I am using hibernate 3.2.6, and spring 2.5.6
The database Im connecting to is: DB2 for Z OS 390 V8.1

When I run my testcase (below) I save the test file object. Hibernate DOES Save the object to the database, but my test blows out after the save, where it's trying to update the object with the correct id. I think that it's not getting the correct id (it looks like it's getting a '0' for the id), or Im not even sure why its trying to update the object that is already persisted. I dont know if this is a spring, hibernate, mapping, dialect, or etc issue.

My config:

The business object:

Code:

<hibernate-mapping>

   <class name="cat.edis.tmiweb.business.File" table="FILE">

      <id name="id" type="java.lang.Long" column="gen_file_id">
         <generator class="native"></generator>
      </id>

      <property name="creationTimeStamp" type="java.util.Date" column="crte_ts" />
      <property name="name" type="java.lang.String" column="file_nm" />
      <property name="type" type="java.lang.String" column="file_typ_desc" />
      <property name="description" type="java.lang.String" column="file_desc" />
      <property name="length" type="java.lang.Long" column="file_lgth" />
      <property name="contentBlob" type="blob" column="file_cntnt" />

   </class>

</hibernate-mapping>

FileDAO:

Code:

/*
 * Created on Oct 9, 2009
 */
package cat.edis.tmiweb.dao;

import org.springframework.orm.hibernate3.support.HibernateDaoSupport;

import cat.edis.tmiweb.business.File;

/**
 * @author dudekta
 *  
 */
public class FileDAOImpl extends HibernateDaoSupport implements FileDAO {

    /**
     * 
     * @param id
     * @return
     */
    public File load(Long id) {
        return (File) getHibernateTemplate().get(File.class, id);
    }

    /**
     * 
     * @param file
     * @return
     */
    public void save(File file) {
        getHibernateTemplate().save(file);
    }

}

My Test:

Code:

 public void testSaveBlob() {
        FileDAO fileDAO = (FileDAO)SpringTestInitializer.getContext().getBean("fileDAO");
        File file = new File();
        file.setName("TestMe");
        file.setType("txt");
        file.setCreationTimeStamp(new Date());
        file.setDescription("idc");
        
        byte[] testBytes = new byte[1024];
        byte byteValue = 1;
        for (int i = 0; i < testBytes.length; i++) {
            testBytes[i] = byteValue;
        }
        file.setLength(new Long(testBytes.length));
        file.setContent(testBytes);
        fileDAO.save(file);
        
        File dbFile = fileDAO.load(file.getId());
        assertNotNull(file);
    }

Output to console from Hibernate:

Also, Im connecting via type 2 driver. Not sure if this is an issue.

Code:

 
   /**
     * driver Type 2
     *
     */
    private static void setupdb2OS390GenDataPool() {
        Properties props = new Properties();
        props
                .put("pool",
                        "cat.cis.tuf.server.connector.jdbc.DriverManagerPool");
        props.put("url", "jdbc:db2:Z1U2");
