Hi,
I have the following problem:
I have a table keywords which has two non-decomposed m:n mappings to the tables
document and file. The latter two both implement the interface SupportItem. In
my Keyword class i would like to have a collection of all SupportItems for this
keyword.
Is it

Hi,
Did you see my response to your other post? Please reply to the list.
No I didn't, sorry! I somehow gave up on this post...
Idea #2:
How about:
class-descriptor class=SupportItemI
extent-class class-ref=Document/
extent-class class-ref=Download/

Well, I would call it t_pal_model_supportitemI, and its a replacement
for t_pal_model_document AND t_pal_model_download
I guess that's what I wanted to say :-)
Tell us how you get on.
To remove any potential for misunderstanding (and since I'm a visual person :-))

As you can see on the picture i adopted your t_ prefix for tables :-) It makes
the repository.xml a lot easier to read! I hope you don't have a copyright on it ;-)
I will let you know how I get along. Thanks again!

Hmmm... now I'm confused again. :) Ah, you snuck in some other changes -
keyword now relates to pal_model? Or maybe not...
*** Assuming you want keyword and pal_model separate ***
The scenario is this: a PalModel should have a collection of SupportItemsI and a
Keyword
... and now for something completely different:
do i even have define foreign key constraints in my database??? I'm having the
impression that OJB is handling all the joins. Is it enough to have some loose
tables in my DB ???

Thank you very much for your time and effort Robert!
I'm trying to get your solution to work now (keep your fingers crossed! :-) )
Since this is all for my thesis paper you will get an honorable mention in the
acknowledgment section :-)
Thanks again and I'll let you know If it works!

Is it possible for you to post the snip of code that does the query? My

Hi,
Please see the attached image of my data model for reference (I'm sorry for the
attachment but it's kind of complicated to describe the scenario otherwise. A
picture says more than a thousand words :-) ).
How do I map the relationship between pal_model - download and pal_model - document?
ooops, I guess attachments are not allowed in this mailing list.
here's a link to the picture:

the same problem of course also exists for the keyword table.
Thank you, Patrick
Hello OJB Group,
I wrote a test case to check if my OJB configuration works properly but
everytime I run it I get the following exception:
org.apache.ojb.broker.metadata.ClassNotPersistenceCapableException:
java.util.Vector not found in OJB Repository
Here's the repository_user.xml
Hello everybody,
I just got started with OJB and i'm experiencing some problems. Here's the
scenario that i'm trying to get to work:
A DOCUMENT belongs to 1..n CATEGORY.
A DOCUMENT is relevant to 0..n PRODUCT_MODELs.
A DOCUMENT is written by 1..1 AUTHOR.
D DOCUMENT is described by 1..n KEYWORDs.

your repository_xml says: indirection-table=document_keyword.
typo? (missing 's');
This is not a typo. The table is called document_keyword.
handle join tables needed by many-to-many in OJB?
see .../db-ojb/src/test/org/apache/ojb/repository_junit.xml
usage
Fixed it. Changed nothing though. Still the same problem
