One way to view a BIRT report on the web is to deploy the BIRT report viewer to an application server, such as Apache Tomcat, IBM WebSphere, JBoss, or BEA WebLogic. The BIRT Report Engine includes the BIRT report viewer as a web archive (.war) file and as a set of files and folders. Deploying the BIRT report viewer requires copying files from the BIRT Report Engine, which you must install separately from the BIRT Report Designer. This chapter provides information about deploying the BIRT report viewer using the WAR file or the set of files and folders.
