MUSCLE (Multi User Server Client Linking Environment) is an N-way messaging server and networking API. It includes client-side networking APIs for various languages, including C, C++, C#, Delphi, Java, and Python. MUSCLE lets programs communicate over a network via streams of serialized Message objects. The included server program ("muscled") lets its clients message each other and store information in its server-side hierarchical database. The database supports flexible queries via hierarchical wildcarding, and "live" updates via a subscription mechanism.
The Bright Side Framework provides ready-to-use, high-level J2EE components which will help you quickly build business J2EE applications accessed by rich Java/Swing clients on HTTP. The components are loosely coupled, which allows you to pick only the one you need. The Remoting transparently encapsulates EJB calls inside HTTP. The List Of Values provides nice features for the reference data of all business applications. The Smart Value Object tracks the client modifications and manages the optimistic concurrency during client/server communication. The Remote Iterator allows a rich client to fetch the results of a SQL statement, block by block.
The Portal Foundation Classes is a J2EE 1.3 library for developing highly interactive portal applications. It builds on the same concepts as Swing but takes the unique nature of request/response into account, in contrast to similar libraries. Using this library, the developer can focus on creating valuable interfaces without spending too much time on fundamental functionalities like rendering, layout, or validation.
JaxMeXS is a parser for XML Schema, written in Java. Unlike Xerces or similar parsers, this one isn't written for validation of conforming instances, but for schema authors who like to use the schema information or extend the XML Schema language with private data. An excellent example is JAXB, the Java/XML binding specification.
JiBX is a framework for binding XML data to Java objects. It lets you work with data from XML documents using your own class structures. The framework handles all the details of converting your data to and from XML based on your instructions, and performs the translation between internal data structures and XML with very high efficiency while still allowing you a high degree of control over the translation process.
PicoContainer is a tiny embeddable container for Constructor Dependency Injection (CDI) Inversion of Control (IoC) Java components. There are implementations for Java, .NET, Ruby, and PHP. Simple components for PicoContainer do not have to extend, implement, or throw anything. They also do not ship with XML declarations.
