Spring Framework. Core Technologies. The IoC Container. Bean Overview. A Spring IoC container manages one or more beans. These beans are created with the configuration metadata that you supply to the container (for example, in the form of XML <bean/> definitions).
The JavaBeans component API extends the Java platform's Write Once, Run Anywhere capability to reusable component development. In fact, the JavaBeans architecture takes interoperability a major step forward — your code runs on every OS and also within any application environment.
