Athena Framework for Java is a full fledged enterprise object-relational mapping (ORM) framework that employs metadata as mapping configuration. It greatly simplifies Java Web application development by removing the requirement of manual mapping and manual database schema updating. In addition to features like Java object persistence, powerful EJBQL querying execution, and comprehensive code generation, Athena has built-in support for multi-tenancy, which enables developers to build cloud applications easily. Athena can be easily integrated with other libraries like Struts or Spring to provide full stacks of service.
CloverETL is Java-based tool/framework for data integration and creation of data transformations. It is component based and follows the concept of transformation graphs which consist of individual nodes/components performing simple (or complex) operations on data. Any transformation can be defined as a set of interconnected nodes through which data flows. CloverETL can be used as a standalone application or be embedded into a larger project.
Contracts for Java (Cofoja) adds contract programming support to Java through simple yet powerful annotations: @Requires, @Ensures, @Invariant, and @ThrowEnsures. Contracts are inherited from interfaces and superclasses and can be enabled selectively during development then disabled for release.
GAMF is a framework that allows developers to focus on system specific components when building managers for controlling a target system's configuration parameter in an autonomic manner. GAMF provides autonomic control components which are based on the autonomic management cycle (see Kephart and Chess). The generic control components comprise monitoring facilities (event generation), managing of monitoring data (thread-safe provision and filtering for events), and scheduling of metric extractions or policy evaluations (at regular intervals, or at the occurrence of a specific event, or arbitrarily). In addition to the generic control components, GAMF provides abstract system specific control components which can be easily extended and customized.
Icwri is a lightweight, very simple, service-oriented Java built-in script. It can help Java developers build some application interfaces in a service-oriented style. It can also help non-technical people join the development team to write their own application scripts to enforce business rules and decisions. Icwri service providers and consumers can be either Icwri scripts or Java classes. An Icwri script can run all alone, but the primary purpose of Icwri script is to have an assistant language of Java. It can run on any system with JDK/JRE 1.5 or above installed. It does not support Java SE 6 Script Engine because of the service-oriented design and the requirement to support Java SE 1.5 users.
