" I am Johan den Haan, working for Mendix as CTO. This blog is personal, all opinions are mine and should be taken with a pinch of salt. I write about topics in the field of enterprise architecture and software engineering, like SOA, SOBA, MDE, MDA, MDD, DSL, etc. Johan den Haan on Twitter "
"Business Process Management functionality has been added to SwitchYard via the BPM Component work done in SWITCHYARD-174. The BPM Component leverages jBPM 5 (currently version 5.1.0.Final) under the hood to accomplish this.
To illustrate this new functionality, a new Quickstart Demo has been created. The business process is a "Help Desk" workflow, and is available in the quickstarts git repository under demos/helpdesk/. Let's start by looking at a graphical representation of the process:"
"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. In this article, we will provide an exposition of this technology with examples built upon the reference implementation.
The JAX-WS programming model offers two models for invoking operations asynchronously - polling and callback. Both methods allow the client to continue processing while waiting for a response."
" 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."
Merit campus provides the best online java training. Learn Java programming if you are a beginner, Intermediate or an expert. Practice tests on creation of java, servlets, JDK, JRE, JVM, JIT, Java Compiler and Evolution of Java etc.
Java Topic / Java tutorial There are few other features of Java apart from Applets, Security, Portability and Servlets which are also important. These are also called as Java Buzzwords. Which are Simple, Object Oriented, Robust, Multi Threading, Architecture Neutral, Interpreted and High Performance, Distributed and Dynamic
We are group of passionate programmers, who would like to help the interested students learn the art of programming. At Merit Campus, we are trying to bring all the programing related information into one place. Here you can read the topics, watch videos, answer questions, write programs, track your progress, compare with other students and finally publish your skills or include it in your resume
This video explains about who has created java, when was it created. What are the main reasons for its creation. What is platform independence and how java is related to Internet and other programming languages like C++ and C#.
