Thanks ! net.sf.jasperreports.engine.util.JRProperties.setProperty(net.sf.jasperreports.engine.util.JRProperties.COMPILER_TEMP_DIR, sNomRepTrav)

Hello, when you execute JasperCompileManager.compileReportToFile(jasperDesign, sNomFicJasperAbs); Jasper generates a temporary file xyz.java in its own directory. Is it possible to specify the place for this xyz.java file to be generated ? (I don't have the permission to write in the bin directory) Post edited by: Peanut, at: 2006/11/02 09:30

OK, so the verifyDesign has nothing to do with XML checking. Thanks. So, as you said, I'm trying to catch exceptions on JRXmlLoader.load : Code:JasperDesign jasperDesign = new JasperDesign(); try { jasperDesign = JRXmlLoader.load(sNomFicJrxml); } catch (JRException e) { System.out.println( "[ERREUR] Problème lors du chargement du modèle JRXML : " + e.getMessage()); }That works but I'd like not all that exception buffer to be printed on the screen, but only my println (ie only the last line of this capture) : is it possible ? 5 oct. 2006 14:27:54 org.apache.commons.digester.Digester error SEVERE: Parse Error at line 19 column 29: L'élément racine du document "jasperReportKO" doit correspondre à la racine DOCTYPE "jasperReport". org.xml.sax.SAXParseException: L'élément racine du document "jasperReportKO" doit correspondre à la racine DOCTYPE "jasperReport". at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.error(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.dtd.XMLDTDValidator.rootElementSpecified(Unknown Source) at org.apache.xerces.impl.dtd.XMLDTDValidator.handleStartElement(Unknown Source) at org.apache.xerces.impl.dtd.XMLDTDValidator.startElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanStartElement(Unknown Source) at org.apache.xerces.impl.XMLDocumentScannerImpl$ContentDispatcher.scanRootElementHook(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl$FragmentContentDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XML11Configuration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.commons.digester.Digester.parse(Digester.java:1647) at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:238) at net.sf.jasperreports.engine.xml.JRXmlLoader.loadXML(JRXmlLoader.java:225) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:213) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:167) at net.sf.jasperreports.engine.xml.JRXmlLoader.load(JRXmlLoader.java:151) at jasper_compile_modele.main(jasper_compile_modele.java:133) [ERREUR] Problème lors du chargement du modèle JRXML : L'élément racine du document "jasperReportKO" doit correspondre à la racine DOCTYPE "jasperReport". I admit it's more a question about Java than about Jasper. :blush:

Hello, I've discovered the function JasperCompileManager.verifyDesign, and I wanted to use it in order to avoid my program crashing if the JRXML is not correct. But this function needs a JasperDesign for parameter: this means that you've already called one of the JRXmlLoader.load before... and your program would have certainly crashed in this function ! Indeed, I've tried to put different mistakes in my JRXML file, and each times my program crashes in JRXmlLoader.load, never reaching JasperCompileManager.verifyDesign. What do I miss ? :huh:

Here is a copy of my code working ! (not like so much on the net...)

Ah OK, that's not the way I was trying to use it. :blush: Thank you.

:side: Here is my code : Code:import java.io.*; // import des classes "Map" et "Hastable" pour l'envoi de paramètres à un rapport import java.util.Map; import java.util.Hashtable; import java.util.HashMap; // import du "moteur" de la librairie JasperReports import net.sf.jasperreports.engine.*; import net.sf.jasperreports.engine.export.JRCsvExporter; import net.sf.jasperreports.engine.design.JasperDesign; import net.sf.jasperreports.engine.xml.JRXmlLoader; import net.sf.jasperreports.engine.data.JRCsvDataSource; public class generatepdffromcsv { public static void main(String[] arguments) { String erreur = ""; Map params = new Hashtable(); try { System.out.println("Et c'est parti..."«»); // ????? params.put("animal", "animal"«»); params.put("mange", "mange"«»); params.put("couleur", "couleur"«»); // Chargement et compilation du rapport JasperDesign jasperDesign = JRXmlLoader.load("essai1.jrxml"«»); JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign); // déclaration de la source de données File sourceFile = new File("essai1.csv"«»); JRCsvDataSource source = new JRCsvDataSource(sourceFile); System.out.println("aaaa"«»); // ???? source.setFieldDelimiter(";"«»); // ???? source.setUseFirstRowAsHeader(TRUE); // export du rapport au format temporaire 'jasperPrint' JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,params,source); System.out.println("cccc"«»); // puis export du rapport au format PDF JasperExportManager exporter = new JasperExportManager(); exporter.exportReportToPdfFile(jasperPrint,"essai1.pdf"«»); System.out.println("That's all folks !"«»); } catch (Exception e) { System.out.println(e.getMessage()); } } } My CSV file : Code:[code]animal;mange;couleur; sanglier;glands;beige; vache;herbe;blanche; chat;souris;gris;(I've tried to replace ";" with "," since setFieldDelimiter doesn't compile, but it's the same. And the result : Code:[code]Et c'est parti... aaaa null :(

I've read the docs but they're really not clear, and a lot of things are deprecated. :unsure: I have a CSV file : Code:title1;title2;title3; dataa;datab;datac; datad;datae;dataf; ... and a jrxml file : Code:[code]... <field name="title1" class="java.lang.String"/> <field name="title2" class="java.lang.String"/> <field name="title3" class="java.lang.String"/> ... Is this OK ? : Code:[code]Map params = new Hashtable(); ... params.put("title1","title1"«»); params.put("title2","title2"«»); params.put("title3","title3"«»); ... JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,params,source); Thanks.

Hello, I'm a beginner with Jasper and even Java. To much for a day ! :P I'm trying since this morning to make all that stuff working, and I think I'm not so far... One thing I don't understand is the use of the second parameter of JasperFillManager.fillReport(). What kind of data do I have to put here please ?
