Hi,

  It seems JDBCRealm implementation calls Conneciton.setAutoCommit() method
automatically. So your MySQL Server need to be able to accept SQL statements
"SET AUTOCOMMIT=1;" or "SET AUTOCOMMIT=0;"
  Please check it with mysql console client.

  In my case, MySQL-Max(InnoDB) 3.23.49 and gweMysql JDBC Driver and
Tomcat4.0.3, JDBCRealm works fine.

Thanks.
