Java Application Server
A Java Application Server is a server platform that provides a runtime environment for deploying, managing, and executing Java-based applications, particularly Java EE (Enterprise Edition) or Jakarta EE applications. It handles critical services such as transaction management, security, database connectivity, and web services, allowing developers to focus on business logic rather than infrastructure. Common examples include Apache Tomcat, WildFly, and IBM WebSphere.
Developers should use a Java Application Server when building enterprise-level applications that require robust scalability, security, and integration with other systems, such as in banking, e-commerce, or large-scale web services. It is essential for deploying Java EE/Jakarta EE applications that rely on standardized APIs for components like servlets, JSPs, EJBs, and JMS, ensuring portability and compliance with industry standards.
