To create a new resource adapter rar file:
The New Resource Adapter Wizard is displayed. The Resource Adapter Wizard helps you create a resource adapter, provide an EAR, and generate a deployment descriptor from the information that you enter into the first two screens of the Wizard. The Wizard bundles a resource adapter into a Resource Adapter .rar file, hereafter called a RAR file.
Once your .rar file is created, you will see it added to the application in the tree view on the left side of Deployment Tool.
Already created EARs and Resource Adapters may be added to an application by using the EAR button in the second group of buttons on the tool bar of the primary window of Deployment Tool. Updating and deployment of the application are accomplished using the third set of buttons on the tool bar. Finally, the correctness of the components and files of the application may be checked before deployment by the Verifier Tool.
