jdbc-odbc 中 取记录集必须按照字段顺序。。。晕
即 select *  from notebook 
检查一下下句：是否是按照字段顺序？
while (rs.next()) {
int id=rs.getInt("id");
username= rs.getString("username");
email= rs.getString("email");
doc=rs.getString("doc");
url=rs.getString("url");
date=rs.getString("date");
。。。
}

把你的Statement换成conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_READ_ONLY）试试

最好不要用select * 这种写法，在SQL文中把所有的列名都写出来，这样的话取值就可以随意了，不需要按照顺序了，你试试看，不行在想办法。

如果ResultSet中字段為id,a的話,在調用rs.getString("a"),不能再調用rs.getInt("id"),也就是說不能向后查詢.因為你的結果集是只向前滾動的.

把你的dbconn类也贴出来看看！
