Realization of Presentation layer information of Legacy Java Enterprise Applications Through Design Pattern’s Recovery
Keywords:Java Enterprise Edition, Design Patterns, Extraction, Visualization, Design Recovery
The presentation layer is the outermost layer of an application that providesuser interface and communication services. This layer is responsible for session management, controlling client access, and validations within data from the client.In legacy enterprise applications like Java Enterprise Edition Platform (Java EE),thedesign considerations of the presentation layer are spread over different design patterns and cross-language constructs. Resultantly, the analysis of such applications becomes quite challenging due to their heterogeneity, essentially requiredforthe extraction of design-level information and furthermodernization. In this research,a flexible technique is presented to extract presentation tier information based on customizable feature types by recovering instances of presentation tier patterns of the Java Enterprise EditionPlatform.The proposed approach is evaluated on well-operative open-source Enterprise Applications. The validation resultsdemonstratethe extraction of presentation tier information through Design Pattern’s recovery.This prototype is validated on the repository of source code of Java applications as well on open source java applications.
