EnterAccess
Full JAVA JDBC Interface to MS Access using Jackcess
This JDBC interface serves as a full JAVA interface to MS Access files. It was developed to support the Software-Independent Archival of Relational Databases (SIARD) of the Swiss Federal Institute. It is based on the project Jackcess for accessing MS Access files and makes use of the project H2 for parsing SQL. It is an alternative to the JDBC interface UCanAccess, whose metadata and type support and very limited SQL for DDL and DML queries could not be adapted for the purposes of SIARD. Currently EnterAccess queries are limited to a single table. All DML and DDL queries are limited by the capabilities of Jackcess, which is good at reading a database and weak on creating a view, creating foreign keys, or modifying a schema. -

Essentials
General purpose utilities and hash functions for Android and Java
Essentials is a lightweight collection of high-performance utility classes designed to enhance standard Java and Android development without introducing heavy dependencies. The library focuses on providing efficient data structures and helper utilities that often outperform equivalent components in the standard Java API. It is intentionally minimalistic and is not positioned as a full framework, but rather as a focused toolkit that fills common gaps developers encounter in everyday projects. Essentials emphasizes speed and low footprint, with components such as LongHashMap delivering measurable performance improvements over standard implementations. The library is compatible with both Android and standard Java environments, making it broadly usable across platforms. Overall, Essentials serves developers who want faster and more convenient core utilities without adopting large libraries like Guava or Apache Commons. -

EventBus
The no.1 event library for Android
EventBus is an open-source library for Android and Java that uses the publisher/subscriber pattern for loose coupling, enabling central communication to decoupled classes with just a few lines of code. It simplifies communication between Activities, Threads, Services and other components while also simplifying code, eliminating dependencies, and overall improving app development speed and quality. EventBus offers several advanced features, such as jump start, delivery threads, subscriber priorities, and many others. It is specifically optimized for high performance and is small at just ~60k jar. It's been proven by numerous apps with more than a billion total installs. -

You know the component scanning feature of Spring? You'll love this: component scanning as easy as select(javaClasses()).from("your.package").returning(allAnnotatedWith(YourAnnotation.class)). Can support any language running on the JVM. ---------- eXtcos is now also available from Maven Central. To include it into your Maven project just add this dependency: groupId: net.sf.extcos artifactId: extcos version: 0.4b Unfortunately Sourceforge doesn't support XML snippets in the description, so you'll have to build it yourself if needed. ----------- To read the user manual click the website link below.

External Java Command Control
Send commands from the command-line to your running application.
Moved to GitHub https://github.com/fedups ExCon is a small Java class (a runnable Jar file, “sender”) that you run whenever you need to send a command to your application. Your application needs to include the ExCon “receiver”. The receiver accepts the commands from the ExCon sender and processes them. Since the receiver runs within you application it can access all of your application’s classes and resources. -

FXWindowFramer
A JavaFX library to repaint your Applications window frame.
Most developer’s wish list probably hosts the idea of exploring new ways of decorating his/her applications window... Of course, preferences of current OSes do propose a few options, but some may want more, or different choices, would it just be to frame their apps with their own uniform “branded” style. FXWindowFramer is a quite simple JavaFX library, which may be used to change the look&feel of a JavaFX application (applying just a few cosmetic changes through CSS definitions), or, as a starting point, to investigate more advanced alternatives... To keep things simple and the prototype easy to understand, FXWindowFramer only touches the application window frame (borders and nameplate), and only supports, as such, desktop applications that do not need resizing. The goal is : Keep the painting intact, but change that frame, keeping it as simple and close to usual JavaFX initialization as possible! -
