I am creating a principal node in neo4j and creating its relationship with School, it works and principal object and relationship succesfully created in neo4j.
SchoolHasPrincipal school_has_principle = new SchoolHasPrincipal(school, principal);
principal.setHasPrincipalRelationship(school_has_principle);
Principal newPrincipal = principalDao.create(principal);
System.out.println("principal created>>"+newPrincipal.getId());
SchoolHasPrincipal shp = schoolHasPrincipalDao.create(school_has_principle);
System.out.println("relationship created>>"+shp.getId());
but after working for sometimes ,suddenly it gives error
