I found the problem. The Object passed to getLibelle was in fact a String.
What happen is the following :
- before passing the object (TypAbonne ) to getLibelle I put it in a
Collection in a ActionForm property,
- then I read this collection in the following way :
Object options[] = BeanUtils.getArrayProperty(form, liste);
The options array is filled with a list of String(s) (my TypAbonne converted
to String :[EMAIL PROTECTED]).
- Then I pass the options array element to the getLibelle method.
Thanks to all of you for help !

Objet : Re: Problem with BeanUtils
First of all, I assume that you are calling the getProperty method of
BeanUtils -- Are you sure that the object you are passing is an instance
of your class (TypAbonne) -- from what you indicated it sounds like it
is actually a String -- java.lang.String has two "getter" methods --
getClass() and getBytes().
