warning message

[mathewrond]

Hi,

This is my java code

 

public static void main(String args[])

{

try

{

Map params = new HashMap();

params.put("ReportTitle", "Orders Report");

Document document = JRXmlUtils.parse(new File("D:\eclipse\workspace\JasperPOC\config\sample.xml"));

 

params.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, document);

System.out.println("3");

JasperReport jasperReport = (JasperReport)JRLoader.loadObject("D:\eclipse\workspace\JasperPOC\config\land_report_1.jasper");

System.out.println("33");

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params);

System.out.println("4");

jasperPrint = moveTableOfContents(jasperPrint);

 

File destFile = new File("D:\eclipse\workspace\JasperPOC\config\land_report_1.jrprint");

JRSaver.saveObject(jasperPrint, destFile.toString());

 

JasperExportManager.exportReportToPdfFile("D:\eclipse\workspace\JasperPOC\config\land_report_1.jrprint");

 

}catch(Exception e){ e.printStackTrace(); }

}

 

and I get the following message

 

Aug 28, 2006 6:23:27 PM net.sf.jasperreports.engine.query.JRXPathQueryExecuter <init>

WARNING: The supplied org.w3c.dom.Document object is null.

 

And the problem is at this line

JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params);

 

Can someone help me out with what the problem could be?

I guess document is null.

 

You can easily check it via the debugger in Eclipse.

I have printed the XML file using Document object and it prints me all the information in the XML file.

 

 

I have also got the PDF file generated with the data.

 

 

What I was trying to achieve is to generate a PDF file with summary page on the first page.

 

 

I have got 4 .jrxml files.

 

 

e.g.

main.jrxml

summary.jrxml

header.jrxml

detail.jrxml

 

main.jrxml includes both header.jasper and summary.jasper.

 

Is this creating any problem?

 

Please give me some ideas.

[Alexander Merz]

I'm not sure why you want the summary section at the top of the report.

 

Could it be possible, that you just want to set the evalutionTime attribute of a <textField> to the value "Report"?

 

Then the expression in <textFieldExpression> is evaluated when reaching the end of the report.

[mathewrond]

Yes its possible to have summary page on top of the report. There is an example of Table of contents

provided with jasper reports software.

 

I have the current problem while implementing the logic.

[Alexander Merz]

Nitpick: It is not possible to move the summary *section* at the top. But you can move a page having a specific text to another position.

 

But this is not the problem here, the exception is thrown before moveTableOfContents() is called.

 

I feel a little out of context. The warning does occur in your real application? The given code is only a demonstration?

 

In your demo you don't provide any references to the sub reports. I guess JasperReports can successfully load main.jrxml, but fails while trying to load the files for the sub reports.

[mathewrond]

I guess you are true. I have searched the forums and found a solution to implement what I am actually looking at.

 

Thank you for your support.
