Réf. : AW: [digester] interface and setter
I try your solution but I still have the same error
"java.lang.NoSuchMethodException: No such accessible method:..."
With :
Class [] params = {com.arso.trelaze.socle.persistance.Reader.class};
digester.addCallMethod( "acces/reader", "setReader", 1, params );
digester.addCallParam( "acces/reader", 0, true );
The error occurs even if I specify our not the params kind.
At the moment I found an alternative which work. I use
digester.addSetNext( "acces/reader", "setReader" ); rather than an
addCallMethod . It is a fonctionnal solution but not really elegant.
So if some one have a better way ...

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

Re: Réf. : AW: [digester] interface and setter
Posted by robert burrell donkin <ro...@blueyonder.co.uk>.
i suggest that you check that the parameter type matches exactly the
method call signature: the CallMethodRule is very particular about the
type parameter.
