value="" does not mean anything to the JSF el parser, it can't make sense of that. You need to actually provide a static value there, as in value="Some Text" or bind it to a variable in your backing bean as in value="#{compteBancaireMBean.myVariable}" where myVariable corresponds to an actual variable in your compteBancaireMBean backing bean. This variable must follow the javabean conventions i.e. you must have
private Integer myVariable; //I use Integer here just as an example, you can use any core java type
public void setMyVariable(Integer myVariable){
this.myVariable = myVariable
}
public Integer getMyVariable(){
return this.myVariable
}
