ABSTRACT:
Disclosed is a system and method for generating EJB components by extracting reusable business logic from servlet programs that is one of web program languages used in web-based applications. The system a servlet code analyzer that is a reverse engineering module for analyzing the existing servlet program source, a visualizer for visualizing the analyzed information, a business logic extractor for extracting a reusable business logic, and an EJB component generator for generating the EJB components using the extracted information. The servlet code analyzer considers the flexibility of coding permitted by the servlet program and the use of a multi-language, and the visualizer helps the understanding of the existing legacy program. The business logic extractor extracts the reusable module by extracting the business logic within many user interface related codes, and thus enable the reuse of software. The EJB component generator generates java codes in a jar file that can be deployed.
