Re: [jibx-users] nable to access binding information, after successful binding?

[Dennis Sosnoski]

Can you see the field "JiBX_bindingList"? It gets added at the same time 
as the methods, but this is what the BindingDirectory method is failing 
to find.

I don't know of anything else that could cause this problem. A couple of 
things you can try in order to clarify what's going on: Step into the 
BindingDirectory code to inspect the actual Customer class that's been 
loaded, and run this standalone (outside of the IDE, assuming you're 
experiencing the problem when you try and run within the IDE). Also, try 
renaming the class file that's been modified by the binding compiler and 
see what happens - if you're right that there's only one instance, this 
should cause a different kind of failure, with ClassNotFoundException.

Dennis,
Thanks for your reply.
I am sure that I have just one class I am working
with.
I just run the search. Any other ideas how to resolve
it?
I can actually see the added methods to the class from
the jdeveloper
but when I run it I get that error?
I have spend couple of days trying to resolve it.
What would be your suggestion on correct approach?
Thanks.

This has happened before for a developer (I think also
using JBuilder, 
though I can't find the email) when they actually had
two sets of 
classes they were working with due to different
classpaths. One set of 
classes were modified by the binding compiler, but not
the set they were

actually trying to run. I'd strongly suspect the same
thing is happening
for you.

Hi,
I am not able to get the simplest test to work :(
   

and would appreciate
 

your help.
I am able to successfully bind and then when I run
   

test it fails on
 

ibf = BindingDirectory.getFactory(bin,target);

What gives? I must be doing something fundamentally
   

wrong but I have
 

searched the list and did not find anything on the
   

subject.
 

I know that methods got successfully added to the
   

class ....
 

Thanks for taking the time ...

this is an error:
