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

The presentation layer is the outermost layer of an application that provides user 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),the design 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 required for the extraction of design-level information and further modernization. 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 Edition Platform. The proposed approach is evaluated on well-operative open-source Enterprise Applications. The validation results demonstrate the 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.

Making Java EE Cool Again: Building MongoDB-Based Web Services Using JPA and EJB

Despite its dominating role for developing large-scale enterprise applications, Java Enterprise Edition (EE) has always been seen critically by many developers, in particular from the web and open source communities. In recent years, the discussion about its decline and replacement e.g. by scripting languages such as Python or JavaScript has therefore gained momentum. On the other hand, Java EE has evolved towards being more flexible, lightweight and simpler to use and offers unique features still not available out-of-the-box on other platforms, such as support for distributed transactions. Therefore, in this paper an approach is presented, how a Java EE-based application supporting elderly people could be designed to make use of a modern NoSQL database (namely MongoDB), while preserving its unique features. The presented approach demonstrates not only the feasibility of such an architecture, but also supports the claim that Java EE still is a highly relevant and powerful platform for building modern applications.

Pengembangan Aplikasi E-Smes Berbasis Android dengan Waterfall Method Sebagai Solusi Pemasaran dan Pengelolaan Usaha UMKM

Cooperatives and MSMEs (Micro, Small, and Medium Enterprises) are some of the sectors that make a positive contribution to economic growth in Indonesia. The contribution obtained from the existence of MSMEs to GDP reaches 60% with the employment of 116.7 million people or 97.02% of the total workforce that is already working. Even though they have a big role, on the one hand, MSMEs have not been able to optimally manage their business, especially related to business management. The majority of MSME actors have not benefited from the use of digital technology because most MSME business actors have not fully understood the importance of using digital technology. The E-SMEs applications that will be developed for partners in this research are applications built using Java Enterprise Edition (JEE) technology. Java Enterprise Edition technology is a Java development for enterprise solutions, ranging from web-based applications using servlets and JSPs and android-based applications. The advantages of Java Enterprise Edition technology can create a reliable and portable application because Java can be implemented on various platforms and operating systems. In making this application using the Waterfall method which refers to the system development process model called the System Development Life Cycle (SDLC). This research method is a research and development method with the ADDIE approach. The developed e-SMEs application can later be used by Fiara Sulam to do online marketing and also digitally manage their finances.Keywords : E-SMEs MSMEs; Business Management

Използване на генератори на код при създаването на готови шаблони за разработка на приложения

Code generation is basically about writing programs that write programs. Given today’s complex code-intensive frameworks, such as Java 2 Enterprise Edition (J2EE), Microsoft’s. NET and Microsoft Foundation Classes (MFC), it is becoming increasingly important that we use our skills to create programs which aid us in developing our applications. Generally speaking, the more complex the framework is, the more appealing you will find a code generation solution. Many object-oriented programming (OOP) languages lack reusability and flexibility, and require a similar code to be written repeatedly. This paper reviews the code generators that are most useful for implementation in applications for automatic code generations, their pros and cons, where they are most widely used nowadays, as well as their versatility. In Visual Studio we use the term “scaffolding” when we want to generate identities automatically. When we start a new ASP.NET project, it genrates a template where we start from.

Software for automated reading of sunshine duration by Digital Image Processing

The present study aims to demonstrate the benefits and results obtained from software for filtering, processing and managing sunshine duration monitored by heliographs, in meteorological stations. The source code of the software was developed using the Java EE 7 (Java Enterprise Edition) programming language, based on internet applications. Information storage and management was performed by the MySQL 5.7 Database Management System (DBMS). Digital image processing techniques, incorporated in the software, allowed to count sunshine duration in an automated and standardized way, eliminating errors due to the complexity and subjectivity in the measurement observation, performed manually. Processing routines were implemented to apply filters in the spatial domain, enhancing digital images of sunshine data, to better identify parts of interest and ensure quality in the accounting process. For software validation, a set of September 2015 sunshine data, provided by the Lageado Meteorological Station of the School of Agricultural Sciences (UNESP) of Botucatu - SP, was used. In which, comparisons between readings performed by the computer program and readings performed manually showed MBE values of 0.130 hours (rMBE = 1.908%), RMSE of 0.259 hours (rRMSE = 3.791%) and R of 0.998. Indicating that the software can be used to read sunshine data, as it ensures automation, standardization and speed in the process.

User-Centric Cyber Disaster Recovery as a Service

In a world of interdependent economies and online transactions, a large volume of data hosted on the cyberspace a daily bases. Cyber threats and attacks are steadily increasing. Most time, these threats and attacks are targeted at service providers but service users are greatly affected by the attacks due to their vulnerability level. When disasters knockdown the infrastructures of a single service provider, it will have ripple effects on thousands of innocent service users. Therefore, service users need more than ever to prepare for major crises targeted at their service providers. To cope with this trends, every service user requires an independent business continuity plan (BCP) or disaster recovery plan (DRP) and data backup policy which falls within their cost constraints while achieving the target recovery requirements in terms of recovery time objective (RTO) and recovery point objective (RPO). The aim of this paper is to develop a model for a user-centric disaster recovery system to enable service users to independently develop their data backup policies that best suits their remote databases, and host same as a cloud service deployable on public cloud for users to subscribe to and be billed on pay-as-you-go billing model. The system developed is highly compatible with MYSQL, MSSQL and Oracle databases. A combination of Dynamic System Development Methodology (DSDM) and Object- Oriented Analysis and Design Methodology (OOADM) were used to design the system while Java Enterprise Edition (JEE) is used to develop the system. The encryption and compression mechanisms of the system were tested with various sizes of backup files ranging from 64 Kb to 20Mb and several performance metrics such as (1) Encryption time; (2) Compression size; (3) CPU clock cycles and battery power are compared and analysed with some well-known encryption and compression algorithms.

The Integrated Management of Information about the Geodetic Point Fields—A Case of the Czech Republic

The geodetic point fields play a crucial role in measuring a terrain, in surveying, and mapping applications. Due to the rapid development in the domain of information technologies, it makes sense to consider using the database and web technologies to manage and disseminate the available information about the geodetic point fields. The paper presents the creation of a spatial database which integrates the information about the various kinds of established geodetic point fields (horizontal, vertical and gravitational) with the aim of enabling their effective management. Furthermore, based on the integrated spatial database, the prototype of the new information system of geodetic point fields has been developed. The functionality of the prototype also considers the requirements coming from the international efforts, i.e., the Infrastructure for Spatial Information in Europe (INSPIRE) directive. The prototype, based on Java Enterprise Edition (EE) technology, implements the features reflecting the cyber-security issues and ensures the modularity and scalability of the system, which is important for further development of the system and dissemination and accessibility of the information about the geodetic point fields via modern web technologies.

A Software Development Methodology for Secure Web Application

In recent years, there has been a demand for Web applications with complex functions. In addition, most web applications efficiently manage data based on databases. While the key and critical dimension of developing these Web applications is analysis and design, most object-oriented analysis and design methods do not have a consistent view of the database. In addition, Java Enterprise Edition (EE) -based technologies are used in Web application implementations, but they do not provide any correlation with the database. On the other hand, as users' demands for security increase, security becomes more important. To this end, Java EE and database systems provide security solutions. However, it does not provide any correlation with object-oriented analysis and design methodology. As a result, it is difficult to develop secure web applications in a consistent way from analysis to implementation. In this paper, we propose a consistent software development methodology from analysis to implementation of secure web applications. The proposed software development methodology for web application development uses UMLsec, a security-emphasized modeling language, and object-relational (O-R) mapping for relational database design. It also uses Java servlets and SQL to implement analysis and design results based on role-based access control (RBAC). The software development methodology for the secure web application proposed in this paper has been applied to the development of the online banking system, from the design stage of the user's requirements analysis to the implementation of the web application.

Improving efficiency for ensuring data group anonymity by developing an information technology

Widespread introduction of methods that ensure anonymity of information about individual groups (teams) of respondents in the field of official statistics is restrained by the lack of relevant industrial information technologies and systems. A three-level client-server architecture of an information technology providing data group anonymity was provided in which clients, application servers and databases are united into a local network to enhance security of primary data. A conceptual data model covering all key components of group anonymity was described. Implementation of the technology based on the Java Enterprise Edition 8 platform, Oracle GlassFish Server application server, MySQL database server and SciLab engineering calculations system wase considered. The information technology enables provision of group anonymity of data in the event of a threat of its violation by analyzing data of an auxiliary microfile. The technology provides operations for constructing fuzzy group models using a genetic algorithm and modification of a microfile with the help of a mimetic algorithm which enables effective provision of anonymity by introducing minor insignificant distortions into data. Application of the technology was illustrated by solution of the task of providing anonymity of a military group based on real data of American Society Survey, 2013. It was shown that solving the problem by a team of five specialists has enabled at least two and a half times faster the process of preparation of a microfile than by the use of an existing technology

The Framework for Web-Based Automated Online Question Paper Generator through JEE

Examinations are an indispensable part of a student’s life. In the conventional mechanism, the question paper generation is time-consuming work for the faculty members of the educational institution. Every educational institute mandatorily expects exam setters to follow its own typesetting format. We have designed the automated question paper setting software to be user-friendly so that, paper setters can overcome from the typographic problem. Presently in most of the educational institutions question papers are set manually. It is time-consuming work and there may be chances of repetition of the same questions. So, in order to make the question paper generation more convenient to use, the web application is developed using Java Enterprise Edition (JEE) that can be accessed from LAN/Intranet.The application comes with the Admin Module and Teachers Module. The Admin grants access to the users by registering them. The faculty can access the system once they are registered. The faculty can enter questions in the database daily as per their free time. In this way, the question pool can be generated. The questions are approved by the chairperson and substandard questions are discarded. The question paper is then generated by selected course experts. The Fisher-Yates Shuffling algorithm used to choose questions randomly from the pool of questions from the database. Text Mining Algorithm aids in duplicity removal from the paper. The generated question paper will be in Word Format. In our application, we assure better security, removal of duplicity, cost-effectiveness, and human intervention avoidance. It can be used by small-scale and large-scale institutions.
