autocommit trouble with jdbc on Postgres 7.4

PostgreSQL 7.4 no longer supports server side SET AUTOCOMMIT TO OFF,
thanks to Tom Lane. Problem is my java application server now breaks.
When I try to save a record in the database, I get
"java.sql.SQLException: ERROR:  SET AUTOCOMMIT TO OFF is no longer
supported".  <fontfamily><param>Verdana</param>The code that sends
this is jdbc compliant and works with about a dozen other rdbms
including postgresql7.3. Isn't he whole point of jdbc to make it so
clients don't need to be rewritten each database??? Please don't tell
me to change my code code - it isn't mine and I can't.</fontfamily>


Questions:


1) Does this mean that the jdbc driver that ships with pg7.4 isn't up
to speed with the new autocommit change? What about the 7.4
development version of the driver? Does it properly handle the SQL for
the new 7.4 change? I tried it and it also failed, but maybe I
installed it improperly. I simply replaced the existing postgresql.jar
file with the <fontfamily><param>Lucida Grande</param>devpgjdbc3-1.jar
(renamed as</fontfamily> postgresql.jar) and restarted. Didn't work.


2) is there a version of the jdbc driver that won't send "SET
AUTOCOMMIT TO OFF" to the postgresql7.4 server when I use
    <fontfamily><param>Verdana</param>Connection.setAutoCommit(false)


3) If there is a driver that works, do I need to do something other
than just replacing the existing </fontfamily>postgresql.jar file? I'd
assume the classpath etc would be the same it that case, but I've
tried it building 7.4 --with-java from scratch and also tried the SuSE
7.4 RPM in addition to replacing the jar file as mentioned. Each fails.


Any clues appreciated. Thanks in advance!
