Do you register the driver as an extension? If so the lib are not=20
located in basis-link/program they are located in your user folder=20
3/user/uno_package/cache/uno_package/...
That would also explain why you can't set any breakpoint.
Another reason could be that your driver doesn't support=20
"com.sun.star.sdbc.Driver" or the driver was not registered.

If that doesn't work I could look at the code if you want to.

Best regards,

Ocke
