I don't understand what is the problem? Before add a collection of events to the person class, i hadn't problem!
Please help me.

Please check events/Person.hbm.xml.

Maybe there's an invalid character or a misformed tag somewhere near line 14 as your error log states:

"""Error on line 14 of document : The content of elements must consist of well-formed character data or markup."""

Otherwise post your Person.hbm.xml.

-mj

I don't see anything,...
This is my Person.hbm.xml file:

<hibernate-mapping>

<class name="events.Person" table="PERSON">
<id name="id" column="PERSON_ID">
<generator class="native"/>
</id>

<property name="age"/>

<property name="firstname"/>

<property name="lastname"/>

<set name="events" table="PERSON_EVENT">
<key column="PERSON_ID"/>
<many-to-many column="EVENT_ID" class="events.Event"/>
</set>
</class>

</hibernate-mapping>

Thanks

Please add the declarations below on top of your mapping-file.

HTH, Maik
