为什么我一直无法Update我的表?

[sunnyasp]

我的表是在Sybase服务端上,不在本地,有读写权限.

错误提示信息为:java.lang.AbstractMethodError: com.sybase.jdbc.SybConnection.createStatement(II)Ljava/sql/Statement;

代码如下:
try
{
Class.forName("com.sybase.jdbc.SybDriver"); Connectionconn=DriverManager.getConnection"jdbc:sybase:Tds:192.168.0.250:4100/fct_edi", "sa", "fqctos");
Statement stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
ResultSet rs = stmt.executeQuery("select * from Tmptable");
rs.updateString("fname","dsfsa");
rs.updateString("fage","3");
rs.updateRow();
rs.close();
stmt.close();
}
catch(Exception sqle)
{
sqle.printStackTrace();
}
