I may be new to Hibernate but I've read post after post and document after document but for some reason my simple task does not work. Am I experiencing some odd dependency problem???

All I want to do is create a many-to-many relationship. Advise would be greatly appreciated. Changed names from basic event to person example with:

<hibernate-mapping>

<class name="adsea.dynosite.func.job.ServiceDO"
table="_job_service">
<id name="id"
column="_service_id"
type="java.lang.Long">
<generator class="sequence">
<param name="sequence">_job_service_id_seq</param>
</generator>
</id>
<property name="name" type="java.lang.String" column="_name" length="255"/>
<property name="price" type="java.lang.Double" column="_price"/>
<property name="loadLimit" type="java.lang.Integer" column="_load_limit"/>
<property name="minutes" type="java.lang.Integer" column="_minutes"/>
<property name="other" type="java.lang.String" column="_other" length="5000"/>
<set name="providerSet" table="_job_provider">
<key column="_service_id"/>
<many-to-many column="_provider_id" class="adsea.dynosite.func.job.ProviderDO"/>
</set>

</class>

<class name="adsea.dynosite.func.job.ProviderDO"
table="_job_provider">
<id name="id"
column="_provider_id"
type="java.lang.Long">
<generator class="sequence">
<param name="sequence">_job_provider_id_seq</param>
</generator>
</id>
<property name="name" type="java.lang.String" column="_name" length="255"/>
<property name="userId" type="java.lang.Long" column="_user_id"/>
<property name="reqdConfirmation" type="java.lang.Integer" column="_reqd_confirmation" not-null="true"/>
<property name="other" type="java.lang.String" column="_other" length="5000"/>

</class>

</hibernate-mapping>


I've built java classes to match. Get following error:
