I don't think you're going to get much help writing Java code here; if
you want to discuss the pgsql-jdbc code, you should use that mailing
list rather than this one.  This mailing list would be the right place
for discussions about the wire protocol itself, though, so maybe
someone could give you some advice on that if you were more specific
about what problem you're having.  From the provided information it's
hard to be sure what's going wrong.
