So I think the problem is, that the CallMethod rule does not expect any parameters
since you have specified:
1. no parameters
2. there is no body text to retrieve the parameter value from
I guess it will help, if you specify
1. digester.addCallMethod("access/reader", "setReader", 1);
2. digester.addCallParam("access/reader", 0, true);
so that your RWClass instance will be taken from the stack to tell the
call method rule to invoke setReader(RWClass) respectively setReader(Object)
later on.
Hope this solves your problem!!!

CK

Betreff: [digester] interface and setter
I have a class that have 2 private attributes Reader and Writer who define
getter and setter methodes
I use an factory to instanciate attributes class. I define it like this :
<acces name="SuivitServices">
<reader classe="com.arso.trelaze.socle.persistance.RWClass"/>
<writer classe="com.arso.trelaze.socle.persistance.RWClass"/>
</acces>
I call factories for the reader and writer to instanciate the good class :
digester.addFactoryCreate( "acces/reader",
"com.arso.trelaze.socle.persistance.ReaderFactory"
);
It works perfect I get an RWClass who implement both the reader interface
and the writer interface.
But when I try to call the setter void setReader(Reader reader) with the
rule :
digester.addCallMethod( "acces/reader", "setReader", 0 );
I had the following error :
java.lang.NoSuchMethodException: No such accessible method: setReader() on
object: com.arso.trelaze.socle.persistance.RWClass

I think it was an introspection error : it try to find a void
setReader(RWClass reader) and don't find it but how could I do to make
digester calling the good setter ?
I try to define it has void setReader(Object reader) but I had the same
error.
I am new to digester so sorry if it is an evidence for you.
thanks
Nicolas
