Edson, Can i ask you to give an example of how you add more B objects the the collection you described below do you do something like this :
//get broker broker = brokerfactory.defaultInstance(); //fetch an A object that has say 3 B objects in the collection. ... //create a new B object B newB = new B(); //add to the collection A.getCol().add(newB); //persist the A broker.beginTransaction(); broker.store(A); broker.commitTransaction(); ? James Nyika Cambridge Technology Partners The global eServices company of Novell, Inc. http://www.novell.com >>> [EMAIL PROTECTED] 7/8/2003 12:24:28 PM >>> Hi! I'm largelly using 1:N and M:N relationships in my project. I'll try to give you a little tips: 1) Use your N parts as Collection. If you are using PersistentFieldPropertyImpl, then you should have public class A { private Collection myNpart; private Integer id; public void setId( Integer newId ) { id = newId; } public Integer getId( ) {return id;} public void setCol( Collection newCol ) { myNpart = newCol; } public Collection getCol( ) { return myNpart; } } public class B { private Integer id; private Integer idA; private A a; public void setId( Integer newId ) { id = newId; } public Integer getId( ) {return id;} public void setIdA( Integer newIdA ) { idA = newIdA; } public Integer getIdA( ) {return idA;} public void setA( A newA ) { a = newA; } public A getA( ) { return a; } } 2) Your .xml should be similar to: <class-descriptor class="A" table="TB_A"> <field-descriptor name="id" column="ID" jdbc-type="INTEGER" primarykey="true" /> <collection-descriptor name="col" element-class-ref="B"> <inverse-foreignkey field-ref="idA"/> </collection-descriptor> </class-descriptor> <class-descriptor class="B" table="TB_B"> <field-descriptor name="id" column="ID" jdbc-type="INTEGER" primarykey="true" /> <field-descriptor name="idA" column="ID_A" jdbc-type="INTEGER" primarykey="true" /> <reference-descriptor name="a" class-ref="A"> <foreignkey field-ref="idA"/> </reference-descriptor> </class-descriptor> And this should work. You don't need to specify auto-retrieve, because by default it's true. Auto-update and auto-delete are false by default. Some people like to work with specialized collection classes. In particular, I work always with RemovalAwareList (a collection that know how to persists deletes in the collection). To archieve this, your should be more specific in collection descriptor like this: <collection-descriptor name="col" collection-class="org.apache.ojb.broker.util.collections.RemovalAwareList" element-class-ref="B"> <inverse-foreignkey field-ref="idA"/> </collection-descriptor> Of course, you could mixes the several other options that OJB offers to you, like auto-increment, proxies and so on. In this case, I'll recomendly you to use cvs HEAD that has several fixes for these options over rc3.
