The State of the Feather
The State of the Feather An Overview and Year In Review of The Apache Software Foundation The Overview • Not a replacement for “Behind the Scenes...” • To appreciate where we are - • Need to understand how we got here 2 In the beginning... • There was The Apache Group • But we needed a more formal and legal entity • Thus was born: The Apache Software Foundation (April/June 1999) • A non-profit, 501(c)3 Corporation • Governed by members - member based entity 3 “Hierarchies” Development Administrative PMC Members Committers Board Contributors Officers Patchers/Buggers Members Users 4 At the start • There were only 21 members • And 2 “projects”: httpd and Concom • All servers and services were donated 5 Today... • We have 227 members... • ~54 TLPs • ~25 Incubator podlings • Tons of committers (literally) 6 The only constant... • Has been Change (and Growth!) • Over the years, the ASF has adjusted to handle the increasing “administrative” aspects of the foundation • While remaining true to our goals and our beginnings 7 Handling growth • ASF dedicated to providing the infrastructure resources needed • Volunteers supplemented by contracted out SysAdmin • Paperwork handling supplemented by contracted out SecAssist • Accounting services as needed • Using pro-bono legal services 8 Staying true • Policy still firmly in the hands of the ASF • Use outsourced help where needed – Help volunteers, not replace them – Only for administrative efforts • Infrastructure itself is a service provided by the ASF • Board/Infra/etc exists so projects and people -
Hibernate ORM Query Simplication Using Hibernate
2016 3rd National Foundation for Science and Technology Development Conference on Information and Computer Science Hibernate ORM Query Simplication Using Hibernate Criteria Extension (HCE) Kisman Sani M. Isa Master of Information Technology Master in Computer Science Bina Nusantara University Bina Nusantara University Jl. Kebon Jeruk Raya No. 27, Jakarta Barat, DKI Jl. Kebon Jeruk Raya No. 27, Jakarta Barat, DKI Jakarta, Indonesia 11530 Jakarta, Indonesia 11530 [email protected] [email protected] Abstract— Software development time is a critical issue interfaced by a query. The software engineer will make in software development process, hibernate has been the query specified to database used. Each database widely used to increase development speed. It is used in vendor has their Structured Query Language (SQL). As database manipulation layer. This research develops a the development of software technology and most of library to simplify hibernate criteria. The library that is programming languages are object oriented, some called as Hibernate Criteria Extension (HCE) provides API functions to simplify code and easily to be used. Query engineer or software institutions try to simplify the associations can be defined by using dot. The library will query process. They try to bind object in application to automatically detect the join association(s) based on database. This approach is called as Object Relational mapping in entity class. It can also be used in restriction Mapping (ORM). ORM is a translation mechanism from and order. HCE is a hibernate wrapper library. The object to relational data, vice versa. ORM has “dialect” configuration is based on hibernate configuration. -
Objektově Orientovaný Přístup K Perzistentní Vrstvě V Prostředí Java Object Oriented Database Access in Java
Objektově orientovaný přístup k perzistentní vrstvě v prostředí Java Object Oriented Database Access in Java Roman Janás Bakalářská práce 2014 *** nascannované zadání str. 1 *** *** nascannované zadání str. 2 *** UTB ve Zlíně, Fakulta aplikované informatiky, 2014 4 ABSTRAKT Předmětem bakalářské práce „Objektově orientovaný přístup k perzistentní vrstvě v prostředí Java“ je analýza dostupných ORM aplikačních rámců pro programovací jazyk Java. Cílem je zjistit, který aplikační rámec je v současnosti nejlépe použitelný. Obsahem práce je také srovnání s technologií JDBC - porovnání výkonnosti jednotlivých řešení a popis používaných návrhových vzorů. Praktická část názorně ukazuje práci se zvolenými aplikačními rámci a výsledky výkonnostních testů. Klíčová slova: ORM, Java, návrhové vzory, JDBC, Hibernate, Cayenne ABSTRACT The subject of the submitted thesis “Object Oriented Database Access in Java” is analysis of available ORM frameworks for programming language Java. The goal is to determine which framework is the most applicable. The content is also comparison with JDBC technology – comparison of efficiency of each solutions and description of used design patterns. The practical part clearly shows work with chosen frameworks and results of efficiency tests.

Develop a Simple Web Application with Apache Wicket and Apache
Develop a simple Web application with Apache Wicket and Apache Geronimo Combine Wicket, Geronimo, and Apache Derby to form an open source Java Web development platform Skill Level: Intermediate Robi Sen ([email protected]) Vice President Department 13 LLC 10 Jul 2007 Apache Wicket is an innovative Java™ Web application framework that was introduced a couple of years ago. It helps simplify Web application development by clearly separating the roles of developers and designers. It lets you remove logical code from the view layer, eliminating the need for JavaServer Pages (JSP), providing a simple plain old Java object (POJO)-centric mode of development, and removing much of the need for XML and other configuration file formats. In this tutorial, learn how to set up your system to develop a simple Web application with Wicket, using Apache Geronimo as your application server and Apache Derby as the embedded database. Section 1. Before you start This tutorial is designed for developers who have found Java frameworks, such as Struts, lacking in needed functionality. If you're interested in developing Web applications in a more object-oriented manner, where the view is clearly separated from logic and there's minimal configuration and mapping, then Wicket is for you! This tutorial walks you through the basics of how Wicket works, while using Apache Geronimo to set up a Java Platform, Enterprise Edition (Java EE) server, Web server, and embedded database in just minutes. Combining Wicket with Geronimo lets you develop data-driven, scalable Web applications using software that's all open source.

In this paper, we will discuss ten programming languages: C++, C#, Java, Groovy, JavaScript, PHP, Schalar, Scheme, Haskell and AspectJ. We summarize and compare these ten languages on ten different criterion. For example, Default more secure programming practices, Web applications development, OO-based abstraction and etc. At the end, we will give our conclusion that which languages are suitable and which are not for using in some cases. We will also provide evidence and our analysis on why some language are better than other or have advantages over the other on some criterion. 1 Introduction Since there are hundreds of programming languages existing nowadays, it is impossible and inefficient -

Ebean Java Persistence (Dominik Dorn)
Meeting #44 EBean Java Persistence (Dominik Dorn) CoffeeScript & SASS (Clemens Helm) Brunch (w/ backbone.js) (Nik Graf – lightning talk) 2011-12-05 Dominik Dorn EBean Java Persistence just simple & powerful 2011-12-05 Dominik Dorn Overview ● What is EBean / Java Persistence + JPA? ● Architecture – where does it fit? ● Partial Objects + Fetch Graphs ● EBean Features ● Code... (maybe :) ) 2011-12-05 Dominik Dorn What is Ebean? ● open source Object Relational Mapping tool ● simple alternative to JPA (not like hibernate, eclipselink, etc.) ● “sessionless” API and simple query language (explained later) ● Fetch graphs + Partial Objects ● Lazy loading that just works. 2011-12-05 Dominik Dorn Architecture – Where does it fit? 2011-12-05 Dominik Dorn Differences to Hibernate/JPA ● Sessionless ● No EntityManager / Session / UnitOfWork – No merge(), persist(), attach() or detach() – Only save() and delete() ● Query Language ● Slightly different ● Optimized for fetch graphs and partial objects ● No hacks ● For wide tables / blobs & clobs etc. 2011-12-05 Dominik Dorn Partial Objects & Fetch Graphs ● TASK: Print an Invoice → get Order(date, items, total) + customer (name, email) + items ( name, price ) 2011-12-05 Dominik Dorn Partial Objects & Fetch Graphs ● Hibernate createQuery(“SELECT o FROM Order o WHERE o.id = ?”) → Lazy/eager loading Customer + Items → “Huge” traffic and memory requirements (blobs etc.) 2011-12-05 Dominik Dorn Partial Objects & Fetch Graphs ● EBean Order o = Ebean.find(Order.class) .select("date, total") .fetch("customer", "name,
