Hi,

I have downloaded "hibernate-2.1final.zip" after extracting jar file and appling to my hbm files .

My hbm looks like this : -

<class name="TCx1PtsiteT" proxy="TCx1PtsiteT" table="T_CX1_PtSite_T">
<composite-id>
<key-many-to-one name="tcx1PatientT" class="TCx1PatientT">
<column name="PatID" />
</key-many-to-one>
<key-many-to-one name="tcx1ParticipantM" class="TCx1ParticipantM">
<column name="Participant_ID" />
</key-many-to-one>
</composite-id>
</class>

It give me following Exception :-

INFO: Mapping class: com.ge.med.registries.acc_30.hibernate.TCx1PtsiteT -> T_CX1_PtSite_T
Exception in thread "main" java.lang.NullPointerException

since it contain compoiste-id .
whether this is BUG ...
