Aslak, I got your email, but before that I had sent the one below - I got past the
metadata
problem.
I tried to use the pkgen feature with the vendorseq option, but it gave errors stating
the pktable
had to be specified. I thought this would not be required if using the database's
automatic
sequence generation (SQL Server IDENTITY). Also it did not generate the create
methods in which
the primary key column is absent. I noticed it is putting in a "todo" comment that
this needs to
be done. Am I too early, is it not implemented yet ?
I'm also getting an error on weblogic ejbc - something about Local and LocalHome
interfaces being
exposed in remote interface methods (as arguments to create it looks like). But I'll
work on that
a bit more - it may be because I've specified view="both" and also checked the
local/remote
checkboxes in the gui.
One question - I haven't understood why we need the xxCMP objects - why not just use
the Entity
Bean ?
