I am trying to set up a simple one-to-many relationship with hibernate and it errors out "ERROR impl.DatastoreImpl - Could not configure datastore from input stream"

I have narrowed it down to this section of the hbm.xml:

<set name="hcpcscodes" lazy="true">
<key column="HCPCS_BASE_ID"></key>
<one-to-many class="com.graysail.pgbadmecs.domain.HcpcsBaseDescription">
</one-to-many>
</set>

This mirrors the examples in the documentation with one key difference, mine doesn't work. Has anyone encountered this/fixed it before? I'm currently using hibernate 2.06.

Most likely this is something like a parser error or DTD violation. Can you see something in the logs like that? Have you tried using a recent Hibernate version?

2.0beta6 ? You should upgrade at least to the 2.0.3 version (2.1.1 is better) and try

I wish I could update to a newer version, but this is for a project already built on 2.06 so we can't really switch out versions now. I'll look into the possible DTD conundrum and post what I find.

Does the error occur at startup or only once you use the mapped object? How are you configuring your connection (pool). Please show your hibernate.cfg.xml file.
