How to handle constraint violations (ODMG)
Hi,
I have USER table which containts a column 'email' which should be unique.
When I try to write an object to the table using the ODMG api I can catch a
TransactionAbortedException. How can I get to the SQL error code?
I tried the following, which did not work:
try {
tx.commit();
} catch (TransactionAbortedException ex1) {
Throwable ex = ex1.getCause();
if (ex instanceof PersistenceBrokerSQLException) {
if (((PersistenceBrokerSQLException)ex).getSourceException() instanceof
SQLException) {
SQLException sex1 =
(SQLException)((PersistenceBrokerSQLException)ex).getSourceException();
logger.info("Exception sql state: " + sex1.getSQLState() + ", " +
sex1.getErrorCode() + ", " + sex1.toString());
}
The sql state is null and the error code is 0. (I am using ojb 1.0RC4 and
PostgreSQL 7.3).
Best regards,
Andreas

Re: PersistenceBrokerFactory exception
Hi Carlos, seems the broker-pool is exhausted. OJB version? Do you mix PB-api and ODMG-api in your code? I don't mean > PersistenceBroker broker = ((HasBroker) tx).getBroker(); that's ok. I mean direct use of PersistenceBrokerFactory to create PB instances? Normally the odmg-api close all used PB instances after use. Or, you have to many concurrent threads running on the server. But default pool size is 100. So I think it's not as simple as that ;-) regards, Armin Boyes, Carl wrote: Hi, Our OJB based application has just gone into system test and we are intermittently experiencing the below error when calling: PersistenceBroker broker = ((HasBroker) tx).getBroker(); Can anyone let me know what I am doing wrong?

Re: New xdoclet ojb module version
I have been in contact with Erik Hatcher on XDoclet (he is also an Apache member) and he says that there is about 0% chance of getting it into XDoclet 1.2, and he doesn't expect that there will be a 2.0. He was open to putting an OJB module into the XDoclet 2.0 distribution if we can get someone to make and maintain it, but was of the opinion that we will need to host the XDoclet 1.X plugin if it is going to be hosted. I am all for putting it in our CVS as the plugin works very well and, imho, is one of the best ways to do repository configuration. XDoclet is BSD licensed so having code dependent on it in our CVS is okay. -Brian On Monday, November 10, 2003, at 10:53 AM, Thomas Dudziak wrote: I've created a new version of the xdoclet ojb module which now also supports the object-cache tag, and the factory-class, proxy-prefetching-limit and otm-dependent attributes.

Re: OJB as JDO implementation: status request
Right now there are two JDO implementations in OJB. The one that works is dependent upon the JDO reference implementation so it not always an acceptable option. This one works by using OJB as a plugin back end to the reference implementation. It is full compatible but not fully convenient (right now it requires maintaining .jdo and the repository_user.xml both). The licensing issue is also a potential problem as you have to contact Sun and ask permission to use the JDORI for commercial production use. Everyone I know of who has asked has received permission. The second implementation is the OJB-native implementation. If your release target is anytime soon, don't use this yet. Many functions are still just stubs. Everything that we need to finish putting together the OJB-native JDO impl is in place -- locking down bugs and boosting performance for 1.0 has just been higher priority than filling in the stubs for JDO. -Brian On Monday, November 10, 2003, at 10:39 AM, Sergey V.

Re: dynamic proxies (simple question)
Hi, >>Perhaps you should look at using proxies on your collections first This would be a nice idea, but the problem is, that if i am right about what is taking time, it is the updating of a set of objects. When a page is submitted, each of about 30 objects are loaded, updated, stored, and the cache cleared. The problem here is that each of these objects is referencing two objects, which will each cause the loading of hundreds of other objects. If i can proxy these two references, i think it will almost completely solve the problem on it's own. I think i understand proxying now, (the interface requirement makes a LOT of sense once you know what you've got to do and try to think why!)

RE: dynamic proxies (simple question)
Hi Daniel, Perhaps you should look at using proxies on your collections first (this will require no refactoring, just add proxy="true" to your collection descriptors) and then possible proxy your references (requires interface) before looking at using dynamic proxies on all classes. This seems to be the concept that works well in many cases.

Error at run time by a beginner
Hi
I make my first try, so I arrive to compile and to run it, but it fail
somewhere.
I use the presistent broker, only.
and I use the same Product base than the tutorial one.
Does somebody understand where is my mistake ?

One more question: In the class employee i have private Job job; If i proxy this Job reference, should it become: private IJob job; // where IJob is an interface to Job class. So, if i understand correctly: The interface must have ALL prottypes in it. So to answer my last email, IJob should extens IBaseBO.

dynamic proxies (simple question)
I've been using OJB for a month or so and am pretty impressed with it! However, with the application getting complicated, updating a bunch of objects is taking a long time - i'm assuming this is because each time it is loading the whole tree of interconnected objects! So my solution would seem to be proxies. The tutorial on dynamic proxies isn't too clear. It says: "To use dynamic proxies the persistent class in question (in our case the Article class) must implement an interface (for example InterfaceArticle). This interface is needed to allow replacement of the proper Article object with a dynamic proxy implementing the same interface." My question is: what must this interface provide? Nearly all my BOs (all that i want to proxy) are subclasses the BaseBO bean (with two properties - deleted and id). Can i create an interface with just these two methods, or do i have to create an interface for each bean, with all methods in it? Thanks, Daniel.

Split table into many classes ???
Hello I 'm trying to split a table into many classes which are containing only a part of the datas . TABLE TT: NUMBER ID VARCHAR NAME VARCHAR DESCR BLOBDATA I want to have 2 classes one containing a small description ( ID , NAME and DESCR) and the other one Containing the data ( ID and BLOB ) It's easy to do it in the repository My problem is when I try to load all the ttdescription, the BROKER generate a request which is also containing the fields described in the ttData instead of limiting the select to the values of the column in ttdescription. Is it normal ? Do I have to manualy change the query for removing the not pertinent columns ? I'm using the cvs source of Ojb in the front of a Oracle 9i DB .

Re: Question about getIteratorByQuery
Thomas Thanks for you answer. Ok for a simple database call, but when we make this call to the persistence layer, which bring data step by step does it works ? I make a request on some table with 3 enreg numbers 1, 2 and 5 I ask some iterator at the prsistence layer. And make next. Somebody create a new enreg : the number for When I make next from the number 2. Will I get the number 4 or the number 5 ? Thanks for any help.

Would be fine if you check this closer. 1.01 fix many bugs from 1.0 And I am sure many people will welcome the changes.
