No... Just the ldbc driver is compiled under 1.4. I just read the ldbc 
howto again and I missed something... It can be compiled under JDK1.3. I 
better redo the jar under 1.3. Should I upload a set of docs for ldbc?

Ldbc does support Oracle... I don't however. Its scary.
From the ldbc howto... The Oracle JDBC driver needs to be in the build 
class path. I don't have a recent Oracle jdbc driver. Oracle users need 
to roll there own. Or somebody in the team download and build ldbc.

Yes... I am sure Michele could look at the diffs and figure something 
out... But. Its just I hate getting him to make changes to support 
Ldbc/MySQL or whatever. I can put watches on the relevant files and do 
the diffs.

From the ldbc howto... Most likely JDK 1.2 also works.

I have no problems if it goes no further at present. It is just a go at 
abstraction. I will continue to work with it to see if I can improve and 
develop it. It is most certainly less strain on me if the development 
code is in the repository and it opens up the chance for others to look 
at it and test on there platforms if they are brave enough.
