In this article there are analyzing models of enterprise information portals and their creation properties, usage of components created by Java technologies and open source principle for projection and developing of enterprise intranet portal model, J2EE technologies usable in programmed realization of portals, and usage possibility of portlets.

Analysis of already created portals, which appeal to national research and development works presentation, are made. Lacks and advantages of existing portals are overlooked and considered for prototype development. National research and development portal functions are described and solution is presented. Product was built as a specific content management system (CMS). The range of CMS products offers more than 10 different functions, but not all of them are necessity. The most useful functions are chosen and produced for this product. The need of architecture sketch occurs, when creating CMS or running a CMS-like website. Separation from structure, contents and representation issue is described and solutions are provided.

Las capas de abstracción son componentes de software que permiten encapsular funcionalidades de un sistema permitiendo la reutilización de componentes a través de una interfaz de programación estandarizada. El objetivo del presente trabajo de título es desarrollar 2 capas de abstracción que permitan agilizar los tiempos de desarrollo de aplicaciones Web bajo la arquitectura J2EE. Estas capas están enfocadas al desarrollo de componentes EJB, y la otra para el desarrollo de capas de persistencia vía JDBC. El surgimiento de estas capas se plantea debido a los largos tiempos de desarrollo que se tienen al usar EJB y JDBC directo para desarrollar servicios y persistencia. Lo anterior se justi ca por varias razones, por ejemplo, en el caso de los servicios EJB existe una gran cantidad de archivos que se tienen que manipular para hacer un EJB, lo cual trae multiples con ictos en el sistema de control de versiones cuando trabajan varios desarrolladores simultáneamente en la capa de servicios, o bien la di cultad para tener traza de errores cuando se tienen problemas de con guración de estos archivos y otras clases de problemas referidos a la falta de automatización de ciertos procesos repetitivos de invocación de implementaciones nales y manejo de excepciones. En el caso de la persistencia, los problemas típicos que se plantean son las tareas repetitivas y conducentes a error, como por ejemplo, obtención y cierre de los recursos, consultas mal escritas, validaciones de largo, tipo y otras que no se efectúan antes de la ejecución de consultas, complejidad y código poco mantenible para hacer consultas con ltros dinámicos, la asociación de valores de los resultados de las consultas a objetos de negocios muchas veces se ve replicada, etc. Todo lo anterior induce la necesidad de crear una abstracción que permita hacer todas estas tareas de una manera lo más simple posible tratando de no perder algunas de las características que tienen estas tecnologías. El resultado nal corresponde a 2 capas de abstracción, la primera tiende a facilitar la creación de EJB, de manera de que el desarrollo de estos mismos involucre menos procesos de con guración y manejo de archivos, como a su vez tener cierto nivel de independencia de la tecnología EJB en términos de encapsularla al desarrollador. La segunda por su parte, permite encapsular las tareas de obtención de recursos y conectividad a nivel de aplicación contra la base de datos, en conjunto con la generación y ejecución de consultas SQL y la transformación de datos de objetos de negocios a datos del modelo relacional. Como resultado de este trabajo, a través del uso de métricas de comparación, se pueden notar las diferencias en tiempos de desarrollo, facilidad de mantención y complejidad entre una solución usando capas de abstracción versus una solución sin ellas. Cabe destacar que ambas capas de abstracción en de nitiva son capas generadoras de código, con la característica que el código generado se hace en tiempo de ejecución, lo cual tiene el bene cio que no es necesario tener código generado dentro del código de las aplicaciones que utilicen estas capas de abstracción.

Nowadays, with the rapid development of Information technology, workflow management technology has undoubtedly become the basic component of enterprise information system construction, the research and application level regarding workflow management technology directly determine the level of enterprise information system. By virtue of using workflow management system within enterprises, could advance the operating efficiency of business processes and enhance enterprise competition ability. This paper describes the origin and status of workflow management, analyses on the base of the workflow reference model of Workflow Management Coalition; discusses the overall requirements of workflow management system, especially for large-scale enterprises, which includes workflow engines, process design tools, administration and monitoring tools, and client tools thesis four essential components; as well as studies on the workflow modeling techniques and adopts the method based on UML activity diagram to achieve modeling. Along with proposes a design and realization method concerning how to construct a workflow management structure, which utilizes J2EE lightweight workflow engine to meet changeful business processes and diverse deployment environments.

The Swedish field of digital X-ray imaging has since several years relied heavily on distributed information systems and digital storage containers. To ensure accurate and safe radiological reporting, Swedish software-firm eCare AB delivers a system called Feedback—the first and only quality assurance IT support product of its kind. This thesis covers several aspects of the design and implementation of future versions of this software platform. The focus lies on distributed directory services and models for secure and robust data propagation in TCP/IP networks. For data propagation, a new application, InfoBroker, has been designed and implemented to facilitate integration between Feedback and other medical IT support systems. The directory services, introduced in this thesis as the Feedback Directory Services, have been designed on the architectural level. A combination of CORBA and Java Enterprise Edition is suggested as the implementation platform.

At the moment, two main web platforms have the monopoly of web service business; NET and J2EE have been competitors in this area for many years. Within last years, a technological advance has occurred with the appearance of Mono, an open source project that allows NET technologies to be taken into operating systems other than Microsoft Windows. This opens an information gap that needs to be solved with a new and actualised performance analysis. This thesis work identifies the performance characteristics of the web platforms on heterogeneous systems. The aim of this study is to investigate different performance characteristics of .NET and J2EE web services in heterogeneous systems. The student systems are Windows 7 and Ubuntu Linux. A set of web services is built following different service structures, which are then exposed to some quantitative and qualitative test following predefined criteria. The results demonstrate that both .NET and J2EE are suitable web platforms under different circumstances, based mostly on the communication protocol and operating system. This work identifies the best combination of web platform and operating system for each of the web service structures, which can vary for each company.

Für die Entwicklung komplexer Produkte werden eine Vielzahl unterschiedlicher IT-Systeme eingesetzt. Die softwaretechnische Verknüpfung dieser Systeme ermöglicht den automatisierten Datenaustausch und damit einen schnellen und reibungslosen Ablauf der Produktentwicklung. In dieser Arbeit wird eine komponentenbasierte und generische Verknüpfung von IT-Systemen auf Basis von Webservices und eines Enterprise Service Bus vorgestellt. Die Verknüpfung ist durch die Nutzung standardisierter Schnittstellen plattformunabhängig und erweiterbar. Zudem ermöglicht sie eine lose Kopplung der beteiligten IT-Systeme, wodurch ein Austausch bzw. eine Änderung der IT-Systeme vereinfacht wird. Als Referenzrealisierung wird die Verknüpfung der IT-Systeme Energy Navigator und Virtual Reality Control Platform vorgestellt, die im Rahmen des Projekts eniPROD (Energieeffiziente Produkt- und Prozessinnovationen in der Produktionstechnik, http://www.eniprod.de) insbesondere für die Entwicklung energieeffizienter Werkzeugmaschinen entwickelt wurden.
