EAR file overview

An EAR file is a critical piece in deploying a service application to a production server.

An enterprise archive (EAR) file is a compressed file that contains the libraries, enterprise beans, and JAR files that the application requires for deployment.

You create a JAR file when you export your application modules from IBM® Integration Designer. Use this JAR file and any other artifact libraries or objects as input to the installation process. The serviceDeploy command creates an EAR file from the input files that contain the component descriptions and Java™ code that make up the application.
