Spring Transactions
Hi there, I have an implementation of my model with OJB using just PersistenceBroker. Now I'm looking into adding transactional support, looked into ODMG but it seems complex to implement since all my mapping and query is in Broker lingo, so I'm looking at injecting Transaction support for my process methods with spring, that way I shouldn't need to change config files and just one class that interfaces with the Broker. Now, I tried to look for samples outthere found this http://www.springframework.org/node/116 But after setting it up transactions don't seem to be happening. So my questions are. 1- Do I need to use InnoDB on Mysql ? My tables are MyIsam. 2- Am I missing any other feature besides applicationContext setup and deriving my class from PersistenceBrokerDaoSupport? Here is the applicationContext.xml PROPAGATION_REQUIRED PROPAGATION_REQUIRED PROPAGATION_REQUIRED,readOnly Thanks Sam
DListImpl
Hi everyone, I've been using PB to implement my persistence framework, works wonders so far Now I came accross a point that needs to use a list in a class similar to DListImpl, where I can have a collection of objects without having to set a forignkey on the N side Is there a way of using DListImpl from PB? And if not Is there a way of initializing the DListImpl without having to do OJB.getInstance().newDListImpl()?? That way I can keep my convention of not using Persistence related code in my model.

M:n relation
Hi everyone, here is my problem with m:n non-decomposed associations
I have to classes Actor and Role,
the problem is that when I try to persist the m:n relation the
indirection-table doesn't get populated
I've looked in the Logs and something interesting was happening.
After inserting an actor or Role, OJB is issuing a DELETE !!!
here is my code and mapping info
Help appreciated

Sorted list
Hi everyone, I've been trying to find a way to have a sorted list where I can do a get method on the key, right now I'm using to lists, one that I have implemented based on the java SortedMap list and a vector, then when OJB uses the setList method I go and add all the elements to the sorted map, and viceversa Problem is of course performance I've been looking in implementing my Sorted List by implementing the ManageableCollection Interface, the question Is if that's all I would need to do? Just implement those methods and have my repository collection tag to my own ? Anyone has come across this before?

1:m relation not updating
Hi there, Here is the situation.. Say I have class A and class B 1->m I created the repository.xml Everything works fine when storing A to DB with a couple of B's Tx.lock(a, Transaction.WRITE); Tx.Commit Next step is to load a and add more B's and then save it again. I created the query. And all a and the related B's get loaded ok Now I add a couple more B's And store a Tx.lock(a, Transaction.WRITE); Also tried Tx.lock(a, Transaction.UPGRADE); But the new B's don't get inserted in DB. Any ideas Thanks Sam - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
RE: Problem retrieving class
Found the problem. After sleeping a couple of hours :-/ The issue was that I defined dynamic proxy in my repository.xml so it was retrieving a proxy instead of my own class. Now I have to do some more reading on proxies..

Problem retrieving class
Hi there, It's late and I've been trying to do this for a while so I'll just post this message hoping I get a reply in the morning I have a class structure, everything works fine when I store the objects in DB, but after doing a select and trying to cast the object to my type I get a classCastException i.e Account acc = (Account) result.get(0); Any ideas?
