Strange OJB error

[Vamsi Atluri <vk...@yahoo.com>]

Hello all,
 
We have an application that does broker.store() on about 20 tables in one go in a single transaction using a single broker instance. We are using OJB 1.0.1 on WSAD 5.1 using JDK 1.3.1. On and off I see this error happen:
 
org.apache.ojb.broker.core.proxy.ListProxyDefaultImpl not found in OJB repository.
 
Does this stand out to any body? It it so random, I cannot pin point what conditions are causing it. Why is OJB trying to find ListProxyDefaultImpl in the OJB repository?? Any help is greatly appreciated. Thanks.
 
Regards,
-Vamsi

You are the first one reporting this error message - seems OJB (or you) 
try to directly store an instance of this class. The class 
ListProxyDefaultImpl is used to enable lazy loading of 1:n and m:n 
references, thus something like this would cause this error:
...
List books = bookStore.getBooks();
broker.store(books);
...
Could you please post the whole stack trace of the error?

regards,
Armin
