Adapter<br />

Stored in a Resource Adapter Archive (RAR) file, a resource adapter can be deployed on any<br />

<strong>Java</strong> <strong>EE</strong> server, much like the EAR file of a <strong>Java</strong> <strong>EE</strong> application. An RAR file may be contained in<br />

an EAR file, or it may exist as a separate file. See Figure 35–2 for the structure of a resource<br />

adapter module.<br />
