Re: Problem with BeanUtils

[Bill Siggelkow]

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().

Hi all,
I'm trying to use BeanUtils (I have the same problem with PropertyUtils) to
read dynamically a bean property. But it does not work. I think I'm missing
some thing very impportant.
I have a bean wuith some properties(see below TypAbonne.java).
When I pass a bean instance of this classand the string "lecode"  to the
following methode :
String getLibelle(Object obj,String prop)
{
        return BeanUtils(obj,prop);
}
I receive a NoSuchMethodException:
When I try to debug the code I see that PropertyDescriptor array associated
with my class TypAbonne contains only two descriptors : one for the property
"class" and the other for the property "bytes" and there are no others
descriptor for the properties "lecode" and "lelibelle".
What's wrong in the code above ?
May be my class TypAbonne should satisfy some others conditions ?
Is it necessary to create a typAbonneBeanInfo and override the mthod
getPropertyDescriptors ?
Thank you a lot for your help.
