Class JContainer

java.lang.Object
  org.objectweb.jonas_ejb.container.JContainer

All Implemented Interfaces:

Container

public class JContainer
extends java.lang.Object
implements Container

This class represents an EJB container. A container is where an enterprise Bean object lives. All beans from a same ejb-jar file are installed in a single container. For each EJB installed, the container provides a factory and makes it available in the JNDI name space. The JContainer basically manages a set of BeanFactory objects.
