Bear is a lightweight remote automation tool for Groovy/Java/JVM. It allows you to deploy projects, setup your cluster, and install software to your remote machines. It differs from other existing tools in that it uses a programmatic approach - your deployment is a regular Java class. It also uses static types, chained method calls, FP, and fluent programming techniques.
NW.ORM is a simple wrapper for accessing databases using hibernate in Java. It makes working with multiple databases easy. Aside from adding dependencies to your project and placing your hibernate configuration files in your classpath, no extra configuration is required. NW.ORM provides base classes for JPA-based class definitions. You can query using your method of choice. NW.ORM supports Criteria, HQL, and raw SQL.
The Arakhnê.org Foundation Classes (AFC) is a collection of Java libraries (based on Maven) that provides a collection of utilities that are not provided in the standard Java API. Many utility classes are provided: file filters, progress indicators, arrays, collections, VM utilities, text utilities, math tools (point, vector, matrix, shape, etc.), widgets for AWT, Swing, and Android, a platform-independent graphical API, and more.
Easy I18N is a library that integrates GNU gettext with the JVM's internationalization facilities. Existing Java APIs (MessageFormat, DateFormat, Locale) are used to provide a much easier API for building and maintaining applications and Web apps. It includes the ability to use normal message strings in your code, use xgettext to auto-extract translatable strings, leverage the GNU gettext system and associated tools to manage translations, work with date, currency, and numeric input/output, supports thread-local Locales for Web apps (or global for apps), and more.
JCabi is a collection of small, useful Java components. It includes a convenient static wrapper around SLF4J, a Sonatype Aether adapter, an Amazon Elastic Beanstalk Maven plugin for seamless deployment of artifacts, a Heroku Maven plugin, a Maven Log to SLF4J binding, and a few others.
Unlike other Java to Objective-C solutions, Java-Objective-C Bridge doesn't require any code generation of class stubs. It allows you to use any Objective-C libraries and frameworks from Java without having to write any native code. In addition to being able to use Objective-C objects, it allows you to pass Java objects to the objective-c runtime as delegates, so that you can write an entire Cocoa application in Java. The bridge provides 3 levels of abstraction. At the lowest level, it provides wrappers around the Objective-C runtime functions. At a slightly higher level of abstraction, it provides a procedural API to send messages to the Objective-C runtime. At the highest level of abstraction, it provides a Proxy class that serves as a wrapper around any Objective-C object that allows you to work with it in Java almost the same as if you were in Objective-C.
Funcito is a Java library which simplifies access to your favorite functional programming APIs by wrapping Java methods as the function-type objects defined in those libraries. Rather than creating another functional programming API, Funcito makes it easy to define function-type objects which wrap existing methods. As a result, your code has less noise and clutter of anonymous inner classes, annotations, etc. Your code remains safe for automated refactoring, since there are no String-based reflection or forced naming conventions. The supported frameworks are Google Guava, Jedi, Functional Java, Play! Framework 2, collections-generic, and Netflix RxJava.
