Pefore putting it into CVS, you may want to post the stuff zipped up
somewhere so we can review your class design before committing it for CVS.
I also have a design that I have been playing around with that includes some
JNI stuff. I should be ready to post mine by monday. At this point, we
need to gather ideas about the best way to implement the Jdbc -> Valve ->
(Jni or 3050) Interfaces.

Hi,

I like it,

I have the classes implementing the jdbc interfaces almost done and
compiling ( everything is a no-op). I have to think about class
inheritance /interface inheritance a bit, and incorporate the JCA classes.

I have used the naming convention like this:

java.sql.Array interface >> org.firebirdsql.jdbc.FBArray


Is this OK with everyone? If no complaints, and I get the classes done, I
will commit them tomorrow or saturday.

I'm also setting up a build/ lib/ etc build directory structure with an ant
build script, and the jars for the interfaces and ant and junit in
appropriate places. That way if you have jdk you can download everything
you need at once.

I have no experience with jni, would it be faster to concentrate everyone
on the java-gds? Do we even have someone who wants to work on the jni?

I plan to work on implementing the JDBC stuff, especially the XA/JCA since
so far I seem to be the main person wanting it.

Thanks
David Jencks
