Sequoia provides high availability and performance scalability for databases. It is is the continuation of the C-JDBC project. It provides transparent database clustering (partitioning, replication, etc.). It works with any Java application without code modification and with any database engine. It has been successfully tested with Tomcat, JBoss, JOnAS, WebSphere, MySQL, PostgreSQL, Apache Derby, HSQLDB, SAP DB, Oracle, DB2, Sybase, MS SQL Server, Firebird, and more.
Mandala is a Java library which eases the development of concurrent object-oriented applications by using the concept of asynchronous references. Mandala also provides remote asynchronous references in order to create distributed applications. Mandala is dynamic in that objects do not have to be specifically written to be accessed asynchronously (and remotely).
ProActive is a Java library for parallel, distributed, and concurrent computing as well as mobility and security in a uniform framework. It provides a comprehensive API and a graphical interface and is based on an Active Object pattern, a uniform way to encapsulate a remotely accessible object, a thread as an asynchronous activity, an actor with its own script, a server of incoming requests, a mobile and secure agent, and a component with server and client interfaces. It simplifies the programming of applications distributed over a LAN, clusters, an intranet, or Internet GRIDs.
MantaRay is a distributed, peer-to-peer, server-less communication and messaging solution for Java (JMS), C++, and .NET applications. It integrates with JBoss, WebLogic, and WebSphere and offers guaranteed delivery, security, and transactions. It supports the TCP, SSL, and HTTP protocols.
The IberAgents platform is a framework for component development in Java. It has facilities for Web service communication (SOAP), persistence to database or files, and interaction via the Web; thus providing an end-to-end solution for data management. It uses its own SOAP library, so it does not depend on Axis or Apache Soap.
