Technique for integrating NonStop CORBA program with legacy system
Yongyan Guo · Journal of Zhejiang University of Technology · 2004
To develop business-critical enterprise application based on NonStop CORBA technique, lots of existing non-CORBA-based client/server, i.e. legacy systems, should be integrated into the application, and wrapping technique should be used to avoid rewriting the codes of the legacy systems. Legacy wrapping technique that enables a CORBA-based program to interoperate with legacy system is introduced in detail. With the technique, legacy wrapper, which is a NonStop CORBA program that wraps around a legacy system so that the legacy system can be integrated with CORBA programs, is created. Taking C~\{++\} pathsend client wrapper as an example, steps for creating legacy client wrapper are presented and significant codes are given in detail. The technique has been used in several NonStop CORBA applications.
