3.2.4 Web Services Based Synchronous Deployment Pattern

This topic provides information on web services based synchronous deployment pattern of securing the gateway services.

The web services deployment pattern will be used in integration scenarios where the external system connecting to Oracle FLEXCUBE wants to connect using standards-based, inter-operable web services.

This deployment pattern is especially applicable to systems which meet the following broad guidelines:

• Systems that are not EJB literate, it means such systems are not capable of establishing connections with Oracle FLEXCUBE based upon the EJB interface; and/or
• Systems that prefer to use a standards-based approach

In this deployment pattern, the external system will use the SOAP (Simple Object Access Protocol) messages to communicate to the Oracle FLEXCUBE web services.

The services displayed by Oracle FLEXCUBE are of a message based style, that is the actual request will be in the form of an XML message, but the request will be a payload within the SOAP message. After the necessary processing is done in Oracle FLEXCUBE based on the request, the response is returned to the external system as an XML message which will be a payload within the response SOAP message. The transaction control for the processing will stay with the Oracle FLEXCUBE.
