< body >

private UIInput txtUser ;

public UIInput getTxtUser() {

return txtUser ;

public void setTxtUser(UIInput txtUser) {

this . txtUser = txtUser;

}

public void txtListener(ActionEvent e){

txtUser .setValue( "11111" );

System. out .println( txtUser .getValue().toString());

}

2. 在一�?/span> bean 中调用其�?/span> bean

FacesContext context = FacesContext.getCurrentInstance();

ValueBinding binding = context.getApplication().createValueBinding(

"#{uptBean}" );

uptBean bean = (uptBean) binding.getValue(context);
