Strange exception on JasperFillManager.fillReport()

[dosadi]

Hi, I am getting an exception calling JasperFillManager.fillReport() that I am having trouble tracking down a good description of:

point a

point b

point c

Here is the generating code:

JasperDesign jasperdesign = null;

try {

if (doctype.contentEquals("weekly")) {

jasperdesign = JRXmlLoader.load("/root/weeklyReport.jrxml");

} else if (doctype.contentEquals("monthly")) {

jasperdesign = JRXmlLoader.load("/root/monthlyReport.jrxml");

} else if (doctype.contentEquals("custom")) {

jasperdesign = JRXmlLoader.load("/root/customReport.jrxml");

}

// else if (doctype.contentEquals("single"))

// {

// jasperdesign = JRXmlLoader.load("/root/weeklyReport.jrxml"); //

}

else {

throw new Exception("Unknown content type " + doctype.toString());

}

} catch (JRException e2)

{ // TODO Auto-generated catch block e2.printStackTrace();

} catch (Exception e)

{

// TODO Auto-generated catch block e.printStackTrace();

}

System.err.println("point a");

JasperReport jasperreport = null;

try {

jasperreport = JasperCompileManager.compileReport(jasperdesign);

}

catch (JRException e)

{

// TODO Auto-generated catch block e.printStackTrace();

}

System.err.println("point b");

JRXmlDataSource jrxmldatasource = null;

try

{

jrxmldatasource = new JRXmlDataSource("tempfile.tmp");

} catch (JRException e1)

{

// TODO Auto-generated catch block

e1.printStackTrace();

}

System.err.println("point c");

JasperPrint jasperprint = null;

try {

jasperprint = JasperFillManager.fillReport(jasperreport, null, jrxmldatasource); }

catch (JRException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

System.err.println("point d");

 

I am not sure why a groovy-related class is being invoked, since I have explicitly set the language="java" in the .jrxml file used. Is there a global setting somewhere for the language= parameter?

Hi,

From the error I guess the problem is with your Xml Data Source.

Why do you use a .tmp file? Shouldn't it be an xml file? It seems that the loaded document is null:

The supplied org.w3c.dom.Document object is null: If you check the javadoc this interface is related to xml files so the problem happens when you try to load the tempfile.tmp file.

Don't know if JRXmlDataSource supports another kind of file but I think it should be an xml file.

Hope this helps.

Regards.
