2个子报表就可以了！ surReport
你将上面的拆分成3个文件。
一个是:数据库操作文件，比如你连接数据，查询的SQL语句，直接返回一个ResultSet(建议不要直接返回ResultSet的对象,可以返回一个List,或者Iterator)。然后在第二个源文件中去遍历。二个是：由于你的Kline.jsp和K.jsp中的代码有所不同，你可以将他们分别写入对应的.java文件。
将Kline.jsp内容复制到Kline.java中
将K.jsp内容复制到K.java中记住一点在.java文件中创建图形的方法必须要有HttpSession session, PrintWriter pw这2个参数。后面在说
看红色表示的
public String createTimeSeriesChart(HttpSession session, PrintWriter pw) throws SQLException
{
   .....................................
}
Kline.jsp:
String filename = ServletUtilities.saveChartAsPNG(chart, 500, 300, null, session);
K.jsp
String filename = ServletUtilities.saveChartAsPNG(chart, 500, 300, null, session);三个是：建一个.jsp页面加入代码如下
<div id="jiange">
<%

Kline line=new Kline();
String filename1 = line.createTimeSeriesChart(session,new PrintWriter(out));
String graphURL1 = request.getContextPath() + "/servlet/DisplayChart?filename=" + filename1;
%>
<img src="<%=graphURL1%>" border=1 usemap="#<%=filename1%>"><br><br>
<%
K k=new K();
String filename = k.getPieChart(session,new PrintWriter(out));
String graphPieplotURL = request.getContextPath()+ "/servlet/DisplayChart?filename=" + filename;
%>
<img src="<%=graphPieplotURL%>" border=0 usemap="#map0">
</div>
以上是我以前做项目。一个页面显示2个图，一个曲线图，一个饼图。只提供了思路，具体的方法还要自己去实现。。
