Open Source Java Object Oriented Software

SMC takes a state machine stored in a .sm file and generates a State pattern in 14 programming languages. Includes: default transitions, transition args, transition guards, push/pop transitions and Entry/Exit actions. See User Manual for more info.

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

The UCL MDA Tools are lightweight Model Driven Architecture tools developed at University College London. They include a JMI generator implemented using the velocity template engine, an OCL type checker, and a parser for textual MOF models.

jCompany Full-Stack Framework - Community Version. Hyper-produtive Full Stack Solution for Java EE Open Source Development.

ASTGen automatically generates implementations of Composite pattern hierarchies of data objects from a simple, one-file description of the class hierarchy. ASTGen is written in and generates code for Java. Includes an Ant task.

Provides possibility to adapt the interface of tested class. Enables to set a state of the class while writing tests by accessing the members that are not usually accessible.

Bluprint is an Agile-MDA code generator. It is a fuss-free tool supporting code generation from UML modelling tools. It supports model/code merging so engineers can easily extend and maintain generated code. Bluprint has been developed using itself.

The Catalsyt Framework is a refinement on the MVC framework. It provides greater focus on user business workflow rather than application workflow. It's goal is to enable business analysis and developers to work closer.

CHAMELEON is a declarative framework for tailoring adaptable Java applications for resource-constrained devices and can be used for tackling a form of adaptation to the execution context.

A lightweight ORM and SQL schema generator meant as a simpler alternative to Hibernate, etc. with the goal of bringing Rails-like functionality and rapid development to Java. Operates on plain Java classes.

Component (library, framework) refactoring may affect existing applications, where the client code used previous component versions. Our tool preserves applications binary-compatible by generating an adaptation layer out of change history.

An architecture description language (DiaSpec) supports the description of components of a given distributed computing area. From these descriptions, DiaGen generates a dedicated programming framework to support distributed application development.

Domain Specific Language (DSL) for Domain Modelling with the following characteristics: Java Like Language, Entities and relations modelling , Java Code Generation, Query automation

Fides is an extensible enterprise library for .NET 2.0 upwards and Java, containing a Object Relational Mapping framework and geared for simplicity and productivity.

The Generic Analyzer is a framework in Java that is designed to allow users to build, quickly and easily, compilers and interpreters without the need to implement all the complex steps of a translator.

The power provided by OWL reasoning engines can be translated into Java applications and vice versas with this framework. A binding among OWL and Java concepts has been done in order to incorporate the semantic features of OWL into Java.

JCommons provides generally re-usable Java tools and components. Some things included are: code generation, data and object conversions such as EDI to XML, visualizing object instances as FreeMind mindmaps and a framework for generating factories.

JDBL is a simple and flexible layer for moving data between Java objects and a relational database. It allows for direct, elegant use of SQL without the tedium of JDBC.

JUndo is a declarative object-oriented programming language with functional, and intensional programming characteristics. Applications include multi-level undo and sophisticated error recovery. See http://verdantium.blogspot.com/

Runtime library for the JUndo language. See http://verdantium.blogspot.com/

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.

Java-XML Binder (JXB) is a lightweight and easy to use Java-to-XML and XML-to-Java Mapping Tool. Mapping Rules should be configured through Java Annotations, you do not need any configuration files. JXB supports Objects of any complexity.

The Java/RTR Project address the development of soft real-time code in Java, mainly using the RTR Model and the Java/RTR programming language. It uses the RTSJ specification as main API, and only works on plataforms that have support to it.

Javast is a Java API for creating an Abstract Syntax Tree of java source code (the equivalent of an XML DOM) in memory and then writing this to a file or bytestream as formatted source code. It is mainly useful for java code generation.

Extendable general purpose DB framework. JugglerDB started out as a simple source code generation interface, to create Java DAOs for databases. At a certain point we decided to extend its usage to perform many other tasks. We decided to go ahead and deve
