Well, I've been looking at this off and on for the past two months, and I've
finally been able to pinpoint when it happens, but I still don't understand
why. I've verified this behavior with both beta3c & rc0.
This happens when I have a structure I'd like to unmarshall which has a few
elements I'd like to ignore. To accomplish this, I add something like:
<structure name="abc" class="com.my.MyClass">
<value name="important" field="important" />
<value name="dontcare" />
</structure>
If I add a constructor of the form:
public class MyClass
{
private String important;
public MyClass( String s )
{
// Do nothing
}
...
}
Then everything works as expected (I get the "important" field, but the
presence of the "dontcare" field doesn't cause the unmarshalling to fail).
You seem to address this in your response from below, Dennis (You should only
get that message when you are using an object as a simple <value>). I guess
that's what I'm doing, but I still don't understand why this is required, or
why this constructor is required but never called.

Subject: Re: [jibx-users] Why does jibx always need a constructor from
java.lang.String?
This one puzzles me, Joshua. You should only get that message when you
are using an object as a simple <value>. Unless you specify otherwise
(using a <format>, or deserializer="xxxxx") JiBX needs the constructor
from String to create an instance of the object corresponding to the
text value seen in the input document. Yet you say the constructor is
not actually being used. Can you give more specifics of your binding and
data?
