我在JSP中写到:(代码片断）

Connection conn = cgclass.getConn();
Statement stmt = conn.createStatemen(ResultSet.TYPE_SCROLL_INSENSITIVE,ResultSet.CONCUR_UPDATABLE);
String sql = \"select distinct SELL_ORG_ID,SELLING_ORG_NAME,city,area_id from new_fmt_supplier order by city\";
ResultSet rs = stmt.executeQuery(sql);
pages=rs.getFetchSize()/20;

    rs.absolute(row*20+1); 为什么这句话抛异常！（方法不支持，为什么不支持啊 我有设置滚动结果集啊）
        for(int i=0;i<20;i++){
            rs.next();
            String SELL_ORG_ID = rs.getString(\"SELL_ORG_ID\").trim();
            String SELL_ORG_NAME = rs.getString(\"SELLING_ORG_NAME\").trim();
            String city = rs.getString(\"city\").trim();
            String area_id = rs.getString(\"area_id\").trim();
        something...
        }

异常如下：

这个问题貌似有前辈问过了，可以查查以前的帖子

看了下面一个示例可能对你有所帮助

conn.jsp
＜%
String sDBDriver = "COM.ibm.db2.jdbc.app.DB2Driver";
String sConnStr = "jdbc:db2:faq";
Connection conn = null;
Statement stmt = null;
ResultSet rs=null;
try {
Class.forName(sDBDriver);
}
catch(java.lang.ClassNotFoundException e) {
out.print("faq(): " + e.getMessage());
}

try{
conn = DriverManager.getConnection(sConnStr,"wsdemo","wsdemo1");
stmt = conn.createStatement();
}catch(SQLException e){
out.print(e.toString());
}
%＞

query.jsp

＜%@ page language="java" import="java.sql.*" %＞
＜%@ page contentType="text/html; charset=gb2312" %＞
＜%@ include file="conn.jsp" %＞
＜%
.......
int pages=0;
int pagesize=10;
ResultSet result = null;
ResultSet rcount = null;

pages = new Integer(request.getParameter("pages")).intValue();

if (pages＞0)
{

String sql=" state=´我不傻´";
int count=0;
try {
rcount = stmt.executeQuery("SELECT count(id) as id from user where "+sql);
catch(SQLException ex) {
out.print("aq.executeQuery: " + ex.getMessage());
}
if(rcount.next())
count = rcount.getInt("id");
rcount.close();

if (count＞0)
{
sql="select * from user where "+sql;
try {
result = stmt.executeQuery(sql);
}
catch(SQLException ex) {
out.print("aq.executeQuery: " + ex.getMessage());
}

int i;
String name;
// result.first();
// result.absolute((pages-1)*pagesize);
// 此方法jdbc2.0支持。编译通过，但执行不过，不知是不是跟驱动有关，只好用下面的笨办法。
for(i=1;i＜=(pages-1)*pagesize;i++)
result.next();
for(i=1;i＜=pagesize;i++) {
if (result.next()) {
name=result.getString("name");
out.print(name);
}
result.close();
int n= (int)(count/pagesize);
if (n*pagesize＜count) n++;
if (n＞1)
{
for(i=1;i＜=n;i++)
out.print("＜a href=query.jsp?pages="+i+"＞"+i+" ＜/a＞");
}
}
}

楼上大哥，能不能解释一下红色部分啊？看不大明白啊！
