Drools is an enhanced Rules Engine implementation, ReteOO, based on Charles Forgy's Rete algorithm tailored for the Java language. More importantly, Drools provides for Declarative Programming and is flexible enough to match the semantics of your problem domain with Domain Specific Languages.
Jencks is a lightweight JCA container which is easy to deploy inside Spring to provide inbound and outbound messaging using APIs like JMS, JAX-RPC, JBI and JCA CCI as well as providing an XA based pooling mechanism for JDBC and easy integration of Geronimo's TransactionManager with Spring.
Development Status: Production/Stable, Development Language: Java
GeoTools is an open source (LGPL) Java code library which provides standards compliant methods for the manipulation of geospatial data, for example to implement Geographic Information Systems (GIS). The GeoTools library implements Open Geospatial Consortium (OGC) specifications as they are developed, in close collaboration with the GeoAPI, GeoServer and uDig projects.
Drools.NET is a Business Rules Engine (BRE) based on Charles Forgy's Rete algorithm. Developers can now exploit a powerful Rule Engine through a completely managed .NET code base! Drools.NET is based on Jboss Rules, and comes with all the features of that Rules Engine.
Lingo is a lightweight POJO based remoting and messaging library based on Spring's Remoting which extends it to support JMS. Lingo can support a wide range of message exchange patterns including both synchronous and asynchronous message exchange.
Lingo is an ideal technology to cluster your POJO services to achieve load balancing across many servers and automatic failover. Lingo is high performance and works great in server centric environments as it can work with JCA to cleanly integrate with thread, connection and session pooling as well as handing of transactions, retry and exception handling.
Mule is an Enterprise Service Bus (ESB) messaging framework. It is a scalable, highly distributable object broker that can seamlessly handle interactions with services and applications using disparate transport and messaging technologies.
