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.

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.

Cargo is a thin wrapper around existing containers (e.g. J2EE containers). It provides different APIs to easily manipulate containers. Cargo provides a Java API to start/stop/configure Java Containers and deploy modules into them. It also offers Ant tasks, Maven 1, Maven 2, Intellij IDEA and Netbeans plugins. There's also a Java API to parse/create/merge J2EE Modules and deployment descriptors.

This project provides a Castor JDO-specific implementation of the Spring ORM module, allowing users to use Spring ORM as their preferred choice of dealing with the persistence aspects of their applications whilst using Castor JDO as underlying persistence provider.
