Way of printing Jasper Report at client side

Hi friends,

I have developed one project which is customised Jasper Reports with export and print options.
I haven't get any problem for export options.
Coming to Print, i found that it is printing at server end.
So to eliminate that problem i found one solution that will be printing at client side.

For this solution i have used Jasper Report object and Ajax functionality.
The code is like this:
1) In my JSP



<input type="button" class="button_submit" value="print" onclick="javascript:print();">


Handler: For a "Print" Button you need to add onclick listener function print();


function print()
{
/* ========== AJAX Initializtion ========== */
xmlhttp = false;
if (window.XMLHttpRequest) {// code for Firefox, Opera, IE7, etc.
xmlhttp=new XMLHttpRequest();
} else if (window.ActiveXObject) {// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
/* ========== AJAX Initializtion ========== */

if (xmlhttp!=null) {
url = "/mms/reports";
xmlhttp.onreadystatechange= function () { getWorkReqDivs(xmlhttp); };
xmlhttp.open("POST", url, true);
xmlhttp.setRequestHeader("Cache-Control","no-cache, private, max-age=0");
xmlhttp.send(null);

} else {
alert("Your browser does not support XMLHTTP.");
}
}
function getWorkReqDivs(httpRequest1)
{
if(httpRequest1.readyState==4)
{
if(httpRequest1.status==200)
{
var result = httpRequest1.responseText;
var disp_setting="toolbar=yes,location=no,directories=yes,menubar=yes,";
disp_setting+="scrollbars=yes,width=650, height=600, left=100, top=25";
var content_vlue=result;
var docprint= window.open("", "", disp_setting);
docprint.document.open();
docprint.document.write(&lthtml>);
docprint.document.write(<body onLoad="self.print()">&lt

/body>
&lt
/html>);

docprint.document.write(content_vlue);

docprint.document.close();
docprint.focus();

}
}
}

This script is used to get the Jasper Report in HTML format as responseText. So this text is added in window.open().It looks like print preview.In onload itself print dialog box will come to ask print.


Struts-config.xml


<action path="/mms/reports" type="com.km.bp.mms.jsperReports.printAction"> 
<forward name="print" path="/WEB-INF/jsp/jasperReports/print.jsp"/>
</action>


Java Class: (printAction.java)


JRHtmlExporter exporter = new JRHtmlExporter();

String jrept = "indentReport.jrxml";

String reportFileName = JasperCompileManager.compileReportToFile(request.getRealPath("/reports") + "/" + jrept);

java.util.Map parameters = new java.util.HashMap();

Connection con = MMSDB.getConnection();String fromDatet="01/01/2010";String toDate="28/02/2010";

parameters.put("fromDate", fromDatet);parameters.put("toDate", toDate);

File reportFile = new File(reportFileName);if (!reportFile.exists()) {throw new JRRuntimeException("File WebappReport.jasper not found. The report design must be compiled first.");
}

JasperPrint jasperPrint = JasperFillManager.fillReport(reportFileName, parameters, con);

PrintWriter out = response.getWriter();response.setContentType("text/html");

exporter.setParameter(JRExporterParameter.JASPER_PRINT, jasperPrint);

exporter.setParameter(JRHtmlExporterParameter.OUTPUT_WRITER, out);

HashMap fontMap = new HashMap();

exporter.setParameter(JRHtmlExporterParameter.FONT_MAP, fontMap);

exporter.setParameter(JRHtmlExporterParameter.IS_WHITE_PAGE_BACKGROUND, Boolean.FALSE);

exporter.setParameter(JRHtmlExporterParameter.IS_USING_IMAGES_TO_ALIGN, Boolean.FALSE);

exporter.setParameter(JRHtmlExporterParameter.IS_REMOVE_EMPTY_SPACE_BETWEEN_ROWS, Boolean.TRUE);

exporter.setParameter(JRHtmlExporterParameter.IS_WRAP_BREAK_WORD, Boolean.TRUE);

request.setAttribute("exportIndentObject", exporter);

return mapping.findForward("print");}

}


  



Jsp File :(print.jsp)( The following Jsp is the responseText of the Ajax Call)


<%@page import="net.sf.jasperreports.engine.export.JRHtmlExporter" %>

< % JRHtmlExporter export = (JRHtmlExporter) request.getAttribute("exportIndentObject"); session.setAttribute("exportIndentObject", export); JRHtmlExporter export1 = (JRHtmlExporter) session.getAttribute("exportIndentObject"); export.exportReport(); %>

    Hi there,

    I'm facing today the same problem as yours.

    But instead of struts, i'm working with jsf.

    Is there a solution for my problem ?

    Hi Midos,

    I tried to implement. But it will take some more time. Because i am not familiar with JSF.
    After successful completion i will post ur problem in my blog.

    No.No.
    "MMSDB" is a public class.In that i have written steps to connect with database.
    Instead of that(MMSDB) you can use like this
    Connection conn = DriverManager.getConnection(url,"user1","password");

    Hi,

    Do you want to send request to server by clicking Print button? (Means handling printer through server side) or client side (through javascript)?

    If u want to print web page data through javascript , code is in the following URL.Please check javascript code

    http://helptodeveloper.blogspot.com/2010/02/way-of-printing-jasper-report-at-client.html

    Its like you read my mind! You seem to know so much about this, like you
    wrote the book in it or something. I think that you can do with a few pics to drive
    the message home a little bit, but other than that,
    this is wonderful blog. A great read. I will definitely
    be back.
