Re: Borrow broker from pool failed. in production server
If you are leaking brokers, that doesn't solve the problem - it just works around it. We had the same problem with our Spring/JTA/OJB application and I discovered the problem was due to using Spring DAOs directly instead of going through the Spring transaction layer.

TxCheck, JTA and Spring
We are using Spring and JTA in container to manage transactional DAOs. We have TxCheck enabled and when one of our transactional DAOs is called in JBoss, we get a "No running tx found..." message. Should we disable the TxCheck since we are not using PB transactions or does TxCheck handle this case and we just have something misconfigured? - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Problem with Anonymous keys in 1.0.4
I'm having trouble getting a simple anonymous key example working in
my tests. My class descriptor is something like this:
My Java class looks roughly like this:
public class ChangeStatus extends BaseObject {
//private int statusId;
//private int changeSubmissionId;
private StatusMaster status;
private ChangeSubmission changeSubmission;
// setters and getters...
}
The Desk and Drawer example says to add access="anonymous" to the
field descriptor and it should start to work but I consistently get
this error:
* SQLException during execution of sql-statement:
* sql statement was 'INSERT INTO gov_change_status
(status_id,change_submission_id,date_created,date_modified) VALUES
(?,?,?,?) '
* Exception message is [Column 'STATUS_ID' cannot accept a NULL value.]
* Vendor error code [3]
* SQL state code [23502=NOT NULL VIOLATION]
* Target class is 'domain.ChangeStatus'
* PK of the target object is [id=0]
* Source object:

If I create and set the FK ID fields explicitly (the commented out
fields in the java code above), it works fine. What am I missing?

Fwd: OJB dependencies

OJB Dependency breakdown
Here's my first pass at determining how OJB 1.0.4 uses the various dependencies. Basically I just moved each package out of lib and ran compile/test to see what failed and how. Comments welcome.

Re: problem with between criteria
Carlos, that's odd. I just noticed that the Criteria APIs seem to have a
pattern where they allow either raw columns or the field name and the field
name was not working for me. Unfortunately I just moved this code over to
use a raw SQL query so I can't get you any error messages. Thanks for the
response anyhow.

problem with between criteria
I'm using
crit.addBetween("invoke_date", new Timestamp(startDate.getTime()),
new Timestamp(endDate.getTime()));
The problem is that that between does not have a Field API like
addFieldBetween so I need to use the raw column name. Is there any reason
why this API is missing?
