Hi,
I have a problem with the creation of composite primary keys with forgein keys. An exception is thrown when executing an ant-taks with maven and hbm2ddl. It mentions that the class of the composite id is not found, but I thought this class will be created by excuting hbm2ddl or hbm2java.
Maybe someone here got the same error and probably can help me.
Thanks in Advance!
The mapping file:
Code:
?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="testpackage" default-access="field">
<class name="testpackage.testclass" table="TESTTABLE_T" mutable="false">
<composite-id name="id" class="testclass$Id">
<key-property name="roleId" access="field" column="ROLE_ID"/>
<key-property name="permissionId" access="field" column="PERMISSION_ID"/>
</composite-id>
<property name="created" column="CREATED" type="timestamp" not-null="true"/>
<many-to-one name="role"
column="ROLE_ID"
not-null="true"

</class>
</hibernate-mapping>
