database server connection

I need to connect this server database to Servoy:

Sybase SQL Anywhere Database Engine Version 5.5.04 Build #1867

Start time: Mon Sep 07 2009 16:28
Transaction log: HOTELSINGLEV200602.LOG
Starting checkpoint: Mon Sep 07 2009 16:28
Finished checkpoint: Mon Sep 07 2009 16:28
Database: C:\PROGRA~1\eversafe\HOTELM~1.01\HotelSingleV200602.Db started

Its default collation is Code page 850 latin 1.

I’ve tried with default parameter, with this URL string:

jdbc:sybase:Tds:localhost:2638?ServiceName=HotelSingleV200602&CHARSET=utf8

Servoy (the JDBC default drive) gives this error:

org.apache.commons.dbcp.DbcpException: java.sql.SQLException: JZ00L:
Login failed. Examine the SQLWarnings chained to this exception for
the reason(s).

I’ve tried in several ways to set the Charset to latin 1, if it helps, but with no results, the error changes like that:

org.apache.commons.dbcp.DbcpException: java.sql.SQLException: JZ0I5:
An unrecognized CHARSET property was specified: Latin1.

What should I do to set the right collation and to connect to the database?

luigicorte:
org.apache.commons.dbcp.DbcpException: java.sql.SQLException: JZ00L:
Login failed. Examine the SQLWarnings chained to this exception for
the reason(s).

This means that the username/password combination is not correct.
Note that Sybase 10 is case sensitive in username/passwd by default.
