machine Specification. In this language, developers write source code in standard text files that conclude with the .java suffix. These source files are subsequently transformed into .class files through the use of the javac compiler. Unlike native processor code, a .class file comprises bytecodes, which serve as the machine language understood by the Java Virtual Machine (Java VM). To execute an application, the java launcher tool creates an instance of the Java Virtual Machine, allowing the compiled bytecode to run seamlessly. This process exemplifies the efficiency and portability that Java offers across various computing environments.

Apache Geronimo is a collection of open-source initiatives aimed at delivering JavaEE/JakartaEE libraries along with Microprofile implementations. Our focus is on creating reusable Java EE components that are both widely utilized and actively maintained. The project supplies libraries that align with the specifications of Java EE and Jakarta EE, while also emphasizing the provision of OSGi bundle metadata. A key objective of the XBean project is to develop a server that operates in a plugin-based manner, similar to how Eclipse functions as a plugin-centric IDE. XBean will have the capability to identify, download, and install server plugins from a repository available on the Internet. Furthermore, it encompasses support for various IoC systems, the option to run without an IoC system, JMX functionality without the need for JMX code, lifecycle and class loader management, and robust integration with Spring. In addition to these features, Apache Geronimo also supports several Microprofile implementations. Moreover, the Apache Geronimo Arthur initiative aims to create a lightweight layer that operates on top of Oracle GraalVM, enhancing the project's versatility and performance. This makes Apache Geronimo a valuable resource for developers seeking comprehensive solutions in the Java ecosystem.

HtmlUnit serves as a "GUI-less browser for Java applications," designed to model HTML documents while providing an API for interactions with web pages, such as loading pages, submitting forms, and following links, which mirrors the functionality of a traditional web browser. Its JavaScript support is notably robust and continues to evolve, allowing it to effectively manage complex AJAX scenarios, and it can mimic various browsers like Chrome, Firefox, or Edge based on the chosen settings. While primarily aimed at testing or data extraction from websites, HtmlUnit is not a standalone unit testing framework; instead, it functions within larger testing frameworks like JUnit or TestNG to replicate browser behavior. This tool serves as the foundation for many open-source applications, including WebDriver, Arquillian Drone, and Serenity BDD, and is widely adopted by numerous projects focused on automated web testing, such as Apache Shiro, Apache Struts, and Quarkus. Its ability to operate without a graphical user interface makes it particularly valuable for developers seeking to automate browser interactions in a more efficient and resource-friendly manner.

Apache Tomcat® is an open-source software that serves as an implementation of various Jakarta specifications, including Jakarta Servlet, Jakarta Server Pages, Jakarta Expression Language, Jakarta WebSocket, Jakarta Annotations, and Jakarta Authentication, all integral to the Jakarta EE platform. This software is utilized by many large-scale web applications that are critical to the operations of various industries and organizations. Users and their experiences can be found on the PoweredBy wiki page, showcasing the extensive impact of this technology. The Apache Tomcat Project has proudly announced the launch of version 10.0.10, which adheres to the specifications outlined in the Jakarta EE 9 platform. With this release, developers gain enhanced features and improvements, further solidifying Tomcat's position as a leading choice for enterprise-level web applications.
