WEB打印问题，求教？？？

各位大佬，先有些问题想要请教，最近做的项目涉及到WEB打印问题，请教各位有没有什么好的建议或者是控件，我的开发环境是MyEclipse5.5+Tomacat5.5 基于MVC的框架结构，现在在WEB打印这里不知道该如何下手，有这方面的朋友们帮忙解决下呀，传统的打印我已经试过，无法控制页面的大小。主要因为有一个打印格式需要自定义，求教各位了。谢谢！！！！

忘记提一点的是，我的报表是用JasperReport与 iReport 制作的。

一般问题我可以帮你解决！
用iReport 吧.我也做过这方面的东西.不过你要熟悉iReport 报表工具,知道怎么样来画你自己想要打印的报表.具体代码我会给你提供一些.一般在页面点打印的时候触发一个window.open()事件,
  eg:
      window.open("目录/test.jsp?id=1);
然后在test.jsp里面加入以下代码:
       <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
  <head>
    <title>测试</title>   </head>
  <script lanuage="javascript">
   
  </script>
  <body onunload="unLoadReportSession();"  onload ="loadReport()" leftmargin="0" topmargin="0" rightmargin="0">
   <form id ="frm" >
   </form>
  <%
  int id;
     id=Integer.parseInt(request.getParameter("id"));
       String reportFile ="/report/iReport/test.jasper";
    String params="dispatch=test&reportFile="+reportFile+"&id="+id;
   %>
    <OBJECT classid="clsid:8AD9C840-044E-11D1-B3E9-00805F499D93" WIDTH = "100%" HEIGHT = "100%"  codebase="<%=request.getContextPath()%>/j2re.exe#Version=5,0,0,5"><NOEMBED></NOEMBED>

<APPLET  CODE = "EmbeddedViewerApplet.class" NAME ="testApplet" CODEBASE ="<%=request.getContextPath()%>/applets" ARCHIVE = "jasperreports-applet.jar,jasperreports.jar" WIDTH = "100%" HEIGHT = "100%">
<PARAM NAME = CODE VALUE = "EmbeddedViewerApplet.class" >
<PARAM NAME = CODEBASE VALUE = "<%=request.getContextPath()%>/applets" >
<PARAM NAME = ARCHIVE VALUE = "jasperreports-applet.jar,jasperreports.jar" >
<PARAM NAME="type" VALUE="application/x-java-applet;version=1.5">
<PARAM NAME="scriptable" VALUE="false">
<PARAM NAME = "REPORT_URL" VALUE ="<%=request.getContextPath()%>/testAction.do?<%=params%>">
</APPLET>
</OBJECT>
  </body>
</html>
里面有几个东西你需要替换成你自己的,第一参数,第二你将要处理的ACTION,这里用的是testAction.do.其他主要就在下个action里面处理了.
testAction:
public ActionForward test(ActionMapping mapping, ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
       Map parameters = new HashMap();
       int id;
       String strSQL = "select * from test where id="+id;
       parameters.put("strSQL",strSQL);
    //下面的你不用动,只要上面你把自己的参数和sql放到map里面.
     ServletContext context = this.getServlet().getServletContext();

        String reportFilePath = request.getParameter("reportFile");
        File reportFile = new File(context.getRealPath(reportFilePath));
     JasperPrint jasperPrint = null;
     Connection conn =dataSource.getConnection();
        try
        {
            JasperReport jasperReport = (JasperReport)JRLoader.loadObject(reportFile.getPath());            jasperPrint =
                JasperFillManager.fillReport(
                    jasperReport,
                    parameters,
                    conn
                    );
      //将这个报表结果存入session中给后来的导出报表使用。
      request.getSession().setAttribute("jasperReport",jasperPrint);       }
        catch (JRException e)
        {
            response.setContentType("text/html");
            PrintWriter out = response.getWriter();
            out.println("<html>");
            out.println("<head>");
            out.println("<title>JasperReports - Web Application Sample</title>");
            out.println("<link rel=\"stylesheet\" type=\"text/css\" href=\"../stylesheet.css\" title=\"Style\">");
            out.println("</head>");            out.println("<body bgcolor=\"white\">");            out.println("<span class=\"bnew\">JasperReports encountered this error :</span>");
            out.println("<pre>");            e.printStackTrace(out);            out.println("</pre>");            out.println("</body>");
            out.println("</html>");
        } finally {
         try {
       if (conn!=null) {
         conn.close();
         }
         } catch (SQLException e) {
         e.printStackTrace();
         }
        }

        if (jasperPrint != null)
        {
            response.setContentType("application/octet-stream");
            ServletOutputStream ouputStream = response.getOutputStream();            ObjectOutputStream oos = new ObjectOutputStream(ouputStream);
            oos.writeObject(jasperPrint);
            oos.flush();
            oos.close();            ouputStream.flush();
            ouputStream.close();
        }
        else
        {
            response.setContentType("text/html");
            PrintWriter out = response.getWriter();
            out.println("<html>");
            out.println("<head>");
            out.println("<title>JasperReports - Web Application Sample</title>");
            out.println("<link rel=\"stylesheet\" type=\"text/css\" href=\"../stylesheet.css\" title=\"Style\">");
            out.println("</head>");            out.println("<body bgcolor=\"white\">");            out.println("<span class=\"bold\">Empty response.</span>");            out.println("</body>");
            out.println("</html>");
        }
return null;
}
其实这样后续还是报表设计了.代码部分就这些,建议先把ireport弄熟悉再做吧.也很简单的.
