>  JRXmlDataSource xmlDataSource = new JRXmlDataSource(doc.getDocumentURI(),"/userData M55_USERS_NEW");

that can just be:

 JRXmlDataSource xmlDataSource = new JRXmlDataSource(doc ,"/userData M55_USERS_NEW");

you can avoid parsing the xml yourself though and just pass the file path directly to the data source

did you make the change I suggested above?

or alternatively

 JRXmlDataSource xmlDataSource = new JRXmlDataSource(application.getRealPath("/reports/userxml.xml") ,"/userData M55_USERS_NEW");

Actually i read the this from jasper report pdf that
JRXmlDataSource contains other constructors that allow us to send the XML document as an org.w3c.dom document, as a java.io file, or as a String containing a Uniform Resource Identifier (URI)


JRXmlDataSource xmlDataSource = new JRXmlDataSource(doc ,"/userData M55_USERS_NEW");


that why i gave as document as in construtor  so this is not taking
and i want to used for jasper report so that i did the parsing of xml...

if u have any code then please give me its urgent

sorry your right, it would be:

 JRXmlDataSource xmlDataSource = new JRXmlDataSource(new File(application.getRealPath("/reports/userxml.xml")) ,"/userData M55_USERS_NEW");

but you still need to work out what select expression you need

I do understand that. From what you have said it is inside that method attempting to load the data source
I can't tell you what the select expression is as it is related to your data

I pointed out what the problem was, there is no way I can tell you what the select expression should be. Only you can determine that.
