1.1.1.3 HTTP Servlet Based Synchronous Deployment Pattern
The HTTP servlet deployment pattern will be used in integration scenarios where the external system connecting to Oracle Banking Treasury Management wants to connect to Oracle Banking Treasury Management using simple HTTP messages.
This is especially applicable to systems such as the following:
- Systems that are not ‘EJB literate’, i.e., are not capable establishing a connections with Oracle Banking Treasury Management based upon the EJB interface; and/or
- Systems that prefer to use a simple http message based approach without wanting to use SOAP as the standard.
In this deployment pattern, the external system will make an HTTP request to the Oracle Banking Treasury Management servlet.
For this deployment pattern, Oracle Banking Treasury Management will display a single servlet. The actual request will be in the form of an XML message. This XML message is embedded into the body of the HTTP request sent to the Oracle Banking Treasury Management servlet.
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 once again embedded within the body of the response HTTP message. The transaction control for the processing will stay with the Oracle Banking Treasury Management.
