[FIXED] convert date from MM/dd/yyyy to MMddyyyy only while downloading PDF format

Issue

I have a servlet code written as shown below,where I am passing the parameters through map function and I have to download the report in PDF format,where while downloading i have to add to my request.getparameter("param2") to request.getparameter("param1") with formatting date as MMddyyyy because it doesn't accept "/" while downloading the file.

Please try to help me with this query,Thank's in advance.

SimpleDateFormat dateFormat2 = new SimpleDateFormat("MM/dd/yyyy");
 Map<String, Object> map = new HashMap<String, Object>();
     map.put("Course_ID", request.getParameter("param1"));
     map.put("StartDate", dateFormat2.parse(request.getParameter("param2")));
     map.put("EndDate", dateFormat2.parse(request.getParameter("param3")));

     JasperReport jr = JasperCompileManager.compileReport(jrxmlFileName);
     JasperPrint jp = JasperFillManager.fillReport(jr, map, conn);
     JasperExportManager.exportReportToPdfFile(jp,
          "D:/ForReports/Downloads/" + request.getParameter("param1") +".pdf");

 System.out.println("Done exporting pdf format to view");

And in html parameters will be getting passed as shown,

<div class=" col-sm-3" class="form-group">
<br>
<p align="center" ><a  class="btn icon-btn btn-info"  ng-href="JasperServlet2?param1={{modelcourse}}&param2={{formatDate(startdate) |date:'MM/dd/yyyy'}}&param3={{formatDate(enddate) |date:'MM/dd/yyyy'}}" target="_blank"><span class="glyphicon btn-glyphicon glyphicon-print img-circle text-success"></span>&nbspClick Here To View report</a></p>
</div>  

Solution

Hope this code may help :-

String date=request.getParameter("param1");
date=date.replaceAll("/", "");
JasperExportManager.exportReportToPdfFile(jp,
      "D:/ForReports/Downloads/" + date +".pdf");

while other code will remain same.
