 Post subject: Hibernate3.1: How to use Custom Identifier?

Using: Hibernate3.1, Hibernate-tools3.1beta2, Oracle10g.

    Attempting to upgrade from Hibernate3.0 to Hibernate3.1. This all used to work before the upgrade.

    Having a problem starting up my application in JBOSS server (It's a JBOSS service). I get the folowing errors (the lines marked with ">>>>" are my own debug lines). Essentially it's having problems with a custom identifer in one of my mapping files. After debugging the Hibernate3.1 source, I found that the dialect "Oracle9Dialect" can't find the type for custom identifier (specifically, in file TypeNames.java at method get()).


The exceptions I get are:

Code:

Specifically, the lines in the above exceptions that may hint at some problem are:

...
Problem starting service MyCompany.com:service=LogHibernate
org.hibernate.HibernateException: org.hibernate.MappingException: No Dialect mapping for JDBC type: -2



The identifier definition in my mapping file:

Code:
       <id name="evtLogId" type="mycompany.util.common.type.GuidType">
         <generator class="mycompany.util.common.id.GuidIdentifierGenerator"/>
      </id>



The method in TypeNames.java that is having trouble finding the type for the identifier:


Code:
   public String get(int typecode) throws MappingException {
      String result = (String) defaults.get( new Integer(typecode) );
      if (result==null) throw new MappingException("No Dialect mapping for JDBC type: " + typecode);
      return result;
   }


Any help would be appreciated.

Thank You.

Are you trying to use BINARY type for sqlTypes() return in the GuidType?
Use VARBINARY instead.

or, post the GuidType code.

I didn't write the code, so I'm not exactly sure what you mean. However, below is the code for GUIDType.

Code:
public class GuidType implements UserType, Serializable {
   
   private static final long serialVersionUID = 1L;

   private static final int[]  SQL_TYPES = {OracleTypes.RAW  };
   
    public int[] sqlTypes()
    {
        return SQL_TYPES;
    }

    public Class returnedClass()
    {
        return Guid.class;
    }

   public boolean equals(Object x, Object y) throws HibernateException {
        if ( x == y ) return true;
        if ( x == null || y == null) return false;
       
        return x.equals(y);
   }

    public int hashCode(Object x) throws HibernateException
    {
        return x.hashCode();
    }

   public Object nullSafeGet(ResultSet rs, String[] names, Object owner) throws HibernateException, SQLException {
        byte[] b = rs.getBytes(names[0]);

      if (b == null)
         return null;
      
        return new Guid(b);
   }

   public void nullSafeSet(PreparedStatement stmt, Object value, int index) throws HibernateException, SQLException {
      if (value == null) {
         stmt.setNull(index, OracleTypes.RAW);
      }
      else {
            Guid guid = null;
            if (value instanceof String) {
                guid = new Guid((String)value);   
            } else {
             guid = (Guid)value;
            }
         stmt.setBytes(index,guid.toBytes());
      }
   }

    public Object deepCopy(Object value) throws HibernateException
    {
        return value;
    }

    public boolean isMutable()
    {
        return true;
    }

    public Serializable disassemble(Object value) throws HibernateException
    {
        return (Serializable) value;
    }

    public Object assemble(Serializable cached, Object owner) throws HibernateException
    {
        return cached;
    }

    public Object replace(Object original, Object target, Object owner) throws HibernateException
    {
        return original;
    }
}

replace
private static final int[] SQL_TYPES = {OracleTypes.RAW };
with
private static final int[] TYPES = new int[] { Types.VARBINARY };

Thanks! That solved that problem! Of course, now I'm onto my next set of exceptions with my upgrade to Hibernate 3.1. I'm getting problems with named queries.

If you have any knowledge about named query exceptions with the new HIbernate 3.1, I've posted it at http://forum.hibernate.org/viewtopic.php?t=951569

Thanks again for your help!
