In addition to running as a standalone server and as a service, JReport Enterprise Server can also run as a servlet inside a Java application server. Since JReport Enterprise Server is implemented using servlets and JSPs, it can work with any servlet-enabled web application server by assembling and deploying JReport Enterprise Server as a Web Application Archive (WAR) or Enterprise Application Archive (EAR).
There is a separate chapter about integration with different application servers - Integrating JReport Enterprise Server with a Java Application Server. It provides a general method for creating the deployable archive and detailed procedures for deploying the archive into some popular application servers.
