Oh, to post what I'm doing I need to spend a lot of time explaining feridian,
which I'm not enough familiar with ;) I bet I can't explain what is going on
:(
I'm just trying to extend feridian with new packets, I created jibx mapping (I
altered it a bit to support collections instead of arrays, as before, and
exception was changed a bit
Exception in thread "Feridian - office.redwerk.com"
java.lang.NoSuchMethodError:

so it looks like changes I made were compiled, and this is not a
classpath-related issue )
The binding is:

// compare(reader);
}
}
everything works just fine, but If I try to use new class to parse XML, the
error occurs :(
Makes sence for you or may be you need to know some more specific
details/sources?
