Agreed, but we never said that we will support complete FB API or
even try to support it. This is simply not possible using available
Java standards (JDBC, JCA, etc.). We are writing JDBC/JCA-compatible
JDBC driver, and not IBX.Java or whatever you can call it.

I do not say that this is not possible. One can extend JDBC driver
functionality by subclassing currently available classes and
providing needed functions there. We have GDS_Impl.java that is
similar to gds32.h, so you are pretty free to write new component set.

I will answer your russian-language part of message privately because
I believe that here only English should be used (no matter how good
or bad it is, most of us are not native speakers).
