Java IAQ: Infrequently Answered Questions
The Java IAQ: Infrequently Answered Questions by Peter Norvig Q: What is an Infrequently Answered Question? A question is infrequently answered either because few people know the answer or because it is about an obscure, subtle point (but a point that may be crucial to you). I thought I had invented the term, but it also shows up at the very informative About.com Urban Legends site. There are lots

Pekka's Blog: Java Virtual Machine developer documentation
Saturday, January 9, 2010 Java Virtual Machine developer documentation So you want to be a Java virtual machine hacker but don't know where to start? One obvious starting point is to navigate your way through the large body of developer documentation. For a JVM developer, the most important document is the The Java Virtual Machine Specification and its companion document Clarifications and Amendme
Compiling to Java as a target language
In my advanced compilers class, we cover a range of intermediate and target languages. C is a popular target language for performance reasons, but Java has often-overlooked advantages. Some of Java's less-utilized features conspire to make it an easy target for high-level language constructs, e.g., lexically scoped closures become anonymous classes. It takes roughly a third to half the time (and c
Javaを紐解くための重点キーワード：JMS
■JMSとは？ JMSは通称「MOM」（メッセージ指向ミドルウェア）と呼ばれるエンタープライズメッセージングシステムにアクセスするための標準APIです。つまり、メッセージングシステムそのものの実装ではなく、MOMのサービスを利用するためのJavaベースの標準インターフェイスであるということです。JMSで定義されている仕様はベンダ・ニュートラルであり、どのMOMにアクセスする場合でも、一部の属性のみに個別の情報を定義するだけで、JMSアプリケーション自身は共通の手順と構成でシステム構築を進めることができます。 また、JMSを利用することで複数のアプリケーションがメッセージの交換を通じて通信することができるようになります。そのメッセージング形態はピア・ツー・ピア型であり、JMSアプリケーションは通常「クライアント」に位置付けられます。JMSはJ2EEのほかのサービス（JTA/JTS、JNDI、
Object Computing, Inc. - Java News Brief - March 2009
Introduction The goal of this article is to provide a fairly comprehensive introduction to the Clojure programming language. A large number of features are covered, each in a fairly brief manner. Feel free to skip around to the sections of most interest. Please send feedback on errors and ways to improve explanations to mark@objectcomputing.com, or fork the repository and send a pull-request.

Clojure
Clojure is a robust, practical, and fast programming language with a set of useful features that together form a simple, coherent, and powerful tool. The Clojure Programming Language Clojure is a dynamic, general-purpose programming language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming.
スレッド毎にClassLoaderを用意してクラスパスを割り当てる - ihirokyの日記
ThreadにはsetContextClassLoader()というメソッドがあって、スレッド毎にクラスローダを割り当てることができる。要するにスレッドを作るときにそのスレッド専用のjarファイルなりクラスパスを割り当てることができる。 これを確かめるためにクラスパスを引数に受け取り新しく起動するスレッドにそのクラスパスを割り当てるプログラムを書いた。 クラスパスを割り当ててスレッドを起動するクラス URLClassLoaderを作ってクラスパスを追加する。作ったURLClassLoaderを起動するスレッドに設定する。 package ihiroky.context.sample; import java.io.File; import java.net.URL; import java.net.URLClassLoader; import java.util.LinkedList; i
