Nope .. it didnt work. Does this need some property in persistence.xml also ?
My new entity looks like this now
CampaignTarger.class
@ManyToOne(targetEntity=Campaign.class, fetch = FetchType.LAZY )
@JoinColumn(name = "campaign_Ref" ,nullable=true)
@ForeignKey(deleteAction=ForeignKeyAction.NULL)
private Campaign campaign ;
Campaign.class
@OneToMany(targetEntity=CampaignTarget.class, mappedBy = "campaign",
fetch=FetchType.LAZY )
private Collection<CampaignTarget> campaignTargets;
This is the complete stacktrace

Persistence Unit looks like this in xml
<persistence-unit name="imagingDS" transaction-type="JTA">
<jta-data-source>imagingDS</jta-data-source>
<properties>
<property name="openjpa.jdbc.DBDictionary"
value="oracle(UseGetBytesForBlobs=true,maxEmbeddedBlobSize=-1,maxEmbeddedClobSize=-1)"/>
