Creating and Using Platform-Independent Connectors 
The connector framework provides the infrastructure to create platform independent connectors that enable access to Web applications, either the back-end applications of your organization or applications available through external Web services. The connectors comply with the Java 2 Platform Enterprise Edition (J2EE) standard which includes the J2EE Connector Architecture (JCA) specifications.
Note
The JCA refers to data sources such as Enterprise Information Systems (EIS) and resource adapters as an alternative term for connectors.
The connector framework resides on the WebAS Java stack, the J2EE engine. The connectors can be used and implemented in a managed environment, which offers advantages, such as JNDI lookup, connection pooling, and user management. Working in non-managed mode is also possible, but the implementation and deployment of a connector is affected accordingly. For more information, see Non-Managed Mode and Connector Deployment.
Integration
The connector framework consists of the connector framework API and the connector wizard for convenient development of a new connector project in NetWeaver Development Studio.
The connector framework extends the JCA 1.0 standard, to meet the requirements of SAP NetWeaver Portal users.
Note
The connector framework supports JCA 1.5, although it does not implement it. You can download the latest version of the JCA standard at java.sun.com.
This guide describes the concepts of the connector framework structure, management, and functionality, as well as installation information, development environment prerequisites, and information about the deployment of connectors created with the generic API.
