Hibernate version: 3.3.1.GA

Name and version of the database you are using: MySQL 5.0.67-community-nt (with driver mysql-connector-java-5.1.7-bin.jar)

I need to use what is called a "typed one-to-one association". Here are my classes (omitted packages/imports/getters/setters):

Code:

public class Proposal implements Serializable {
    private Long proposalId;
    private Contract contract;
    // ... getters/setters ...
}

Code:

public class Contract implements Serializable {
    private String name;
    private Address legalSitusAddress;
    private Address shipmentAddress;
    private Address mailAddress;
    // ... getters/setters ...
}

Code:

public class Address implements Serializable {
    private Long proposalId;
    private String addressType;
    private String street;
    private String number;
    // ... getters/setters ...
}

Note, Contract is a "component" (value type).

There is an example of "typed one-to-one association" in the Hibernate reference here: http://www.hibernate.org/hib_docs/v3/reference/en-US/html/misc.html#example-mappings-typed-onetone

It seems quite easy to understand and so, watching the example, I have created the following mappings:

Code:

<hibernate-mapping package="hibtester.model">
  <class name="Proposal" table="PROPOSALS">
    <id name="proposalId" column="PROPOSAL_ID">
      <generator class="native"/>
    </id>

    <component name="contract" class="Contract">
      <property name="name" column="NAME" length="50" not-null="false"/>

      <one-to-one name="legalSitusAddress" cascade="all">
        <formula>proposalId</formula>
        <formula>'LE'</formula>
      </one-to-one>

      <one-to-one name="shipmentAddress" cascade="all">
        <formula>proposalId</formula>
        <formula>'SH'</formula>
      </one-to-one>

      <one-to-one name="mailAddress" cascade="all">
        <formula>proposalId</formula>
        <formula>'MA'</formula>
      </one-to-one>
    </component>
  </class>
</hibernate-mapping>

Code:

<hibernate-mapping package="hibtester.model">
  <class name="Address" table="ADDRESSES">
    <composite-id>
      <key-many-to-one name="proposalId" column="PROPOSAL_ID"/>
      <key-property name="addressType" column="ADDRESS_TYPE" length="2"/>
    </composite-id>

    <property name="street" column="STREET" length="50" not-null="false"/>
    <property name="number" column="NUMBER" length="4" not-null="false"/>
  </class>
</hibernate-mapping>

There are some differences from the example: I have 3 addresses and they are in a component. But I think it's not this the problem.

Trying to create the schema using schema export Ant task I get:

Code:

schema:

BUILD FAILED
C:\...........\build.xml:76: Schema text failed: An association from the table ADDRESSES refers to an unmapped class: java.lang.Long

It's not clear to me the problem and how to resolve it. I have used Long type for ids and normal fields in other projects without problems.

Log at trace level using log4j seems not to help:

Code:
