Hi,
I implemented a dynamic model as the following CUSTOMER(1)--(N)ACCOUNTS. I wrote the XML mapping as the following:
<hibernate-mapping>
<class entity-name="Customer" table="customer">
<id name="cId" column="c_id" type="long">
<generator class="native"/>
</id>
<property name="cName" column="c_name" type="string"/>
<set name="accounts" inverse="true" table="account">
<key column="c_id" not-null="true"/>
<one-to-many entity-name="Account"/>
</set>
</class>
<class entity-name="Account" table="account">
<id name="aId" column="a_id" type="long">
<generator class="native"/>
</id>
<property name="aName" column="a_name" type="string"/>
<many-to-one name="cId" column="c_id" entity-name="Customer" foreign-key="cId"/>
</class>
</hibernate-mapping>
Note that I only know the database schema at runtime so I can't have any compiled entity classes. My problem is that this works OK with mappings from N to 1, but doesn't work with mappings from 1 to N, i.e. collections. I tried googling about this but I can't find any example of such mapping using entity-names. The error that I am having is the following:
SEVERE: illegal access to loading collection
org.hibernate.LazyInitializationException: illegal access to loading collection
at org.hibernate.collection.AbstractPersistentCollection.initialize(AbstractPersistentCollection.java:341)
The queries that are being generated are the following:
Hibernate: select customer0_.c_id as c1_5_, customer0_.c_name as c2_5_ from customer customer0_
Hibernate: select accounts0_.c_id as c3_1_, accounts0_.a_id as a1_1_, accounts0_.a_id as a1_6_0_, accounts0_.a_name as a2_6_0_, accounts0_.c_id as c3_6_0_ from account accounts0_ where accounts0_.c_id=?
Does anyone have any clue about what is going on? A working example of what I am trying to do would be great too.
Thanks in advance,
Rui Vilão
