Hi,

I am attempting to generate a simple Parent -> (n) Child relationship
usng hbm2java (used in Ant) from the hbm.xml files. I get
"Association references unmapped class" error but the
java class is in fact generated.

Hibernate version:
hibernate 3.0
tools 3.0 alhpa 1

Name and version of the database you are using:
PostgreSQL 7.4

The generated SQL (show_sql=true):
None.

Debug level Hibernate log excerpt:
Please see "Full stack trace of any exception" above.

Question: how can I correct this?

TIA,
Hugo Ferreira.

use search in this forum and you will see a lot of postings about this.....

basicaly the ant based hbm2java in the latest hibernate 3 tools is deprecated. we will have the new hbm2java in the next release.

Max,

Thanks for the reply.

I was looking into Hibernate 3 due to its "where" class tag and custom
SQL statements for insert/delete/update. I take it then that I have only
2 options:

1. Generate the classes manually
2. Use the eclipse tools

Is this correct?

Thanks once again.
Hugo Ferreira.

at the moment yes. you could also try to check out hibernateext from cvs and use the new ant tasks in there.

I will first try to checkout hibernateext and see what additional support it has
and report on that.

Thanks,
Hugo Ferreira.

look at http://opensource.atlassian.com/project ... se/HBX-112 for how to use it.

Feedback:

Downloaded CVS versions of Hibernate 3.0 and Hibernate extentions.
These were compiled and used for the experiment. These versions
seem to solve the 2 problems I had (class not found and the getter/setters
for the ide were not gernerated, please see http://forum.hibernate.org/viewtopic.php?t=939880 on latter problem).

Below I have the log. Just added this in case anyone is interested.
Please note the warnings related to velocity. I don't know if tis is related to
the condfiguration files or not (I cannot seem to add the pointer to the
configuration file in the new XML format). Will post this question in the relevant
linle (http://opensource.atlassian.com/project ... se/HBX-112).

Regards,
Hugo Ferreira.

the velocity is just that project not understanding when to moderate their log output - can be safely ignored. will try and make it shutup!

Hi there,

i recently ran into the same problem describe in this thread. I am just trying to migrate to hibernate3. Can someone tell me when the fixed version of the hbm2java stuff will be released, since i can't access CVS thorugh our firewall :-(

bummer firewall ,)

i expect to have a release out soon (i hope within two weeks)

-max

Hi Max,

thanks for your answer. I guess I'll have to delay my migration then... ;)

Kind regards
