A resource adapter archive (RAR file) is a Java archive (JAR file) used to package a resource adapter for the J2EE Connector Architecture (JCA) for WebSphere Application Server.
Before you begin
This article assumes that you have created and unit tested a resource adapter RAR file that you want to assemble in an enterprise application and deploy onto an application server.Why and when to perform this task
In the Application Server Toolkit (AST) and Rational Web Developer assembly tools, RAR files are called connectors and assembled resource adapters are called connector modules.A connector is a J2EE component that provides access to Enterprise Information Systems (EIS), and must comply with the J2EE Connector architecture (JCA). An Enterprise Information System (EIS) is a set of related classes that lets an application access a resource such as data, or an application on a remote server, often called a resource adapter.
This article describes how to create a connector module using an assembly tool.
Steps for this task
Result
A new connector project is created. Files for the connector project are shown in the Project Explorer view under Enterprise Applications and Connector Projects.What to do next
After creating a connector project, you can edit the connector deployment descriptor if default properties are not sufficient. In the Connector Deployment Descriptor editor, you can view and edit source code.For more information, see the online help for the assembly tool. Similar information is in the Application Server Toolkit information center available with this information center. Click Application Server Toolkit > J2EE applications > Working with projects > Connector projects.
