" Given that web service invocations are always remote across the internet, developing rigorous and responsive web service client applications has always been a challenge for architects and developers working with SOA. JAX-WS 2.0 comes with one effective solution to this problem: asynchronous web service invocation, with which a web service client may interact with a web service in a non-blocking, asynchronous approach. In this article, we will provide an exposition of this technology with examples built upon the reference implementation. Our examples utilize JDK 5.0, JAX-WS 2.0 reference implementation (RI), and Tomcat 5.5. JAX-WS 2.0 requires JAXP 1.3. To replace the JAXP 1.2 released with JDK 5.0 with this newer version, one approach is to download the JAXP 1.3 RI, and copy the endorsed directory under /lib of its installation home to %JAVA_HOME%/jre/lib. We need to copy the jaxp-api.jar of JAXP 1.3 RI to %JAVA_HOME%/jre/lib/endorsed as well. To make Tomcat 5.5 work with JAX-WS 2.0, readers need to copy all the .jar files under the /lib directory of the JAX-WS 2.0 RI installation to the %CATALINA_HOME%/shared/lib directory. As of this writing (in addition to Tomcat 5.5), Sun Java System Application Server 9.0, GlassFish, and Celtix also support JAX-WS 2.0. xFire is in the process of completing its implementation of this specification. Since asynchronous web service invocation in JAX-WS 2.0 is built upon the concurrent programming support in JDK 5.0 introduced with the java.util.concurrent package, we will start from there."

Java Topic / Java tutorial Encapsulation is the mechanism that binds together code and the data it manipulates and keeps both safe from outside interference and misuse. Encapsulation is one of the three object oriented concepts.

Scala is a general purpose programming language designed to express common programming patterns in a concise, elegant, and type-safe way. It smoothly integrates features of object-oriented and functional languages. It is also fully interoperable with Java

"Clojure is a dynamic programming language that targets the Java Virtual Machine (and the CLR ). It is designed to be a general-purpose language, combining the approachability and interactive development of a scripting language with an efficient and robust infrastructure for multithreaded programming. Clojure is a compiled language - it compiles directly to JVM bytecode, yet remains completely dynamic. Every feature supported by Clojure is supported at runtime. Clojure provides easy access to the Java frameworks, with optional type hints and type inference, to ensure that calls to Java can avoid reflection. Clojure is a dialect of Lisp, and shares with Lisp the code-as-data philosophy and a powerful macro system. Clojure is predominantly a functional programming language, and features a rich set of immutable, persistent data structures. When mutable state is needed, Clojure offers a software transactional memory system and reactive Agent system that ensure clean, correct, multithreaded designs. I hope you find Clojure's combination of facilities elegant, powerful, practical and fun to use."
