I have an error killing me while trying to set up the Many-To-Many relationships. I tried to simulate the Author-Work example from Hiberante examples but ended up with the following error. Can anybody please let me know what's going on. The error is thrown when trying to initialize the .hbm files at the set tag. Somebody please !
Brief Mappings ----
Code:
<class name="tests.Item" schema="test" table="Item" dynamic-update="false">
....
....
<set name="items" table="LINE_ITEMS" inverse="false" lazy="false" cascade="all" sort="unsorted">
<key column="item_id" />
<many-to-many class="tests.Lookup" outer-join="auto" column="lookup_id" />
</set>
</class>
<class name="tests.Lookup" schema="test" table="Lookup" dynamic-update="false">
....
....
<set name="lookups" table="LINE_ITEMS" lazy="false" inverse="false" cascade="all" sort="unsorted">
<key column="lookup_id" />
<many-to-many class="tests.Item" column="item_id" outer-join="auto"/>
</set>
</class>
Classes and Items dbase script -----------
Code:
class Item{
private java.util.Set lookups;
}
class Lookup{
private java.util.Set items;
}
CREATE TABLE LINE_ITEMS (
Item_Id INTEGER NOT NULL,
Lookup_Id INTEGER NOT NULL
);
The big huge error that is thrown. Please look for the sentence is CAPS. Guess that is where the error is.
