Šiame darbe mes įvardinome J2EE projekto kūrimo problematiką. Ištyrėme įrankį Appfuse, kuris yra skirtas programuotojo darbui palengvinti. Appfuse atlieka J2EE internetinio projekto infrastruktūros generavimą, kompiliavimą, veiksmų automatizavimą ir kitas naudingas užduotis. Šį įrankį panaudojome Bendrabučių informacinei sistemai sukurti ir taip įsitikinti Appfuse nauda. Projektas buvo pradėtas greitai ir kodo rėmai leido programuoti šiuolaikiškai pagal trijų lygių architektūros schemą. Nereikėjo gilintis į sudėtingų technologijų, tokių kaip Spring ir Hibernate integravimą. Dokumente aprašėme naudojamos priemonės suteikiamus privalumus ir panaudojimą tyrimą. / In this paper we tried to look into J2EE project start and development problem. There are so many development tools to be used in project that causes the complexity. The used tools must be configured to communicate with each other and has different style of configuration. Build, testing, deployment tools must be implemented and m1anaged for every J2EE project. We analyze the solution Appfuse, which eliminates the problems mentioned above. Appfuse is open source project and program, which help fast and efficient software development. The proofs of concepts were illustrated by creating the Information System for Dormitories.

對於現代企業來說，應用系統與流程的整合並非新的需求，然而整合的複雜度與困難度卻隨著整體商業經營環境的善變日益加深，舊有的點對點應用程式整合架構已無法滿足這樣的一個環境，因此，市場上便出現了整合中介軟體(Middleware)這一類的產品來簡化複雜的傳統點對點整合架構。然而，這樣的一個做法仍然有標準以及架構不夠開放導致投資風險過高的缺點！ 相對於專屬系統，以J2EE平台為基礎的開放式架構於焉出現。他們遵循J2EE平台規格提供整合方案，以Application Server為中心，配合JCA、JMS及XML新標準，可整合新舊式系統，延展性高。而另外Web Services 是近兩年來的當紅炸子雞，為一種元件網路化的技術，透過Internet開放的標準(如Http、XML)公開讓人使用，其被視為是整合的明日之星！ J2EE架構運用在應用程式整合上是新一代的趨勢，遵循JMS以及JCA架構可讓各種不同的應用程式直接與J2EE應用程式做溝通，加上J2EE平台有著其他諸如延展性強、安全性高以及支援者眾多等優點，更使得這樣的一個整合解決方案更增無限魅力！但其也有著呼叫程式被特定協定或程式模式(如JMS、JCA)綁住而造成開發成本提高以及難度的增加等缺點。本研究擬運用Web Services之相關技術於現有之J2EE整合架構，並以一線上投保系統之內部企業應用程式整合作為範例以說明此架構之應用方式。 關鍵字：中介軟體(Middleware)、企業應用程式整合(EAI)、J2EE整合、JMS、JCA、Web Services。

The development process for creating J2EE web applications is complex and tedious, and is thus error prone. The quality of a J2EE web application depends on correctness of code as well as the efficiency and flexibility of its architecture. Although the J2EE specification has promised to hide the distributed nature of the application, application developers still have to be aware of this fact in both the design (architecture) and implementation (code) perspectives. In this thesis, we present the detailed design of our pattern-based J2EE development tool, RoadMapAssembler (RMA). RMA demonstrates how patterns can be used to generate efficient architectural code while also hiding the deployment logic and distributed nature of J2EE applications in the implementation perspective. Furthermore, it shows the generation of a J2EE framework as a process of assembling patterns in an incremental fashion using known inter-pattern relationships.

Since the search engine was first released in 1993, the development has never been slow down and various search engines emerged to vied for popularity. However, current traditional search engines like Google and Yahoo! are based on key words which lead to results impreciseness and information redundancy. A new search engine with semantic analysis can be the alternate solution in the future. It is more intelligent and informative, and provides better interaction with users.        This thesis discusses the detail on semantic search, explains advantages of semantic search over other key-word-based search and introduces how to integrate semantic analysis with common search engines. At the end of this thesis, there is an example of implementation of a simple semantic search engine.

El objetivo general de este trabajo de título es el de implantar inicialmente el uso de una nueva plataforma de desarrollo de aplicaciones Web realizada en JavaEE, al interior de la Subdirección de Informática en el Servicio de Impuestos Internos. Lo anterior mediante la construcción de una aplicación piloto que reúna las condiciones como prototipo para los posteriores desarrollos, administrando el cambio cultural que presenta este desafío. El Servicio de Impuestos Internos realiza diversos desarrollos de aplicaciones web, con el objetivo de apoyar a las áreas de negocio. Con el tiempo la construcción de estas aplicaciones se ha tornado cada vez más compleja debido a la falta e inexistencia de una plataforma tecnológica que permita potenciar el trabajo en equipo y la reutilización de soluciones y procesos. Se adquirieron las herramientas necesarias para la implantación de una nueva arquitectura de trabajo y se comenzó a desarrollar una aplicación que requería integración con la mayoría de los componentes informáticos utilizados en el Servicio. Finalmente se logró terminar la construcción del prototipo, resolviendo todas las complejidades presentadas debido a su interacción con el resto de los componentes y herramientas utilizadas. Esto permitirá facilitar los siguientes desarrollos pues muchas de las complejidades comunes en la construcción de aplicaciones web fueron resueltas para esta plataforma. Si bien el desarrollo de este piloto permitió resolver las complejidades técnicas con las que se verán enfrentadas otras aplicaciones, aun falta mucho por hacer, sobre todo en el ámbito de la gestión de calidad y la creación de documentación como proceso útil dentro de las etapas del desarrollo.

Diversos fornecedores oferecem implementações desta especificação, as quais são referenciadas como servidores de aplicação J2EE. Este mercado concorrido gera um novo desafio para departamentos de TI que compreende a avaliação e seleção de um produto J2EE adequado. A escolha de uma implementação é uma tarefa árdua uma vez que envolve uma avaliação conjunta de muitas características, tais como custo, desempenho, escalabilidade, flexibilidade e adaptabilidade, facilidades de uso e de gerenciamento, e conformidade com os padrões. Contudo, essa escolha é usualmente centrada em desempenho, uma vez que avaliar servidores de aplicação com base em todas as suas características é difícil. As abordagens atuais para avaliação de desempenho de servidores de aplicação têm se concentrado principalmente no uso da técnica de medição. Este trabalho, por sua vez, propõe a utilização de modelagem analítica e simulação, introduzindo uma abordagem para a avaliação de desempenho baseada em redes de Petri estocásticas. Para ilustrar a proposta, modelos para o servidor de aplicação JBoss são projetados e utilizados na derivação de métricas de desempenho. Os resultados obtidos são validados através da realização de medições em ambientes controlados

The goal of this work is to allow JBoss ESB to communicate with remote applications using REST. JBoss ESB is a platform that separates application logic from the process functions and enables communication between applications with different interfaces by sending messages. REST is an architecture that provides universal interface for communication between computer systems in the network. This work describes integration of REST communication architecture with JBoss ESB platform. The integration is divided into two parts. The input part accepts REST requests, propagates their content to the JBoss ESB and generates a response. The output part waits for the messages from JBoss ESB from which it creates the REST requests, sends them to the recipients and receives responses. The implementation puts emphasis on integration with the RESTEasy project. RESTEasy provides a framework that facilitates development of applications that support REST communication.

Viena iš technologinių sričių, kur galima pritaikyti modeliavimu grindžiamą architektūrą (MGA) yra Java Enterprise Edition (J2EE) informacinių sistemų kūrimas. Nors generuoti pilną programinį kodą taikant MGA metodus nėra įprasta, tačiau egzistuoja abstraktūs metodai, bei daliniai sprendimai leidžiantys daryti prielaidą, kad tai yra įmanoma. Remiantis egzistuojančiais abstrakčiais metodais ir daliniais sprendimais buvo sukurtas MGA metodas ir kodo generatorius, leidžiantis sugeneruoti visą programinį kodą pagal modelio duomenis. Sukurtas metodas buvo išbandytas su realia informacine MagicTest žinių testavimo sistema. Bandymas su realia sistema parodė, kad pasiūlytas MGA metodas gali būti sėkmingai taikomas JEE platformos informacinių sistemų kūrimui. / One of the technological areas where can be used model driven architecture (MDA) is Java Enterprise Edition (J2EE) development of information systems. Although to generate a complete program using MDA is not common, but there are some abstract methods, and partial solutions suggesting that this is possible. Based on existing methods of abstract and partial solutions new MDA method and code generator was created. Generator allows to generate software code based on the model data. The method and generator was tested with the real information MagicTest knowledge testing system. The test of the real system showed that the proposed MDA method can be successfully applied to J2EE platform for developing information systems.
