This is a lightweightjava 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.
A Controlled Language Programming (CLP) compiler, runtime engine, and development IDE for writing software in a natural (but somewhat restricted) language that clearly represents the real world concerns and maps to a 3GL (Java/Groovy) for execution.
Peruser is a open-source lightweight knowledge application framework. Peruser speaks XML and RDF and is implemented in Java. Peruser code runs within Cocoon, as a standalone webapp, as console programs invoked through ant, or as embeddable java code.
jLips is a lightweightJava persistence container that implements database persistence through Java interfaces through a defined field naming scheme. Can be used with any JDBC database. jLips has a very small footprint and a simple interface.
NecJGui is an antennas design tool, interface for Numerical Electromagnetic Code. It allows easily making NEC input files, and viewing them in 3D. It also contains a version of the simulator, so it's complete IDE for full-wave EM simulation.
