2.3 Web Services Based Synchronous Deployment Pattern

The web services deployment pattern is used in integration scenarios where the external system connecting to Oracle Banking Treasury Managment 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, that is, such systems are not capable of establishing connections with Oracle Banking Treasury Management based upon the EJB interface; and/or
• Systems that prefer to use a standards-based approach

In this deployment pattern, the external system uses the SOAP (Simple Object Access Protocol) messages to communicate to the Oracle Banking Treasury Management web services.

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