Access Managed Bean Progmatically

Since
ValueBinding binding = application.createValueBinding and
context.getApplication().getVariableResolver().resolveVariable
are deprecated after jsf 1.2.

An uptodate approach is to utilize new lvalue feature of Class ValueExpression
(http://java.sun.com/javaee/5/docs/api/javax/el/ValueExpression.html)

Example. (Jdeveloper 11 help center, 2 Getting Started with ADF Faces)

Example 2-15 Setting a New Object on a Managed Bean
public static void (String expression, Object newValue) {
FacesContext facesContext = getFacesContext();
Application app = facesContext.getApplication();
ExpressionFactory elFactory = app.getExpressionFactory();
ELContext elContext = facesContext.getELContext();
ValueExpression valueExp =
elFactory.createValueExpression(elContext, expression,
Object.class);

//Check that the input newValue can be cast to the property type
//expected by the managed bean.
//Rely on Auto-Unboxing if the managed Bean expects a primitive
Class bindClass = valueExp.getType(elContext);
if (bindClass.isPrimitive() || bindClass.isInstance(newValue)) {
valueExp.setValue(elContext, newValue);
}
}
