       Body:
Ok that was a middlegen issue. 
Previously the generated xml was  -

<id
		generator-class="assigned"
		name="channelId"
		type="int"
		column="channel_id"
		not-null="true"
		length="3"
	>

Changed the template in hibernate plugin for middlegen to generate it with  " />" 

Now next error - The ant task and the xml file are otherwise same.
