sybase jdbc 연결 문제

Question

저는 sybase에서 초보자입니다. 내 sybase 서버에 간단한 jdbc 연결을 시도하고 있습니다. 아래 코드를 사용하십시오.

내 수업 경로에도 jcon3.jar이 있습니다.

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(); 
    } 

내가 기대하는 것을 달성 할 수 없습니다. 아래에 내가 받고있는 오류입니다.

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
