locally I setup a similar test. This test pass.
Did you correctly set the doctype instruction in mapping2.xml (e.g.
typo)?
Both settings work for my local test:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE descriptor-repository SYSTEM "repository.dtd">
<descriptor-repository version="1.0" isolation-level="read-uncommitted"
proxy-prefetching-limit="50">
...
/>
or
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE descriptor-repository PUBLIC
"-//Apache Software Foundation//DTD OJB Repository//EN"
"repository.dtd"
[
...
]>
<descriptor-repository version="1.0" isolation-level="read-uncommitted"
proxy-prefetching-limit="50">
...
/>
