Hi Stephan,
In mapping an inheritance hierachy is not different for OJB/JDO. So if
you mapping is correct everything should work fine.
I've some questions regarding your classes and mapping:

Hi!
Yes; removeFromCache will remove the weak reference to the object and
make it eligble for garbage collection.

Hi,
Is it possibel to query a field from a different class, only having the
Where-criteria?
e.g.
Article.class and ArticleGroup.class are not mapped by OJB. Only a
ref-id exist. (Ariticle holds a field 'refArticleGroupID').
Now I want to query the class Article and some of the
fields from
Hi joerg,
OJB executes all queries on the database, so there must exist a mapping
of attributes to database columns if you want to be able to query them.
ReportQueries also use the repository.xml mapping to translate
attributes of classes to database columns.
Can you explain further what you are
Hi
have some one experience with ojb in a Clustered J2EE Environment
(Websphere)?
Did OJB work proper with more than 2 clustered servers?
If yes which was the settings of OJB (used Sequensmanager, used
connectionmanager
, settings in OJB.properties)
Thanks for your answer

With the imminent release of OJB rc5 (hopefully final and will be
branded as the real release!) I have started a discussion of OJB 1.1

The -dev list has come up with some plans, and I wanted to open
discussion to the -users as well ;-)
There is a starting point on the ApacheWiki at

hi peter,
imo this is on the to-do-list. as a workaround you can still use extents
and super-references but you should take care that the primary key is
UNIQUE within the class hierarchy.
for further details hava look at the thread: Extents and the various
inheritance hierarchy mappings in
This is my first ever post to a newsgroup, so I hope I get it right.
I've got the basics of OJB down, but now I am attempting to do some fairly
nested joins and OJB is not producting the SQL
statements I know I need (i.e. I've written them manually before).
This is about what I need:
SELECT
Hi Michael,
This is your SQL (minus all the parenthesis)

IMENU.LAST_UPDATED_BY, IMENU.NAME, IMENU.DISABLED

Hello,
I´d like to provide OJB with my own class to load/store objects in the
database. This is because I can´t get OJB to load this kind of beans, as
they consist of multiple rows in the same table.
To be able to load other classes with OJB, which reference these
objects, I would like to tell
Not at the moment. I figured since it wasn't taken before it would wait until
after 1.0. I have frozen my version of OJB because we're rolling the product
out next week. Sometime after that I was hoping to update OJB again and make
sure the patch still fits in and works well (if I have
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.

I don't know if you can use the database name that way in db.open(). Try
to use the jcd-alias attribute value of the jdbc-connection-descriptor
element. This one should either be in repository_database.xml, or even
repository.xml, if you've merged the two files in one. It looks like
you've not

Hi Armin,
Does DList automatically persist itself in the database on creation?
If you use DListImpl within a tx and you commit tx, then I think the
list will be persist itself. DListImpl_2 does not lock(persist) itself
while a tx is running. You have explicitly lock DListImpl_2 instances
