I don't have a specific answer for you, but I'm a beginner too, and I had the same problem. I fixed it by trying different values for the XPath strings for the data source and the report XPath queries. In my case, I had an outer XML element with various different elements inside, but not repeating items. I'm using iReport to design the report.

 

In the data source text field labeled "Create data source using this expression", I specified /outerElementName (where "outerElementName" is whatever your outer element name is). Then in the report query dialog I specified XPath as the query language, and specified * as the query string.

 

I have a subreport with repeating elements. For that one, I got it to work by specifying /outerElementName/repeatingElementName in the data source, and outerElementName/repeatingElementName (notice the absence of the leading slash) for the report query.

 

This worked for me, but I'd be curious to know if there's a better way.

As i have just  created a sample report with no data to be displayed just a static text.....i was just filling the report like this....

jasperPrint = JasperFillManager.fillReport(jasperReport, null);

but as there is an empty datasource, i have supplied another parameter in it with empty datasource....

jasperPrint = JasperFillManager.fillReport(jasperReport, null, new JREmptyDataSource());

now it is working fine for me..
