Enterprise Object Broker (EOB) is an application server that transparently distributes Java objects via their interfaces. It makes no distinction between Local and Remote objects. Because of these features, it is not J2EE compliant. The developer builds beans that implement normal Java interfaces and the deployer decides where the beans are in a cluster of servers. Apache's AltRMI is used in place of RMI. It publishes plain interfaces locally and remotely. The interfaces do not have to extend the java.rmi.Remote interface. Methods do not have to throw RemoteException. AltRMI delivers remoting for Java. EOB sits on top of Apache's Avalon-Phoenix server platform.
PicoContainer is a tiny embeddable container for Constructor Dependency Injection (CDI) Inversion of Control (IoC) Java components. There are implementations for Java, .NET, Ruby, and PHP. Simple components for PicoContainer do not have to extend, implement, or throw anything. They also do not ship with XML declarations.
