sybase jdbc連接問題

Question

我只是sybase的初學者。 正在嘗試建立與我的sybase服務器的簡單jdbc連接。 使用下面的代碼。

我的類路徑中也有jcon3.jar。

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();
    }

我無法達到我的期望。 以下是我得到的錯誤。

inside try
before connection

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

Answer 1

1. 下載Sybase最新版本的驅動程序。
2. 包括Sybase驅動程序的i18n.jar和/或charsets.jar。
