A tutorial on how to create a dynamic web project in eclipse

"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."

I am working on a web site that will help students practice their Scala programming skills. As I labored along, writing my JSF app code, I thought "this is silly-why not practice Scala at the same time?" But I like JSF and wasn't ready to jump to Lift or Vaadin. With Eclipse, this isn't all that hard. Install the Java plugin. Make a dynamic web project in the usual way, using the Java EE perspective. Then, switch to the Scala perspective, right-click on the project, and, if all planets are aligned correctly, you will get a menu item "Add Scala nature". (If they are not, see here for a manual approach.) Add your managed beans as Scala classes. Finally, switch back to the Java EE perspective, select the project properties, and add the Scala library JAR as a Java EE module dependency. But I like NetBeans and wasn't ready to switch to Eclipse. (Unfortunately, JSF 2 support in Eclipse is pretty minimal, the Glassfish integration is a bit flaky, and the Scala plugin has very little usable code completion.) NetBeans doesn't let me add a "Scala nature" to a web project. If I add Scala files to the project, I can edit them with the Scala editor, but they just get copied to the WAR file, without any compilation. I had one look at the Ant scripts for a Scala and a web project and decided that I wasn't going to figure out how to merge them. This blog shows how you can use Maven to make a mixed Scala/Java project in NetBeans. So I gathered up JSF and Scala pom.xml files from here and here, cut out the considerable crud from the JSF POM file that was probably meant for supporting Tomcat, and merged the results to the best of my ability-see below. You use the usual Maven directory structure, but with a src/main/scala directory instead of src/main/java:

Provide mechanisms for integrating Java security providers into Eclipse: Applications that need to implement security related functionality require cryptographic services upon which to build. Java provides the Java Cryptography Architecture (JCA) as a mechanism for installing implementations of several interfaces used for cryptography, including MessageDigest, Signature, KeyStore, Certstore, and more. In a typical Java application, these implementations reside in the extensions directory of the JRE. In a dynamic Eclipse application, the appropriate packaging mechanism is in Eclipse plug-ins. The goal is to allow JCA to be used in an Eclipse environment while maintaining the programming model of the JCA subsystem. A related goal is to expose the configuration of the JCA system via an Eclipse-based user interface, allowing authorized users to inspect and modify the Security object.

"Libra is an open source project under the Eclipse Web Tools Platform Container Project. It provides standard tools for OSGi Enterprise application development and in particular tools that integrate the existing WTP and PDE tooling so that OSGi Enterprise applications can be developed with both tooling at the same time. Libra also will enable users to work with tools for better experience in the Server-Side Equinox scenario. The goals of the project are: Providing tools for creation of deployable artifacts for application servers implementing the OSGi Enterprise specification, e.g. wizard for creating new Web Application Bundle projects. Providing tools for converting existing Java EE deployable artifacts to OSGi Enterprise deployable artifacts, e.g. wizard for converting Dynamic Web projects to a Web Application Bundle projects. Contributing tools for editing and validation of the metadata of OSGi Enterprise artifacts, e.g. extension of the PDE Manifest Editor for editing manifest headers that are specific to Web Application Bundles. Developing OSGi server adapter, providing basic implementation of configuring an OSGi-based application server, starting it and deploying OSGi enterprise artifacts. This server adapter should be customizable and extensible by adopters. Delivering tools that improve the experience of developing Server-Side Equinox applications. Extending the tools in scope, so adopters can apply them depending on their own application model."

"Blueprint provides a dependency injection framework for OSGi and was standardized by the OSGi Alliance in OSGi Compendium R4.2. It is designed to deal with the dynamic nature of OSGi, where services can become available and unavailable at any time. The specification is also designed to work with plain old Java objects (POJOs) enabling simple components to be written and unit tested in a JSE environment without needing to be aware of how they are assembled. The Blueprint XML files that define and describe the assembly of various components are key to the Blueprint programming model. The specification describes how the components get instantiated and wired together to form a running module. The following documentation covers the 80:20 usage of Blueprint. For further details, please refer to the OSGi Compendium R4.2 specification."

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
