    // Many JavaBeans
    BeanContextChildSupport[] beans = new BeanContextChildSupport[100];

    System.out.println("Number of children in the context: " + context.size());

    // Create the beans and add them to the context
    for (int i = 0; i < beans.length; i++) {
        beans[i] = new BeanContextSupport();
        context.add(beans[i]);// w  w w  .jav  a 2  s .co m
    }
    System.out.println("Number of children in the context: " + context.size());

    // Context now has 100 beans in it, get references to them all
    Object[] children = context.toArray();
    System.out.println("Number of objects retrieved from the context: " + children.length);
