巧用jsp页面用表单实现动态打印功能

1,首先,在jsp页面中加入打印组件:
<object id="WebPrint" classid="clsid:B3C860B8-1EDD-4BBF-B8A4-74238982457A" height=10 width=100 align="center" hspace=0 vspace=0></object>
加入打印事件表单:
<form id="frmPrint" name="frmPrint" method="post" action="">
<input name="DepositPreview" type="submit" id="DepositPreview" value="print" onClick="PreviewDeposit();"/>
</form>
2,引入打印后台逻辑类,<%@ page import="WebPrint.PrintFunction"%>,


3,调用javaBean:<jsp:useBean id="pf" scope="page" class="WebPrint.PrintFunction"/>
4,加入js打印函数:调用后会重新刷新页面;
function PreviewDeposit(){
document.frmPrint.action="materialDetailList.jsp?PrintType=DepositPreview";
document.frmPrint.submit();
}
5,加入jsp打印控制逻辑,用out动态输出真正实现打印的js:
<%
String PrintType=request.getParameter("PrintType");
String ReportPath="d:\\jy\\jboss-3.5-DDDO\\server\\default\\deploy\\stringbeans.war\\Mis\\materialMng\\materialPlan\\";


System.out.println(PrintType);
if(PrintType==null){
}else if(PrintType.equals("DepositPreview")){
//pf.OpenDataConnection();
String PrintValue="111111111";//pf.TableToXml("select top 1 * from gdms.t_reqmaterial");
String FileValue=pf.FileToStr(ReportPath+"MaterialDetail.fr3");
System.out.println("FileValue:"+FileValue);
String ParaName="ShopName`~PrintDepositAdd`~PrintPaperNo`~Title";
String ParaValue="测试酒店"
