Uncle. It seems that JBOSS is designed assuming that it has full control
of creating tables. Well in my case I already have a database allready
set up so my view of things is how do I stuff this database into JBOSS.
I don't think it is worth the discussion which approach is right or
wrong
Uncle. It seems that JBOSS is designed assuming that it has

This isn't really true. JBossCMP makes the assumption that if the table
structure is not specified the Application Deployer does not care what the
structure is, as long as it runs.

Ok, you are not getting it.
I am it's just that the moon is gone ;)
Although JBossCMP does not generate the column names you would like, the
system still runs. Is that correct? (i.e., this is still a suggestion)
If I use the jbosscmp-jdbc.xml file I can get it to work.
Ok now that
Hi guys,
I've just been skimming this thread, but it strikes me as possible
that it is based on a misunderstanding. Dave, do you know that
you should not define a cmp field for a foreign key column? So
changing the naming convention wouldn't be necessary to get it to
work by default. Sorry
Don't be sorry, be happy ;)
the problem is that the name specified in the cmr-field-name is not the
database column. Jboss assumes that the database column name is the
cmr_field_name (left side) +_ + cmr_field_name right side. What I
think makes more sense is for the cmr_field_name by default

Do you have to use the jbosscmp-jdbc.xml file? If you don't, what happens?
Does the system generate two columns with the same name?
The database table already exsists. Basically I have to use
foreign-key-fields and set

About time :)
Yup this is a suggestion. I agree 100% we need to avoid using
jbosscmp-jdbc.xml.
Ultimately at the database level for each table there has to
be a unique
column name(s) that acts as a foreign key for the

You can set a different column name using @jboss:column-name (see
