>From Jody's original email:
I'm creating the database on the fly and
locating it in c:\temp, so I don't need to have the actual database
files in the jar, just the .prp file.
This is definitely possible, but any change has its issues. For
instance, the relativeToProperties flag would have to be ignored; paths
specified in the prp file would have to be either absolute or would be
considered relative to the working directory.
This will be fixed in a future Lutris release of InstantDB, unless it's
open sourced first and a community member sends in a patch (I have no
control over when InstantDB becomes OSS, it's a Lutris management
