Hi Andrea The patch in that boards post is applied to the latest devel archive already, and the sources would have changed since then so it is not surprising that it fails to apply. So it would appear your error is occurring for another reason or you are picking up and old version of the JDBC Driver, thus can you please confirm the driver version in use with the command:
java virtuoso.jdbc3.Driver
which should return something like:
$ java virtuoso.jdbc3.Driver
OpenLink Virtuoso(TM) Driver for JDBC(TM) Version 3.x [Build 3.62]
$
Best Regards
