To run a java program in Windows 10, we need first to install Java and then set up the environment variables. To do this, follow the following steps-

" Should you need to compile an OT/J program outside the OTDT, the following steps should enable you to use ANT for this task: download ecotj.jar you'll always find the latest version here in the column "Command Line Compiler" add it to your ANT runtime classpath (either place it in your ant_lib directory or provide the path by a -lib command line option to ant). in your build.xml set the property build.compiler to use the OTDT compiler in tasks, like that: "

"Community Dashboard Framework (CDF) is a project that allows you to create friendly, powerful, fully featured dashboards on top of the Pentaho BI server. Former Pentaho dashboards had several drawbacks from a developer's point of view. The developing process was awkward, it required know-how of web technologies and programming languages, and basically it was time-consuming. CDF emerged as a need for a framework that overcame all those difficulties. The final result is a powerful framework featuring the following: . It is based on Open Source technologies. . It separates logic (JavaScript) of the presentation (HTML, CSS) . It features a life cycle with components interacting with each other . It uses AJAX . It is extensible, which gives the users a high level of customization: . Advanced users can extend the library of components. . They also can insert their own snippets of JavaScript and jQuery code. CDF can be used: . As part of a Pentaho solution. This is the most common scenario. . In a standalone mode as an alternative to the Pentaho User Console . Integrated with Portlets, PHP applications, intranet portals and even desktop applications. "

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:

"The Apache Commons CLI library provides an API for parsing command line options passed to programs. It's also able to print help messages detailing the options available for a command line tool. "

Xtext - Language Development Framework With Xtext you can easily create your own programming languages and domain-specific languages (DSLs). The framework supports the development of language infrastructures including compilers and interpreters as well as full blown Eclipse-based IDE integration. While Xtext equips you with a set of sensible defaults, you can tweak every single aspect of your language with Xtext's powerful APIs. A comprehensive documentation as well as the vivid community will help you getting started in no time. And if that is not enough you can buy trainings, consulting or support contracts delivered directly by the committers.

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.

"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."

"Scalaz is a library written in the Scala Programming Language. The intention of Scalaz is to include general functions that are not currently available in the core Scala API. The scalaz-core module depends only on the core Scala API and the core Java 2 Standard Edition API. Scalaz is released under a BSD open source licence making it compatible with the licence of the Scala project. Scalaz 6.0.1 was released in June 2011, targeting Scala 2.8.1 and 2.9.0.1. "

Great website for begginers in java (and not only). It goes from the very beginning to intermediate topics and simple game development.

"An "executable" UML model is one with a behavioral specification detailed enough that it can effectively be "run" as a program. This can be extremely valuable in order to test and validate the model, independently of the one or more implementation platforms to which the system being modeled will ultimately be deployed. Or, in some cases, the model itself can actually be run as the production implementation, given an appropriate execution environment. There have been model execution tools and environments for years, even before UML. However, each tool defined its own semantics for model execution, often including a proprietary action language, and models developed in one tool could not be interchanged with or interoperate with models developed in another tool. A previous post described Stephen Mellor's quest of more than a decade to change this through OMG standards for precise UML model execution semantics and a UML action language. In 2008, this led to the adoption of the Foundational UML (fUML) specification, providing the first precise operational and base semantics for a subset of UML encompassing most object-oriented and activity modeling. The fUML specification still did not provide any new concrete surface syntax, however, tying the precise semantics solely to the existing abstract syntax model of UML. This meant that, in order to fully specify a detailed behavior in a UML model - say the effect behavior of a transition on a state machine or the method of an operation of a class - one still had to draw a very detailed, graphical activity diagram.

"Developers usually have their programs write log and debug information to the standard output during coding and testing. This results in a lot of text being printed to Eclipse's console view, often more than can be easily surveyed. Since at any given time, only a small part of this information is of primary interest to the developer, a tool which highlights specific lines or words can significantly increase the readability of this output. Grep Console allows you to define a series of regular expressions which will be tested against the console output. Each expression matching a line will affect the style of either the entire line or parts of it. For example, error messages could be set to show up with a red background, or integer values showing the state of a certain variable could be rendered in bold font. "

"Clojure functional programming language for JVM has powerful mind-bending features. The feature that interests me the first time is its ability to "execute data as code". As demonstrated here, were I define a function process that basically executes the symbol processor with whatever params : => (defn process [& params] (eval (cons processor params))) #'user/process "

"Quercus is Caucho Technology's 100% Java implementation of PHP 5 released under the Open Source GPL license. Quercus comes with many PHP modules and extensions like PDF, PDO, MySQL, and JSON. Quercus allows for tight integration of Java services with PHP scripts, so using PHP with JMS or Grails is a quick and painless endeavor. With Quercus, PHP applications automatically take advantage of Java application server features just as connection pooling and clustered sessions. Quercus implements PHP 5 and a growing list of PHP extensions including APC, iconv, GD, gettext, JSON, MySQL, Oracle, PDF, and Postgres. Many popular PHP application will run as well as, if not better, than the standard PHP interpreter straight out of the box. The growing list of PHP software certified running on Quercus includes DokuWiki, Drupal, Gallery2, Joomla, Mambo, Mantis, MediaWiki, Phorum, phpBB, phpMyAdmin, PHP-Nuke, Wordpress and XOOPS. Quercus presents a new mixed Java/PHP approach to web applications and services where Java and PHP tightly integrate with each other. PHP applications can choose to use Java libraries and technologies like JMS, EJB, SOA frameworks, Hibernate, and Spring. This revolutionary capability is made possible because 1) PHP code is interpreted/compiled into Java and 2) Quercus and its libraries are written entirely in Java. This architecture allows PHP applications and Java libraries to talk directly with one another at the program level. To facilitate this new Java/PHP architecture, Quercus provides and API and interface to expose Java libraries to PHP. The Quercus .war file can be run on Java application servers such as Glassfish, i.e. it can be run outside of Resin. This .war file includes the Quercus interpreter and the PHP libraries."
