Provision of the calculation core of a private health insurance as a web service

The existing computer kernel implemented in C++ is called via a business logic written in Java. The business logic requires a great deal of input from the administrative staff. Due to its complexity, processing in business logic sometimes takes several seconds. Since this is not sufficient for a website for end customers, a web service is created that can quickly determine an approximate price with just a few entries. This web service runs on a JBoss application server. The inputs to the web service are delivered in a customer-specific XML exchange format, translated by the web service into the data format of the computing core and then called up by the computing core. This supplements standard values for data fields that are necessary for the calculation and performs the calculation. The result is then returned to the caller via the Web service. The implementation of the website for the end customers is not part of this project.
