So, apart from one glitch I think that the other points are matters of
clearer documentation.
It is not clear from the Getting Started doc just what one has to do and in
what order. There are also inconsistencies betwen the default
build.properties and *.profiles as towhich variables are required. Some
tidying up is what it comes down to.
I am just left with my ODMG problem.
BTW for those who are a bit irritated by my not snipping out the older, and
now irrelvant, parts of this message stream, I am working with Lotus Notes,
and if I try to edit the message it just deletes the whole lot.

repository.xml wasn't copied in rc5, was a problem, has been fixed in
rc6. If you want to patch manually, change the ant copy in build.xml to
copy respositor*.xml instead of repository_*.xml =)
DB profiles are not copied on purpose, you need to copy the relevant
settings into build.properties yourself. The build.properties contains
all of the variables -- including jcdAlias and jdbcRuntimeDriver (in
build.properties they are "default" and "org.hsqldb.jdbcDriver"
respectively). You can C&P the properties out of profiles if you want
to. I deemed that copying all the profiles over was overkill as
ojb-blank is supposed to try to be minimal to help people get started.
The setting of the variables in repositor*.xml is done via ant property
substitution from the values in build.properties.
