Hi,
my recent webapp is supposed to generate PDF reports. Because I don't know
much about JasperReports, I've outsourced the functionality to a
freelancer.
He created separate module (jar) that provides desired functionality.
Part of maven structure of my project looks like this:
- ngo
|---- ngo.pdf
|---- src
|---- resources
|---- DOCOferta.jrxml
|---- ngo.webapp
where ngo.pdf is this outsourced functionality and ngo.webapp is Wicket
webapplication.
Now the problem. Freelancer created this piece of code:
public InputStream generate() throws GenerationException {
Map<String, Object> parameters = new HashMap<String, Object>();
// here parameters
JRProperties.setProperty("net.sf.jasperreports.default.pdf.encoding",
"UTF8");
try {
URL resource =
getClass().getClassLoader().getResource("DOCOferta.jrxml");
InputStream inputStream = resource.openStream();
JasperDesign design = JRXmlLoader.load(inputStream);
This code works great when run in tests of ngo.pdf but when I try to run
generate() method from Wicket (as part of ResourceLink) I get
NullPointerException at
InputStream inputStream = resource.openStream();
So I get that that the resource "DOCOferta.jrxml" is not found. But the
question remains, how to get this work?
What should I do to achieve this result:
- generate() will not throw NPE, it will generate pdf report [A MUST :)]
- all resources needed to create PDF (all the *.jrxml files) stay inside
inside ngo.pdf jar (inside the resource folder) [DESIRABLE]
I will appreciate any form of help.
Best regards,
Paul Szulc
