This depends on where you want to call the code.
From a backing bean you best get access to the AM via this code:
     * Get FacesContext.
     * @return FacesContext
    public static FacesContext getFacesContext()
        return FacesContext.getCurrentInstance();
     * Method for taking a reference to a JSF binding expression and returning
     * the matching object (or creating it).
     * @param expression EL expression
     * @return Managed object
    public static Object resolveExpression(String expression)
        try
            FacesContext facesContext = getFacesContext();
            Application app = facesContext.getApplication();
            ExpressionFactory elFactory = app.getExpressionFactory();
            ELContext elContext = facesContext.getELContext();
            ValueExpression valueExp =
                elFactory.createValueExpression(elContext, expression, Object.class);
            return valueExp.getValue(elContext);
        catch (Exception e)
           ;// log you message here
        return null;
     * Get application module for an application module data control by name.
     * @param name application module data control name
     * @return ApplicationModule
    public static ApplicationModule getApplicationModuleForDataControl(String name)
        return (ApplicationModule) resolveExpression("#{data." + name + ".dataProvider}");
    }If you are in an application module ue the code from above:
this.getDBTransaction().isDirty()May be you should implement a method in you application module like
public boolean isDirtyTransaction()
return this.getDBTransaction().isDirty();
}which you then can call declarative in an EL.
