JoSQL (Java Objects SQL) provides SQL capabilities for querying, ordering and grouping of collections of Java objects (POJOs). It allows a SQL statement to be applied to the collection of objects and the matching set returned, ordered and grouped.

MyBatis is a first class persistence framework with support for custom SQL, stored procedures and advanced mappings. MyBatis eliminates almost all of the JDBC code and manual setting of parameters and retrieval of results. MyBatis can use simple XML or Annotations for configuration and map primitives, Map interfaces and Java POJOs (Plain Old Java Objects) to database records. Every MyBatis application centers around an instance of SqlSessionFactory. A SqlSessionFactory instance can be acquired by using the SqlSessionFactoryBuilder. SqlSessionFactoryBuilder can build a SqlSessionFactory instance from an XML configuration file, or from a custom prepared instance of the Configuration class. Building a SqlSessionFactory instance from an XML file is very simple. It is recommended that you use a classpath resource for this configuration, but you could use any InputStream instance, including one created from a literal file path or a file:// URL.

COLA is the abbreviation of Clean Object-Oriented and Layered Architecture, which stands for "Clean Object-Oriented and Layered Architecture." At present, COLA has developed to COLA 4.0. COLA is divided into two parts, COLA architecture and COLA components. The meaning of architecture is the structure of elements. The COLA architecture was born for this purpose, and its core responsibility is to define a good application structure and provide the best practice of the best application architecture. Through continuous exploration, we found that a good hierarchical structure and a good package structure definition can help us manage the chaotic business application system. After many iterations, we have defined a relatively stable and reliable application architecture. Good application architectures all follow some common patterns.

JPOX was an Apache2 licensed standards-driven Java persistence implementation. It is replaced by DataNucleus http://www.datanucleus.org

UCDetector (Unnecessary Code Detector) is a Open Source Eclipse Plugin Tool. UCDetector finds unnecessary (dead) public Java code. It suggests to make code final, protected or private.

The ftp4j library implements a Java full-featured FTP client. With ftp4j embedded in your application you can: transfer files (upload and download), browse the FTP site (directory listing), create, delete, rename and move directories and files.

ObjectBuilder is a C++ CASE tool (CASE, refactoring, documentation generator). It lets you create, manipulate and navigate classes, class relations, class members and class methods at a high level of abstraction.

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.

Umple is technology for Model-Oriented Programming. It adds abstractions such as UML associations, attributes, and state machines to object-oriented programming languages such as Java, C++, PHP and Ruby. A developer can use Umple in one of several ways. They can start with a pure model, containing only classes, associations, attributes and state machines, and then gradually add methods in one of the base languages to the Umple code base. Alternatively a developer can start with a normal program in a language like Java, and add modeling constructs in very small increments, gradually moving their system from a code-centric system from a model-centric system. Either way, Umple provides top-quality code generation. Umple is being used, for real systems. In fact the Umple compiler itself was written in Umple. Any Java, C++ or PHP project could use Umple. The UmpleOnline web app provides a quick way to explore the Umple approach. It is at http://try.umple.org

A Java middleware API supporting broker-less, type+topic-based publish/subscribe and request/reply messaging for both intra- and inter-application, object-level communication. Broker-less: messages are transmitted directly between eBus applications. There is no message broker (i.e. server) in between. Type+topic addressing: eBus clients subscribe to a message class (type) and message topic, providing stronger typing than just topic-based subscriptions. Object-level communication: eBus delivers messages directly to client objects, not to a client process.

OpenBBS is an open and extensible blackboard system for the development of flexible workflows. The flexibility is achieved through adoption of the blackboard pattern. OpenBBS is modular and embeddable which makes it a lightwheight solution for workflows.

Object oriented reusable software classes designed to be used to construct larger software projects developed in multiple software languages.

The J2XB project aims at offering seamless Java and XML integration defined in Java. J2XB is special in that no Java code generation is involved. J2XB transform the development of Java and XML binding from Java code generation to XML Schema generation.

UMMF is an open-source implementation of UML-compatible meta-meta-model, for the purposes of reifying meta-model implementations and to provide a platform for building flexible model and meta-model transformation tools.
