ColdFusion lets you create an EAR or WAR file that contains an entire application. This archive file contains the ColdFusion web application, settings for ColdFusion (such as data source definitions), the CFM pages used by your application (text or compiled Java), and optionally, the ColdFusion Administrator.
This feature lets you quickly create an archive file that a J2EE administrator can use to deploy your ColdFusion application.
J2EE archives are different from ColdFusion archives (CAR) files. For information on CAR files, see Create and deploy application archives. For details, see ColdFusion Archive overview.
Context root
Because the J2EE environment supports multiple, isolated web applications running in a server instance, each J2EE web application running in a server is rooted at a unique base URL, called a context root (or context path). The J2EE application server uses the initial portion of the URL (that is, the portion immediately following http://hostname) to determine which web application processes an incoming request.
For example, if you are running ColdFusion with a context root of cfmx, you display the ColdFusion Administrator using the URL http://hostname/cfmx/CFIDE/administrator/index.cfm.
Most J2EE application servers allow one application in each server instance to use / (forward slash) for the context root. The Remote Development Services (RDS) web application is not required if you use a context root of /.
