ImplicitLocking clarification / confusion

Hello, I'm using OJB 1.0.3 with the ODMG api and I'm confused about implicit locking. I prefer from past experience to have ImplicitLocking=false in my OJB.properties and this is what I've done for quite some time. I've started getting (sometimes) LockNotGrantedExceptions on objects that

Disabling Optimistic Locking at Runtime

Hello, I am using optimistic locking for a few classes/tables in my application. However, in certain circumstances when my application starts up, I want to disable optimistic locking for the lifetime of the application. I have tried to modify the repository metadata at runtime, but I

ObjectEnvelopeTable.reorder() problems

Hi All, I'm currently having a problem with reordering of written objects done by the org.apache.ojb.odmg.ObjectEnvelopeTable.reorder() method. I have implicit locking off, and I always lock objects in the order they would have to in order to maintain referrential integrity. That is, I

Re: ObjectEnvelopeTable.reorder() problems

every time I call lock(). Is this correct? Is flush() nothing more than a workaround? Colin Colin Kilburn wrote: Hi Armin, thanks for the response. I'm using OJB 1.0.1. I've never noticed the TransactionExt.flush() method. Calling it does seem to fix the problem. I do have 2 questions, however

Re: ObjectEnvelopeTable.reorder() problems

Thanks Armin. flush() fixes the problem. I just tried upgrading to 1.0.2, but that doesn't appear to fix the problem. I can live with the flush() workaround until that is solved. Thanks again, I appreciate your help. Colin Armin Waibel wrote: Colin Kilburn wrote: Hi Armin, thanks

[OT] Surrogate/Artificial Primary Keys and large databases

Hi All, I regularly use surrogate/artificial/auto-increment/meaningless primary keys for most of my tables. While I've only been a full-time developer for about 6 years, I have seen this as commonplace and certainly not unusual. I also find they map nicely to the concept of Identity in O/R

Automatically trim trailing spaces in MS Sql Server

Hi All, I can't find anything about this in the archives or by googling, but I can't be the first to want to do this... Data in a CHAR column is padded with spaces. This is fine for storage, but how can I tell sql server or OJB that I don't want the trailing spaces when I retrieve the column

Re: using OJB with Struts and Eclipse

Phillipe, I keep my repository*.xml files in WEB-INF/src, and eclipse seems to copy them over to WEB-INF/classes for me. I also use the Sysdeo Tomcat plugin, which may be what's actually helping me out. HTH, Colin [EMAIL PROTECTED] wrote: Hello, I am currently building a web application

where-clause criteria for collection-descriptor?

Hi All, I'm sorry if this question has been asked before, the archive search capability seems to be broken. This is my first project using OJB, and I enjoy the convenience of the collection-descriptor/inverse-foreignkey mapping. What I'd like to do however is specify additional criteria as
