sybase jdbc connection issue

Question

Я просто новичок в сибасе. я пытаюсь сделать простое подключение jdbc к моему серверу sybase. используя нижеприведенный код.

У меня есть jcon3.jar в моем classpath тоже.

try { 
     Class.forName("com.sybase.jdbc3.jdbc.SybDataSource"); 
     System.out.println("before connection"); 
     Connection conn = DriverManager.getConnection("jdbc:sybase:Tds:localhost:1326/db","butt","clear"); 
     System.out.println("after connection"); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 

Я не могу достичь того, чего ожидаю. ниже - ошибка, которую я получаю.

inside try 
before connection 
java.sql.SQLException: JZ00L: Login failed. Examine the SQLWarnings chained to this exception for the reason(s).

SQL Error : State=[JZ00L] JZ00L: Login failed. Examine the SQLWarnings chained to this exception for the reason(s). 
SQL Error : State=[JZ0IB] JZ0IB: The server's default charset of roman8 does not map to an encoding that is available in the client Java environment. Because jConnect will not be able to do client-side conversion, the connection is unusable and is being closed. Try using a later Java version, or try including your Java installation's i18n.jar or charsets.jar file in the classpath. 
SQL Error : State=[JZ006] JZ006: Caught IOException: java.io.CharConversionException: java.io.UnsupportedEncodingException: hp-roman8

1. Скачать последнюю версию компании Sybase драйвера.
