Integration in a distributed information system for a multinational company

The reinsurance group of the company has several subsidiaries worldwide, including Europe, Asia and U.S. linked together in a VPN. Our mission was to integrate the already existing, standalone, desktop win32 platform applications running at subsidiaries into the distributed J2EE-based information system of the headquarters.

The solution adopted rely on the commonly used HTTP 1.1 protocol, which is available on all used platforms. Each desktop win32 application loads our client dll, upload data via HTTP using this dll to the headquarters’ Sun Java System Application Server, here the data package is received by a Java Servlet and passed by JMS to a message driven bean which performs the Business Logic operations and store the results into an Oracle Enterprise DB Server.

This way the company obtained a distributed application capable of to input, process and store data from the subsidiaries, integrating them into the information system of the headquarters.
