Migrating Legacy Software Systems to CORBA based Distributed Environments through an Automatic Wrapper Generation Technique

摘要

One of the strategies for migrating legacy systems to distributed object-oriented environments is wrapping. Wrapping is a method of encapsulation that provides well-known interfaces for accessing legacy systems. The advantage of wrapping is that legacy systems become part of the new-generation of applications without discarding the value of the legacy applications. There, however, are many styles for interfacing with legacy systems. Application developers who want to migrate legacy systems to new environments and to use them have the burden of understanding and implementing various interfacing techniques. To solve this problem, we construct the extensible wrapping template classes for various interfacing styles and present an automatic wrapper generation method based on them.
