Assembling is an activity in which you package code components into "modules" that comply with the J2EE specification. You define configurations for the modules, in the form of XML documents known as deployment descriptors. See also Welcome to Assembly tools.
After you assemble modules into a main module called an application module or EAR file, you are ready to deploy the application module onto the application server.
The assembly process includes:
Gather the code artifacts that you want to package into one or more assembled modules. Code artifacts include these items that you have created and unit tested in your favorite integrated development environment:
The Assembly
Toolkit replaces the Application Assembly Tool. The Assembly Toolkit is available

. The
Assembly Toolkit consists of the J2EE Perspective of the WebSphere Studio
Application Developer product, including code generation capabilities.
Assemble EAR files from new or existing J2EE 1.3 application modules, including these archives:
Assembled modules need to be provided to the Deployer, who is usually the administrator.
