can't preview document (xml source). Error filling print

[victorsambist]

I use xml datasource. I ve made several fields, put in them data from xml - data-source (with XPath metchod).

Then I compile document, everything is right. And then iReport has announced error like this:

Error filling print... XPath compilation failed. Expression:

Print not filled. Try to use an EmptyDataSource...]

I ve change files in dicrectoru ireport/libs like Xalan and others, how it advised in forums, but nothing has helped me. 

I have tryed to use diffirent versions of programm, but in vain. Maybe IReport can't work with xml datasource at all?

Can you help me?

 

[netti royala]

can you provide JRXML File ?

[nicolaifriis]

The exceptions tell us that there is a syntax error in one or more of your XPath expressions. XPath expressions are compiled runtime, not when you compile the report.

Hellow netti royala, I ve sent JRXML file.

Hello nocolaifriis, i ve sent file, where you can see stages of my making of report
