  1. JPA XMLColumn mapping • JAXB dependency • XML Schema xsd to JAXB XML bindings • @XmlRootElement • Required Annotations • @Persistent • @Strategy("org.apache.openjpa.jdbc.meta.strats.XMLValueHandler") • CRUD

  2. Query • Simple comparisons • Navigate single value path • Examples: • "Select o from ProductOrders o where o.podetails.customer.name = ?1" • Select o from ProductOrders o where o.podetails.customer.type = ?1

  3. Sample query test can be found under openjpa openjpa-persistence-jdbc/src/test/ java/org/apache/openjpa/persistence/xmlmapping.query/ TestXMLCustomerOrder.java Generated SQL for differenct platforms: TestXMLCustomerOrder.db2 TestXMLCustomerOrder.oracle TestXMLCustomerOrder.sqlserver

  4. Future Functionality • Namespace declarations • Other predicates • Scalar functions • Multi-valued
