The answer should be in the build.xml file in the samples.
<!--
If you want m:n relations, they must be specified like this.
Note that tables declare in multiple locations must all have
the same value of the generate attribute.-->
<!--many2many>
<tablea generate="true" name="persons"/>
<jointable name="reservations" generate="false"/>
<tableb generate="true" name="flights"/>
</many2many-->

Subject: [Middlegen-user] many-to-many relationship middlegen for
hibernate mapping files
Hi
Recently I started exploring hibernate and middlegen.
Here is simple test.
I used 3 tables say A,B and A_B (third table for
many-to-many relationship).
I found that for many-to-many relationship one
seperate class is ceated(A_B) and also for PK class
A_BPK is created.class A has one-to-many relationship
with class A_B and same is the case with class B.
What we want is that A should have Set of B as
attribute and B should have Set of A as attribute
rather than that of A_B, i.e. there should not be
third class A_B.
We are able to do this manualy by using many-to-many
relationship tag in mapping file but thru' middlegen
we are not able to achieve (middlegen gives us Set of
A_B as attribute in class A and B both and this leads
to the use of composite id and extra level of
indirection).
Any help,
thanx in advance.
Sanjeev
