Question

我只是sybase的初学者。我正在尝试与我的sybase服务器建立一个简单的jdbc连接。使用下面的代码。

我的类路径中也有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();
    }

我无法实现我的期望。以下是我得到的错误。

inside try

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

下载Sybase最新版本的驱动程序。
包括Sybase驱动程序的i18n.jar和/或charsets.jar。
