    json4java

    Very Compact Java Reader / Writer ( 12kb)

    I was i need of a json writer / parser which is - Compact. Libraries around there are way too big given the json spec and my usual need for a project. -Simply integrated as a simple jar. Dont want to force Maven dependency on projects. Could not find it so i wrote it. I dont claim its perfect , but should save some time for small / medium projecs. Json types are intuitively mapped to their Java counterparts : Map , List. I did not try all UTF16 encodings , but let me know i will fix it IF YOU GIVE ME A TEST CASE. ( input this , expect that ) Also floating point parsing for exponential notation can be slighly improved , does not bother on my projects. Android dev will like it to be as small as it can be i guess. Documentation in readme.txt

    lixa

    LIXA, LIbre XA, is a free and open source XA transaction manager

    LIXA (LIbre XA) is an open source and free Transaction Manager implementing the distributed transaction processing "XA specification" and "TX (transaction demarcation) specification" according to the X/Open CAE Specification. LIXA implements even XTA: XA Transaction API, an innovative API that implements XA transactional context passing among different applications. LIXA is a Transaction Manager but it's not a Transaction Monitor: this is the distinguishing feature of the project. LIXA technology enables every application container, like a web server or a shell, to become a two phase commit application server. The client/server architecture of LIXA allows many application containers to share a single LIXA (state) server: this is ideal when horizontal scalability is a must and many identical application containers must refer to a single transactional environment. LIXA can be used with the C, C++, Java, Python and COBOL programming languages.

    .Net Native Interface Library

    The best library to work with .Net Assemblies in any programming lang.

    The .Net Native Interface Library (DotNetNativeInterface) is a native programming interface which provides a way for programming languages such as C, C++, Fortran, Assembly, Pascal, Java, VB etc to interact with applications and libraries written in any of the .Net languages (such as C#, VB.Net etc). Programmers can use DotNetNativeInterface native methods to access .Net 3rd party libraries or .Net Framework Libraries without the need for registry entries, COM registrations or changes to the .Net libraries. The following examples illustrate when you need to use DotNetNativeInterface native methods: 1. You want to access and use .Net Framework Class Library in your application. 2. You want to access and use 3rd party .Net Libraries in your application. Competitive Advantages: 1. Access to .Net Framework Class Library. 2. No COM registration of .Net Libraries is required when deployed. 3. Allows any programming language to consume .Net libraries as if they were native code.

    30 Seconds of Java

    30 Seconds of Java

    Collection of reusable tested Java 21 compatible code snippets

    30 Seconds of Java is a curated collection of short, focused Java code snippets intended to teach small concepts quickly, similar to the popular “30 seconds of code” format in other languages. Each snippet is designed to be read and understood in under a minute, showing a single idea such as working with streams, handling optionals, manipulating collections, or doing common utility tasks. The repo targets both beginners who want bite-sized learning and experienced developers who just need a ready-made idiom without digging through docs. Because the snippets are standalone, you can copy them directly into your project or adapt them with minimal changes. The collection is organized and documented so you can browse by category and skill level. Overall, it’s a convenient library for learning modern, idiomatic Java fast and applying it right away.

    A-JLib

    A simple java lib with Swing widgets and other stuff.

    A simple java library with Swing widgets and other stuff. This library tries to simplify the development of Swing applications ... which is sometime a nightmare ! It contains the classes I developed during the Yapbam project in order to deal with the problems I encountered. This work is still under progress and some things may be changed in the future (especially some class names). The classes available here are quite stable and used in the Yapbam project. AJlib is also available through Maven GroupId: com.fathzer ArtifactId: ajlib javadoc is at https://javadoc.io/doc/com.fathzer/ajlib
