The following scenario is about connecting
clients to applications that participate in transactions.
The Java EE Connector Architecture (JCA) provides support for clients that are using Java Transaction API (JTA). Through JTA, client management is simplified and accomplished using Java Platform, Enterprise Edition (Java EE). The JCA specification also supports resource adapters that you can use to connect applications to eXtreme Scale clients. A resource adapter is a system-level software driver that a Java application uses to connect to an enterprise information system (EIS). A resource adapter plugs into an application server and provides connectivity between the EIS, the application server, and the enterprise application. WebSphere eXtreme Scale provides it own resource adapter, which you can install without any required configuration.
