nterprise Ar chive When it comes to deploying a Forms application you need to get all your FMX, PLL and MMX files and make sure you put them on the correct place on the application server before you can run the application. Wouldn't it be great if you could zip up all of these files in the correct structure and just "drop" them onto your new application server? Well J2EE already gives you that. The EAR file allows the J2EE application to be bundled and deployed as a single file.
(Enterprise Archive) A file format used for deploying a J2EE application. An.ear (Enterprise Archive) file consists of one or more J2EE modules and a deployment descriptor. Within the .ear file, components are grouped into separate module types--JSP pages, servlets, and HTML pages are grouped into web archive files (.war files) while enterprise beans are grouped into EJB modules (EJB .jar files). See also EJB, J2EE application, JSP, WAR.
