Common Client Interface (CCI) for outbound communication

The CCI interfaces for outbound communication are contained in the packages javax.resource.cci and net.fsc.jca.communication.cci. For outbound communication, the CCI offers almost the same functionality as the BeanConnect-specific interfaces (with the exception of the additional functionality with UTM partners offered by the EISUpicConnection interface). You find information on the program framework using the CCI interface in Program framework for Common Client Interface (CCI).

Connection factory interfaces

In your EJB code, you use a connection factory to set up a connection. CCI provides the following connection factory interfaces:

• javax.resource.cci.ConnectionFactory

• net.fsc.jca.communication.cci.BCOltpConnectionFactory

• net.fsc.jca.communication.cci.BCUpicConnectionFactory (only if the EIS partner is an UTM application)

The BCOltpConnectionFactory interface and the BCUpicConnectionFactory interface extend the javax.resource.cci.ConnectionFactory interface without providing additional functionality.

Using the BCOltpConnectionFactory or BCUpicConnectionFactory interface makes sense if you want to verify that communication is processed via the OSI-TP or UPIC protocol respectively. Example 5 on Connection factory interfaces applies analogously. It is recommended that you use the interface javax.resource.cci.ConnectionFactory.

Connection interface

The CCI interface for the outbound communication is javax.resource.cci.Connection.
