Hi,
I am new to OJB. I tried to look for docs on OJB at Jakarta but got nothing like a
tutorial. Could anyone point me the some good beginners reading material. Or if
possible kindly provide some sample source code?

Hello:
I can't find the OJB module for XDoclet.
Does it still exist? Where should I look?
Thanks,

Ok, well I figured out that the version of Xdoclet-ojb that comes compiled
with RC4 does not have this feature in it.
I downloaded the most recent jar from CVS, and now it works, sort of.
If it put my @ojb.field description in the class comment, it will now had
the field-description, but now it a
So, let's say I have a base class 'BusinessObject' with a property called
'guid'
So, I have two classes, both extend BusinessObject, named 'dog' and 'cat'.
My database (which already exist), has a field in the tbl_dog table called
"dog_guid", and the tbl_cat has "cat_guid".
Before using Xdoclet
Works for me. Thank you.

hi istvan,
this looks like a problem in your mapping. if ojb finds descriptors for
the fields it prefixes them with a table alias (a.name).
if no field is found the name from the criteria is used.

Hi,
I don't actually use DynamicProxies (I do use them elsewhere, just not in in
OJB), so I can't be much more help - but... The whole point of proxies is
that you *shouldn't* get to the real class. You should always talk to the
proxy, and the proxy talks to the real object. If you nead to expose

Hello,
I am wondering what is the best way to handle Criteria.addEqualTo() and
Criteria.addIn() when the field contains an object referenced from
another table. For example.
I want to be able to query A objects using something like
criteria.addEqualsTo("b", ).
Hi all,
do I have to reference all persistent (and mapped) objects by their
interface if
i want to use proxies?

Ok, I removed the hashCode too and OJB works well. But my hashCode was
based on my object's pk. Now I have some problems putting my objects in
a HashMap.
So what can I do now ? Is this a bug that will be corrected or is it a
known problem that will remain unchanged in the future ?

hi all,
when using dynamic proxies, do i allways have to use the the interface
to access the
objects? What do I have to change in the code to switch from
"real" classes to proxies?

I realized. The getBroker then getConnection is the way.
Thanks for tips from everyone.
