The demo viewer app (click for bigger image) Experimental Project Wonderland support (click for bigger image) What is it? The PDF Renderer is just what the name implies: an open source, all Java library which renders PDF documents to the screen using Java2D. Typically this means drawing into a Swing panel, but it could also draw to other Graphics2D implementations. We hope you will come up with co
type erasure is not evil
Sun has been taking a lot of flak for implementing Java’s generics with “type erasure”. They deserve it, of course, but the concept of type erasure has taken an beating as well and I don’t think it deserved to. Java has two compilation steps. In the first step, the Java compiler turns Java source code into JVM bytecode. During this phase, information about type parameters is available to the compi
OpenJDK: Project Lambda
This feature was delivered into JDK 8 which was released March 2014. The Project was dissolved by virtue of losing its sponsoring Group. Discussion about lambda expressions may be found on compiler-dev and core-libs-dev for compiler and libraries issues respectively. JSR 335 (Lambda Expressions for the Java Programming Language) supports programming in a multicore environment by adding closures an

Reading and writing bytecode Javassist is a class library for dealing with Java bytecode. Java bytecode is stored in a binary file called a class file. Each class file contains one Java class or interface. The class Javassist.CtClass is an absatract representation of
java.util.ServiceLoaderを使う。 - 設計と実装の狭間で。
DIコンテナやらOSGiやら使う程でもないけど、最低限の拡張性はとりあえず担保しておきたいので使う感じなのだけど、コアAPIに含まれているjava.util.ServiceLoaderは本当に使い辛い。 というか、そのままでは使えないのでユーティリティ的でいつも似てるけどちょっと違うコードをそこら中に書き散らす訳で。 まずは、javadocをちゃんと読んでクダサシ。 java.util.ServiceLoader<S> 作成するリソースは、最低４つ。ファイルの配置はこんな感じ。 実装を切り替える為のインターフェース package conf; /** * @author taichi */ public interface Service { String getName(); void execute(String parameter); } 定義したインターフェースのデフォルト実装 p
Apache Commons JCI - Apache Commons JCI - About
JCI is a java compiler interface. It can be used to either compile java (or any other language that can be compiled to java classes like e.g. groovy or javascript) to java. It is well integrated with a filesystem alteration monitor that can be used with the JCI compiling/reloading classloader. All the currently supported compilers feature in-memory compilation. The current implementation supports

What is Janino? Janino is a super-small, super-fast Java™ compiler. Not only can it compile a set of source files to a set of class files like the JAVAC tool, but also can it compile a Java™ expression, block, class body or source file in memory, load the bytecode and execute it directly in the same JVM. Janino is not intended to be a development tool, but an embedded compiler for run-time compila
google-guice - Google Code
Put simply, Guice alleviates the need for factories and the use of new in your Java code. Think of Guice's @Inject as the new new. You will still need to write factories in some cases, but your code will not depend directly on them. Your code will be easier to change, unit test and reuse in other contexts. Guice embraces Java's type safe nature. You might think of Guice as filling in missing featu
Apache Cassandra | Apache Cassandra Documentation
What is Apache Cassandra? Apache Cassandra is an open source NoSQL distributed database trusted by thousands of companies for scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.
