These topics provide information about accessing data resources.
The connection between an enterprise application and an enterprise information system (EIS) is accomplished through the use of EIS-provided resource adapters, which are plugged into the application server. The resource adapter plays a central role in the integration and connectivity between an EIS and an application server. It serves as the point of contact between application components, application servers, and enterprise information systems. A resource adapter must communicate with other components based on well-defined contracts that are specified by the Java Platform, Enterprise Edition (Java EE) Connector Architecture (JCA).
WebSphere® Application Server supports work context types that implement the new standardized SecurityContext, TransactionContext and HintsContext interfaces. The generic inflow context mechanism accepts implementations of the HintsContext interface, but the application server does not act upon these implementations of the HintsContext interface. The security inflow context mechanism does not map user identities from the EIS domain to identities in an application server domain. Identities provided by implementations of SecurityContext must be in a security domain of application server.
