Detection of J2EE Patterns based on Customizable Features

Abstract

Abstract-Design patterns support extraction of design information for better program understanding, reusability and reengineering. With the advent of contemporary applications, the extraction of design information has become quite complex and challenging. These applications are multilingual in nature i.e. their design information is spread across various language components that are interlinked with each other. At present, no approach is available that is capable to extract design information of multilingual applications by using design patterns. This paper lays foundation for the analysis of multilingual source code for the detection of J2EE Patterns.

Realization of Presentation layer information of Legacy Java Enterprise Applications Through Design Pattern’s Recovery

“…These features can be developed to increase the quality of the image and find other patterns. Previously, the catalog of feature types of the J2EE Design Pattern was presented [1,10]. However, only four patterns were realized to represent Presentation Tier Information including Front Controller, Intercepting Filter, and Composite View Patterns…”

“…To detect the complete catalog of J2EE Patterns for the Presentation Tier, the existing approach [1] needs enhancement as tool availability is deficient to observe all 9 J2EE Patterns about Presentation Tier. For this purpose, the Pattern Detection Engine (JPDE) was upgraded with the capability to notice patterns of the presentation tier.…”

“…During the development and maintenance of software applications, consistency of documentation with the design of an application is essential. Legacy software systems [1][2][3] are difficult to maintain and upgrade due to obsolete or missing design documentation. It is also observed that the available documentation does not match the original design due to changes and enhancements made over time.…”

“…This layer encapsulates graphical design and user interaction code. The recovery of presentation tier logic [1] with the help of different design patterns can help a great deal for understanding and redesigning the structure of an application.…”

“…However, complete detection of presentation tier J2EE Pattern has not been presented so far. The existing approach supports the only partial recovery of J2EE Patterns within the presentation tier [1]. Therefore, to be able to see the presentation tier logic implemented, all the design patterns present in a system must be detected and visualized.…”
