> Actually there are 3 places where this error is generated: org.apache.ode.dao.jpa.MessageExchangeDAOImpl.getEPR, PartnerLinkDAOImpl.getPartnerEPR and possibly (not tested) PartnerLinkDAOImpl.getMyEPR(). The cause is: variable which holds xml representation of EPR is not null, but empty string (""). It seems that OpenJPA in conjunction with Oracle uses empty string when restoring these values from database.
