Cargo A common API to manipulate containers 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.
