Hello, -------------------- Can you please shed some light on the props files.?.. where exactly should we create and keep Properties file in application? -------------------- That's the JasperReports.properties file which is the configuration file for JR. It can contain different options and export hints and stuff like that. The file can be read from the file system, accessed as a resource from the classpath, or loaded from an URL. The default name of the properties file is jasperreports.properties. If you want to specify the different source then you need to alter net.sf.jasperreports.properties system property and specify a different file name or location. The default or custom name is successively interpreted as a file name, a resource name, and an URL; the properties are read from the first succeeding source. If you need to access that property at runtime at runtime you need to use the class called net.sf.jasperreports.engine.util.JRProperties and it's static methods. -------------------- Also how will our application will come to know about this properties file as we are just creating the file and not making any entry in code or web.xml???? -------------------- JasperReports library will look for this file. Regarding your license - was it hooked up by iReport? Was the report design compilable in iReport in the first place? Best regards, Vadim Chepuryaev
