commandButton with Java

you sure can

the easiest way is to have ..

<h:commandButton biniding = "#{myBean.myVar}"/>

then in your javacode you have

FacesContext facesContext = FacesContext.getCurrentInstance();Application application = facesContext.getApplication();

HtmlCommandButton myVar= (HtmlCommandButton) application.createComponent( "javax.faces.Button");

//with getter and setter

then you have myvar in your backing code
