    Java Dynamic Component Framework

    This is a lightweight java dynamic component framework

    This lightweight dynamic component framework, implemented in Java in a first time uses no code generation at all but uses only contracts. Contracts are expressed using simple software mechanism as interfaces and/or reflection (from middleware to application). A single small jar hosts the code dedicated to data, event and services management over the network, using contracts, reflection and generics. The main goal of the Java Dynamic Component Framework (jdcf) is to simplify the writing (and reuse) of individual Java components, parts of distributed networked application. The model of the application is described in an XML file. The components are pure Java classes file using a pure Java middleware. Each component may be packaged in a jar or several related components may be packaged together. Component migration over the network is planned. Go to the Wiki to have an overview.
