Armin,
Thanks for your reply.
Here is a portion of my repository.xml. I am not sure
whether the missing attribute for
proxy-prefetching-limit causes the problem?
<descriptor-repository version="1.0"
isolation-level="read-uncommitted">
<!-- include all used database connections -->
&database;
<!-- include ojb internal mappings here -->
&internal;
Thanks,
Zhe
