Re: Unusual object relation mapping possible with OJB ?

Hi Thomas, Sure, I need the link table. I read throught the examples in the link you gave before posting, my problem is that I do not have and don't want to make the relationship explicit on the object level. I.e. Persons or Address do NOT have a collection pointing to the other type. The

Thanks. Will this check all the addresses inside emails? Or just the first? Or... And what if emails is null? Thanks again, Gary --- [EMAIL PROTECTED] wrote: -Original Message- From: Gary [mailto:[EMAIL PROTECTED] I have a Person object that contains a list of 0-n Email

RE: Simple (I Hope) Howto Question

Hi Gary, This will execute a joined query similar to: SELECT A0.* FROM Person A0 INNER JOIN Email A1 ON A0.EmailID = A1.EmailID WHERE A0.name = X AND A1.address = Y So, yes, it will check all addresses inside emails. And if emails is null, it will return an empty collection. Hope this

RE: Multiple reads within the same transaction

Use ObjectCachePerBrokerImpl as your cache. It'll act as effectively a cache within the single transaction but won't share objects across transactions. -Original Message- From: Luis Cruz [mailto:[EMAIL PROTECTED] Sent: Monday, December 15, 2003 4:22 PM To: OJB Users List Subject:

Re: Making all implementors of IF persistent

Mhh, I guess you should add a class-descriptor for each Decorator class into the reository. then you have to define a class-descriptor for the IF and add extent class definitions for all decorator classes. Thomas [EMAIL PROTECTED] wrote: Hi, I want to map a table to an interface. I have some

Re: BATCH-MODE problem (repost)

Hi Stéphane, sorry for the delay. Unfortunately, the stack trace doesn't show line numbers for OJB classes. Probably this is because the jar for the release is build without debug info. Also I would like to know which version do you use. That would be great if you get RC5 sources, build target
