Apache ESME (Enterprise Social Messaging Environment) is a secure and highly scalable microsharing and micromessaging platform that allows people to discover and meet one another and get controlled access to other sources of information.
You can hardly turn a web page these days without seeing a story that describes how people are using social networks, whether it is Twitter, Facebook or some other service to develop and build their personal communities.
When solving problems, how useful might it be if a user was able to tap into the collective knowledge of her peers or surrounding groups of people with whom she might naturally network in the workplace setting? How much quicker and with greater precision might she be able to solve daily problems? What if there was a communications mechanism that takes the best of what services like Twitter offers and co-mingled that with readily recognizable business processes? That solution is Apache ESME.

A Scala ORM and DSL for talking with Databases with minimum verbosity and maximum type safety
Write compiler validated statements.
Squeryl statements that pass compilation won’t fail at runtime. Refactor your schema as often as is required, the Scala compiler and your IDE will tell you exactly which lines of code are affected.
Never repeat yourself
The Composability of Squeryl statements allows you to define them
once and reuse them as sub queries within other statements.
Write declaratively
Write as declaratively as SQL, only with less boilerplate. SQL’s declarativeness is preserved, not encapsulated in a lower level API that requires imperative and procedural code to get things done.
Explicitly control retrieval granularity and laziness
A significant part of optimizing a database abstraction layer is to choose for every situation the right balance between fine and large grained retrieval, and the optimal mix of laziness and eagerness. Data retrieval strategies are explicit in Squeryl rather than driven by configuration like current generation Java ORMs read more
Scalate is a Scala 2.8 based template engine for generating text and markup which can be used in the following frameworks and environments:
* stand alone in any JVM or as a Servlet Filter in any Java in a web application
* with JAXRS with Jersey
* in the Play Framework via play-scalate
* in Apache Camel for transforming messages and templating
* to generate your static or semi-static website
Scalate supports the following template formats
* Mustache which is a Scala dialect of Mustache for logic-less templates which also work inside the browser using mustache.js
* Scaml which is a Scala dialect of Haml and is very DRY for generating HTML / XHTML
* Jade which is an even more DRY dialect of Scaml for HTML / XHTML markup generation
* SSP which is like Velocity, JSP or Erb from Rails
Scalate also has a powerful web console and command line shell which includes converters from JSP or HTML to Scalate
Still confused? Check out which template engine is right for me, why Scalate or how Scalate compares to JSP or Lift
Enterprise Social Messaging Environment (ESME) is a secure and highly scalable microsharing and micromessaging platform that allows people to discover and meet one another and get controlled access to other sources of information, all in a business process context.
You can hardly turn a web page these days without seeing a story that describes how people are using social networks, whether it is Twitter, Facebook or some other service to develop and build their personal communities. In business, we increasingly see blogs and wikis demonstrating utility in problem solving and communications but the real time nature of business process problem solving largely remains untouched by social networking tools. Existing services, while attractive do not scale well and have proven unreliable. This is unacceptable to business which must be 'Always On' and able to support people in their daily working lives. Such applications must therefore be scalable and reliable but also provide a lot more.
When solving problems, how good might it be if a user was able to tap into the collective knowledge of her peers or surrounding groupsof people with whom she might naturally network in the workplace setting? How much quicker and with greater precision might she be able to solve daily problems? What if there was a communications mechanism that takes the best of what services like Twitter offers and co-mingled that with readily recognizable business processes? That solution is ESME.
The point of "Graham Hacking Scala" is to share with you my knowledge of and experience with the Scala programming language. The blog will contain everything from introductions to basic features through to in-depth analysis of complex techniques and problems. When I make mistakes, you will learn from my mistakes. When I discover cool features, you will learn about them, too.
scalaxb-appengine is a RESTful API to run scalaxb over the web. It's implemented using n8han/Unfiltered and the full source is available on eed3si9n/scalaxb-appengine.
scalaxb-appengine came into being because I didn't know how to deploy a command line application written in Scala. Greg kindly suggested that I turn scalaxb into a web service, so I did. I guess I always thought about the possibility of making it into a web app, but this gave me a perfect opportunity to seize the moment and write a web app in Scala.
Scalaz is a library written in the Scala Programming Language. One mandate of the library is to depend only on the core Scala API and the core Java 2 Standard Edition API. The intention of Scalaz is to include general functions that are not currently available in the core Scala API. Scalaz is released under a BSD open source licence making it compatible with the licence of the Scala project.
Sweet is a web application framework for building dynamic web content that runs on any Java servlet server. The framework is made with Scala, a more advance and easier to write programming language compared to Java. Since Sweet applications can run on a Java Virtual Machine, it can take advantage of all the Java libraries, servers, and large communities.
Our visions and goals for Sweet is SWEET itself:
* Simplicity - Sweet needs to keep complex things simple.
* Works - Sweet needs to be practical and functional.
* Efficient - Sweet needs to be efficient.
* Extensible - Sweet needs to be extensible by developers.
* Testable - Sweet needs to be testable.
The Play framework makes it easier to build Web applications with Java
Finally a Java framework made by Web developers. Discover a clean alternative to bloated enterprise Java stacks. Play focuses on developer productivity and targets RESTful architectures.
pinky is a Scala REST/MVC glue web framework built on top of Guice and Guice Servlet. Pinky provides out-of-the-box support for dealing with forms, domain objects, jdbc and rss/xml/json/html content types
Scala Pages (SCP) is a lightweight web framework developed in the Scala language. It is intended for developing Scala web applications; it is released under the Apache 2 license. SCP provides an API that is familiar to Java programmers. It is built on and closely aligned to the Servlet API. It can be learned quickly by anyone familiar with Java web development. The SCP Scala web framework is build around a text-oriented template engine. Dynamic web pages are either generated from templates or from Scala code. Templates can be HTML-templates, XML-templates or any other text format, such as CSV, JSON, etc. Because SCP neither uses DOM nor SAX parsing, memory and CPU requirements are moderate. SCP makes use of XML processing instructions instead of custom tags.
We are attempting to build a scala compiler plugin to auto-generate avro classes based on some simple definitions. This plugin is for the Scala 2.8 compiler, and for the Avro 1.3.0 runtime.
ScalaCheck is a powerful tool for automatic unit testing of Scala and Java programs. It features automatic test case generation and minimization of failing test cases. ScalaCheck started out as a Scala port of the Haskell library QuickCheck, and has since evolved and been extended with features not found in Haskell QuickCheck.
EJBs in Scala schreiben
Was spricht eigentlich dagegen, eine EJB in Scala zu implementieren? Um diese Frage zu beantworten, habe ich ein Demo-Projekt aufgesetzt, in dem ich zwei EJBs in Scala implementiere.
Spde is an offshoot of the Processing environment to support sketches written in Scala, a powerfully object-oriented and functional language.
In contrast to the PDE, Spde is a deconstructed toolkit. For starters that means you bring your own editor and Spde will compile and run a sketch whenever you save it — that’s one option. The entire process is controlled by Scala code you can use or override. This structure should make Spde easy to extend and customize. But who knows, for now it is just a scrappy little thing with big ideas.
A tool for testing Scala and Java software
OSI Certified Open Source Software
ScalaTest is a free, open-source testing tool for Scala and Java programmers. It is written in Scala, and enables you to write tests in Scala to test either Scala or Java code. It is released under the Apache 2.0 open source license.
Because different developers take different approaches to creating software, no single approach to testing is a good fit for everyone. In light of this reality, ScalaTest is designed to facilitate different styles of testing. ScalaTest provides several traits that you can mix together into whatever combination makes you feel the most productive.
sbt is a simple build tool for Scala projects that aims to do the basics well. It requires Java 1.5 or later.
Features
* Fairly fast, unintrusive, and easy to set up for simple projects
* Configuration is done in Scala
* The default source directory layout is the same as maven's so you can always switch to maven should you need/want to
* Regardless of what sources you have added, changed, or removed, sbt should (in theory) recompile the right sources using information extracted from compilation with a compiler plugin
* Supports ScalaCheck, specs, and ScalaTest.
* Can generate documentation with scaladoc
* Packages jars (classes, sources, or api docs)
* Can start the Scala interpreter with the right classpath (dependencies and compiled classes)
* Multiple project/subproject support
* Parallel task execution, including parallel test execution
* Dependency management support: basic inline declarations, configuration with Maven (partial support) or Ivy, or manual management.
ScalaModules aims at Scala-based OSGi development. The mission of ScalaModules is to employ the power of the Scala programming language to ease OSGi development. Of course using Scala for OSGi will itself be beneficial, because of the great simplifications Scala brings compared to Java. But ScalaModules will also make use of the additional possibilities offered by Scala, mainly the chance to create a Domain Specific Language. Therefore with ScalaModules your code will be more intuitive and concise as well as less verbose and less involved compared to Java-based OSGi development.
