Interface ConnectionFactoryAdapter

public interface ConnectionFactoryAdapter

The connection factory adapter is responsible for creating and closing connections for a specific resource (such as, JDBC or JCA). When a connection is created, the connection factory adapter uses the information in the connection retrieval info object to create a connection. For example, if the resource is JDBC, the connection retrieval info object contains a user and password that the connection factory adapter uses to ask the JDBC resource for a connection.
