Hi, i'm new to Jasper Reports (and Java in general) and i'm VERY lost in the procedure of populating the report with data, not from a SQL query but from java variables. My report has only the 'title' and 'content' fields, both strings. The report contains two fields, "$F{title}" and "$F{content}". I'm trying to populate them with the following code: URL urlToFile = getClass().getResource("/jrSingleReport.jrxml"); InputStream reportXml = new FileInputStream(urlToFile.getFile()); JREmptyDataSource S = new JREmptyDataSource(); JasperDesign D = JRXmlLoader.load(reportXml); Map paramsReport = new HashMap(); paramsReport.put("title", "example title"); paramsReport.put("content", "dummy content"); JasperReport R = JasperCompileManager.compileReport(D); JasperPrint P = JasperFillManager.fillReport(R, paramsReport, S); JasperViewer V = new JasperViewer(P); V.setVisible(true); What i'm trying to get is a report with the words "example title" and "dummy content" and view it with the built-in viewer. But this code reports that it can't find "title" and "content" Please, can anyone give me some light in this issue? I'm having a very hard time trying to understand how JR works in this case.
