They provide a common client interface to any set of resources - databases , external systems , and others 它們?yōu)樗械馁Y源集(數(shù)據(jù)庫、外部系統(tǒng),等等)提供了一組通用的接口。
For example , the jca common client interface defines the interface shown in listing 4 , which should be implemented by an mdb wishing to be driven asynchronously by a cci connector 例如, jca公共客戶端接口( cci )定義了清單4所示的接口,希望由cci連接器異步驅(qū)動(dòng)的mdb應(yīng)當(dāng)實(shí)現(xiàn)這些接口:
J2ee components running within the application server make calls to the resource adapter through the common client interface , and the resource adapter translates these calls into corresponding calls on the underlying information system using a native protocol J2ee組件應(yīng)用程序服務(wù)器中運(yùn)行,并通過通用客戶端接口( common client interface , cci )產(chǎn)生對資源適配器的調(diào)用,資源適配器使用固有的協(xié)議將這些調(diào)用解釋為相應(yīng)的對基礎(chǔ)信息系統(tǒng)的調(diào)用。
