Back Cover

Java Connector Architecture (JCA) presents the JCA and identifies the scope in which a JCA-based adapter operates. The book quickly moves to the design methodologies employed in adapter using the JCA. The book then progresses to information about testing and deploying adapters in a production environment. Java Connector Architecture defines a development methodology and suggests analysis and design patterns, which are useful both for building connectors to legacy applications and for designing adapters for new applications.
