Ignoring fields in JPA with xml mappings

You've got a xml file that you need to persist to the database and you don't really want to use low level parsing and jdbc.

• Use trang to create a xml schema for the xml files
• Use xjc to create the java objects
• Use jpa with xml mapping to persist so there's no need to touch the generated source form xjc.  For fields you don't care about map them as transient.. e.g.

     <entity class="com.domain.xml_1_0.Site" access="FIELD">

              <attributes>

                   <transient name="siteInternalId"/>

                   <transient name="siteLinkage"/>

                   <id name="siteId"/>

              </attributes>

       </entity>
