Java application servers

Application servers are programs running on some server-side backend – either a dedicated server or a virtual machine running on cloud resources – that run software services for Web apps. Java application servers meet a set of requirements set by the current version of the Java Platform, Enterprise Edition (Java EE, previously J2EE).

Examples of common Java application servers include Apache Tomcat, Eclipse Jetty, Caucho Resin, and IBM WebSphere, among others.
