The goal of Simple is to bring the power of simplicity to the world of server side Java. The primary focus of the project is to provide a truly embeddable Java based HTTP engine capable of handling enormous loads. Simple provides a truly asynchronous service model, request completion is driven using an internal, transparent, monitoring system.
This allows Simple to vastly outperform most popular Java based servers in a multi-tier environment, as it requires only a very limited number of threads to handle very high quantities of concurrent clients. Simple has consistently out performed both commercial and open source Java Servlet engines and has a fully comprehensive API that is as usable for experienced Java developers as it is for beginners. Best of all, Simple is completely free, and is released under the terms of the GNU Lesser General Public License, LGPL, which ensures its availability for use by open source and proprietary developers alike.
The XAware project provides real time data integration with a service-oriented flavor. XAware makes other tools and frameworks much more productive by hiding data complexity behind "XML views". XML views span any number of data sources, and can read data, write data, or transfer data between sets of sources, all within a distributed transaction.
The ActiveBPEL™ engine is a robust runtime environment that is capable of executing process definitions created for the Business Process Execution Language (BPEL) standard.
One of the biggest promises of Business Process Management was that the business people can model and execute their business processes without involvement from IT folks. This promise was kept in a simple workflow sceanarios by utilizing limited number of 'built-in' activity types of BPMS packages but once you face little more complex business process sceanarios providing transactional integration with existing software and complex interactions with human beings, this limited expression power make it hard to drag and drop process modeling, and finally it brings a huge help from software vendors or system integrators and write a lot of code that is making processes utterly inflexible downstream. That means, concurrent BPMS is extremely lack in something like 'Technical Abstraction' and 'Expression Extensibility'.
Project Open ESB implements an Enterprise Service Bus (ESB) runtime using Java Business Integration as the foundation. This allows easy integration of web services to create loosely coupled enterprise class composite applications.
The intention for this project is a very simple API to call different kinds of services (provider/technology). Crispy's aims is to provide a single point of entry for remote invocation for a wide number of transports: eg. RMI, EJB, JAX-RPC or XML-RPC. It works by using properties to configure a service manager, which is then used to invoke the remote API. Crispy is a simple Java codebase with an API that sits between your client code and the services your code must access. It provides a layer of abstraction to decouple client code from access to a service, as well as its location and underlying implementation. The special on this idea is, that these calls are simple Java object calls (remote or local calls are transparent).
OpenXava is a framework to develop easily business applications with XML and Java. Its virtue resides in the fact that the heart of our applications is XML instead of Java. For example, if you want a J2EE application that works with Teachers you only need
