Like this:

YourBean testBean = (YourBean)FacesContext.getCurrentInstance().getExternalContext()
               .getSessionMap().get( "yourBean");

or

    ELContext elContext = context.getELContext();
    context.getApplication().getExpressionFactory()
       .createValueExpression(elContext,"#{sessionScope.sessionValue}", String.class)
       .setValue(elContext, this.getSessionValue());
