Hi All, i got an error while running this portion of my code. CODE String url = "http://localhost/testing.jsp"; String query = "home\funiture"; JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, new net.sf.jasperreports.engine.data.JRXmlDataSource(url, query)); ERROR net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: No query executer factory class registered for xpath2 queries. net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: No query executer factory class registered for xpath2 queries. I search through the forum but still could not understand how to add in the xpath2 query executer factory class. I added the jasper-extention jar into my project already and it does not help. Anyone who has solved this issue can gimme a hand.??
