Error embedding "Web Service Data Source" with "JasperReport Library" in a java application

Recommended Posts

I am trying to integrate "JasperReport Library" into a Java application.
I have designed a report with "JasperSoft Studio" + "Web Service Data Source".
From "JasperSoft Studio" the report is generated correctly from:

  • Open With -> JasperReport preview.

But when I try to launch it from my java application it throws an exception:

java.lang.RuntimeException: Can't generate report.        at org.gvsig.report.lib.impl.DefaultReport.generateReport(DefaultReport.java:114)        at org.gvsig.report.swing.impl.DefaultJReport.set(DefaultJReport.java:55)        ...        at java.awt.EventDispatchThread.run(EventDispatchThread.java:82)Caused by: net.sf.jasperreports.engine.JRException: Error creating request: net.sf.jasperreports.engine.JRException: The verb can't be null        at com.jaspersoft.webservice.data.util.WebServiceConnector.createRequestForWs(WebServiceConnector.java:187)        at com.jaspersoft.webservice.data.util.WebServiceConnector.callWS(WebServiceConnector.java:134)        at com.jaspersoft.webservice.data.query.WebServiceQueryExecuter.createDatasource(WebServiceQueryExecuter.java:168)        at com.jaspersoft.webservice.data.query.WebServiceQueryExecuter.createDatasource(WebServiceQueryExecuter.java:1)        at net.sf.jasperreports.engine.fill.JRFillDataset.createQueryDatasource(JRFillDataset.java:1257)        at net.sf.jasperreports.engine.fill.JRFillDataset.initDatasource(JRFillDataset.java:726)        at net.sf.jasperreports.engine.fill.BaseReportFiller.setParameters(BaseReportFiller.java:456)        at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:578)        at org.gvsig.report.lib.impl.DefaultReport.generateReport(DefaultReport.java:109)        ... 47 moreCaused by: net.sf.jasperreports.engine.JRException: The verb can't be null        at com.jaspersoft.webservice.data.util.WebServiceConnector.createRequestForWs(WebServiceConnector.java:178)        ... 55 more

The code I am using is the following:

    @Override    public Object generateReport(SimpleTaskStatus status) {       InputStream inputStream = null;        try {            inputStream = new FileInputStream(this.getFile());            Map parameters = new HashMap();            JasperDesign jasperDesign = JRXmlLoader.load(inputStream);                        JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);                        JasperReportsContext jasperReportsContext = DefaultJasperReportsContext.getInstance();            ReportFiller filler = JRFiller.createReportFiller(jasperReportsContext, jasperReport);            filler.addFillListener(new FillListener() {                @Override                public void pageGenerated(JasperPrint jasperPrint, int pageIndex) {                    LOG.info("Pagina generada "+pageIndex);                }                @Override                public void pageUpdated(JasperPrint jasperPrint, int pageIndex) {                    LOG.info("Pagina actualizada "+pageIndex);                }            });            JasperPrint jasperPrint = filler.fill(parameters);  //<<-- line 109: here crash            return jasperPrint;        } catch (Exception ex) {            throw new RuntimeException("Can't generate report.", ex);                    } finally {            try {                if( inputStream!=null ) {                    inputStream.close();                }            } catch (IOException ex) {            }        }    }[/code]

The jars that I am including are those that correspond with the dependencies of:

  •  jasperreports-6.6.0.jar

But the ones that I have supposed that "Web Service Data Source" requires:

  • WebServiceDataAdapter.jar
  • GoogleAuthenticator.jar
  • ElasticSearchConnector.jar

Do I need to configure something to use "Web Service Data Source" from my application?

Any clue that you can give me I would appreciate it.

a greeting
