Re: About a JDBC error

> so if your driver is older than that, it may be the problem.
I use the JDBC  drive in package : postgresql-jdbc-7.4.1-1PGDG.i386.rpm.
And I user md5 in pg_hba.conf.
I think my default encoding is EUC-JP.

Do you think if I update my JDBC Driver , the error will go away?
This problem is so difficult to me. (-_-)b
