hbm2ddl - Could not determine type for custom UserType

cbredesen · **Posted:** Fri Sep 09, 2005 10:43 am

Hi All,

The fact that this isn't listed in the forum anywhere leads me to believe I'm probably missing something silly. Since using H3 (it seems), I have not been able to generate DDL from my mapping files. In particular, it has trouble with my user types. I tried both the "legacy" schema export task, and the 3.1.alpha5 hibernatetool. Both report the same error. These mapping files work perfectly in my application, and the hibernate.cfg.xml file works in the Hibernate Console.

Any ideas?

Hibernate version:
3.0.5

Mapping documents:

Code:

<hibernate-mapping>
   <class name="com.comerxia.core.model.Component" table="COMPONENT">

      <id name="id" column="ID" type="java.lang.Long">
         <generator class="sequence">
            <param name="sequence">COMPONENT_SEQ</param>
         </generator>
      </id>

      <property name="content" type="java.lang.String" update="true"
         insert="true" column="CONTENT" length="50" />

      <property name="activeIngredient" type="java.lang.Boolean"
         update="true" insert="true" column="ACTIVEINGREDIENTFLAG" />

      <property name="units"
         type="com.comerxia.core.dao.hibernate.type.ComponentUnitsEnumUserType"
         update="true" insert="true" column="UNITS" />

      <property name="amountPerServing" type="java.lang.Double"
         update="true" insert="true" column="AMOUNTPERSERVING" />

      <property name="dateCreated" type="java.util.Date"
         update="false" insert="false" column="DATECREATED" />
   </class>
</hibernate-mapping>

to determine the type of the usertype the usertype class must be in your classpath...

I had referenced them but I did it incorrectly. I needed to use a pathelement rather than a fileset to point to .class files.

Thanks, Max.
