#186 No Primary Key reported

[Anonymous]

steffen.kroh@triggersoft.com

I execute the run middlegen but it fails to find a the
primary key information for the table. This is a fair error
as the information is not available to us from this
database.
Is there a way to generate the classes without any
primary key information? (which i can manuallyy enter
later?)
Or if i have the sql statement, can the hbm structure be
generated from that?

I've tried to set the
fkcmp="false"
guid="false"
with in the <cmp20 tag. but then get the error:

eys where some of the columns are also foreign keys.
This is because all columns
of a primary key must be CMP fields. See EJB 2.0.

Otherwise if i set them both to true again i get this error:
