Hi! The persistence should occur automatically when auto-update=true, even using Vectors.
Are you working with OJB Api, ODBC or JDO? The samples I've shown uses OJB Api. And of course, I use transactions... (or I store A and all instances of B, or don't store anything. This is a must when working with large apps). Maybe someone else can point you with more information... All that I can tell you is that this work. When I started with OJB I've used the samples, and they work. Maybe you have missing something in configuration. About the RemovalAwareCollection, you should use only if you need the instances of B being removed when you store A... Nothing about auto-update inserting objects.

I use a simple vector. When i do the stuff you are describing below, my new B object is not being created in the database, EVEN with my auto-update set to true. If i change anything on the A object, the change is recognized and saved. However, if i add or remove any objects from the collection of B objects, it is as through the change is not recognized. Should i start using the RemovalAwareCollection in order to make sure that any additions or deletions to the vector ? Note: the difference between what i showed below and the examples that come with OJB is that OJB examples always show the changes being made in the context of a broker transaction. I am not sure if this matters, but the way i am writing my interface to the persistence broker, i would like to be able to read objects out of the database, update them at will outside of broker transaction contexts, then bring the same references back and save the altered objects back to the database. any help you can provide would be helpful James Nyika Cambridge Technology Partners The global eServices company of Novell, Inc. http://www.novell.com >>> [EMAIL PROTECTED] 7/9/2003 6:31:08 AM >>> Yes, exactly what I do. But see, to B instances be stored in database, you must put auto-update='true' in your collection descriptor. In real, I use a collection class RemovalAwareCollection (or a specialized RemovalAwareList that I've created) to auto-delete. So, if I a.getCol().remove( 0 ); broker.store(a); the item in 0 is deleted from database, as expected. This is a must for my app. Best regards, Edson Richter ----- Original Message ----- From: "James Nyika" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 08, 2003 4:46 PM Subject: Re: 1:m-relation 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.
