My first question is: since there are many-to-many
relatioships between
DOCUMENT and CATEGORY and DOCUMENT and KEYWORDS there are two
join tables
called DOCUMENT_CATEGORY and DOCUMENTS_KEYWORD.
-Original Message-
your repository_xml says: indirection-table=document_keyword.
typo? (missing 's');
This is not a typo. The table is called document_keyword.

hi patrick,
the collection-descriptor is wrong :

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.
, pretty messed up, but I am a newbie. OJB is giving me:
SELECT DISTINCT
A0.DISABLED,A0.NAME,A0.SYSTEM_NUMBER,A0.LAST_UPDATED_BY,A0.LAST_UPDATED
FROM IMCOP.IMENU A0,ASSOC_IOBJECT_IMENU A1,IMCOP.IOBJECT
A2,ASSOC_IGROUP_IOBJECT A3,IMCOP.IGROUP A4,IMCOP.ASSOC_IGROUP_IUSER
A5
WHERE A4.SYSTEM_NUMBER=A5
Hi Michael,
This is your SQL (minus all the parenthesis)
SELECT DISTINCT IMENU.SYSTEM_NUMBER, IMENU.LAST_UPDATED,
IMENU.LAST_UPDATED_BY, IMENU.NAME, IMENU.DISABLED
FROM ASSOC_IGROUP_IUSER INNER A5 JOIN IGROUP A4
ON A4.SYSTEM_NUMBER=A5.GROUP_SYSNO
INNER JOIN ASSOC_IGROUP_IOBJECT
Great! You're right. I am linking incorrectly, but to fix it is another
story. Writing path expressions is still somewhat of an enigma. I even
have a diagram, but it's just going to take some work. Any ideas? Thanks a
bunch for the help.
