jdbc problem

Hi.

I use ibatis and jdbc do connect to postgres. When I use a 8.2 database,
then all works ok, but for 7.4 databases I get this error:

15:42:46,936 INFO [STDOUT] 2007-08-22 15:42:46,932 B5A22F41 WARN

When i check the servers logs i see this:
LOG: connection received: host=192.168.1.16 port=52557
LOG: connection authorized: user=postgres database=gwind
LOG: connection received: host=192.168.1.16 port=43021
LOG: connection authorized: user=postgres database=gwind
LOG: statement: BEGIN
LOG: statement: create
ERROR: syntax error at end of input at character 10
LOG: statement: ROLLBACK
LOG: statement: create
ERROR: syntax error at end of input at character 10
LOG: statement: create
ERROR: syntax error at end of input at character 10
LOG: statement: create
.....
this ERROR repeats every 3 seconds.

When i send a request to the servlet, i get this on the log:
LOG: statement: SET SESSI
ERROR: syntax error at end of input at character 10

I really try to :
----- Change the JDBC jar file for postgres 7.4 and 8.2
----- use additional options on the url connection

My database is in LATIN2.

Thanks.
