Apparently you need to pass a parameter map, for now I am just passing: <parametersMapExpression><![CDATA[$P{REPORT_PARAMETERS_MAP}]]></parametersMapExpression> This gets rid of the NPE at least.

Hi guys, I am using the WebServiceQuery to query a Rest service that returns an array, I output this on a report. This works fine. Now I want to embed this report as subreport on another report, but I suddenly get an NPE. I am using JasperSoft Studio 6.6.0. This is the frame that needs to display the subreport: <frame> <reportElement positionType="Float" mode="Transparent" x="0" y="0" width="560" height="215" isRemoveLineWhenBlank="true" forecolor="#9EC536" backcolor="#9EC536" uuid="be586fc9-f669-4c1f-a1d9-b6c0af9329fa"> <property name="com.jaspersoft.studio.unit.height" value="pixel"/> </reportElement> <subreport> <reportElement x="1" y="0" width="555" height="200" uuid="88025de9-5c1b-4451-83b0-3fa1f8f6cc9f"/> <subreportParameter name="verbKey"> <subreportParameterExpression><![CDATA[$P{verbKey}]]></subreportParameterExpression> </subreportParameter> <subreportParameter name="test"> <subreportParameterExpression><![CDATA["test"]]></subreportParameterExpression> </subreportParameter> <connectionExpression><![CDATA[$P{REPORT_CONNECTION}]]></connectionExpression> <subreportExpression><![CDATA["AttachmentSubreport.jasper"]]></subreportExpression> </subreport> </frame> I get the following error: net.sf.jasperreports.engine.JRException: net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: Error creating request: java.lang.NullPointerException at com.jaspersoft.studio.editor.preview.view.control.ReportController.fillReport(ReportController.java:536) at com.jaspersoft.studio.editor.preview.view.control.ReportController.access$17(ReportController.java:511) at com.jaspersoft.studio.editor.preview.view.control.ReportController$1.run(ReportController.java:429) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:56) Caused by: net.sf.jasperreports.engine.JRRuntimeException: net.sf.jasperreports.engine.JRException: Error creating request: java.lang.NullPointerException at net.sf.jasperreports.engine.fill.JRFillSubreport.prepare(JRFillSubreport.java:956) at net.sf.jasperreports.engine.fill.JRFillElementContainer.prepareElements(JRFillElementContainer.java:542) at net.sf.jasperreports.engine.fill.JRFillFrame.prepare(JRFillFrame.java:241) at net.sf.jasperreports.engine.fill.JRFillElementContainer.prepareElements(JRFillElementContainer.java:542) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:453) at net.sf.jasperreports.engine.fill.JRFillBand.fill(JRFillBand.java:428) at net.sf.jasperreports.engine.fill.JRFillBand.refill(JRFillBand.java:400) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillColumnBand(JRVerticalFiller.java:2642) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillDetail(JRVerticalFiller.java:813) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReportStart(JRVerticalFiller.java:264) at net.sf.jasperreports.engine.fill.JRVerticalFiller.fillReport(JRVerticalFiller.java:110) at net.sf.jasperreports.engine.fill.JRBaseFiller.fill(JRBaseFiller.java:615) at net.sf.jasperreports.engine.fill.BaseFillHandle$ReportFill.run(BaseFillHandle.java:135) at java.lang.Thread.run(Thread.java:748) Caused by: net.sf.jasperreports.engine.JRException: Error creating request: java.lang.NullPointerException 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 net.sf.jasperreports.engine.fill.BaseReportFiller.fill(BaseReportFiller.java:413) at net.sf.jasperreports.engine.fill.JRFillSubreport.fillSubreport(JRFillSubreport.java:814) at net.sf.jasperreports.engine.fill.JRSubreportRunnable.run(JRSubreportRunnable.java:61) at net.sf.jasperreports.engine.fill.AbstractThreadSubreportRunner.run(AbstractThreadSubreportRunner.java:221) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) ... 1 more Caused by: java.lang.NullPointerException at com.jaspersoft.webservice.data.util.WebServiceConnector.getRequestUrl(WebServiceConnector.java:199) at com.jaspersoft.webservice.data.util.WebServiceConnector.createGetRequest(WebServiceConnector.java:236) at com.jaspersoft.webservice.data.util.WebServiceConnector.createRequestForWs(WebServiceConnector.java:173) ... 14 more Any help is much appreciated, thanks!

Did you ever find out why? I got exactly the same problem. My report works fine in Jasper Studio 6.6.0. But on the server it runs the report and does not show the image.

Hello, I have an issue with hiding a frame when the IWSDataSource does not provide data. In our report, on the last page, we show our attachments. When there are attachments, this goes fine and the report creates the images on the last page. However, when there is no data coming from the IWSDataSource, the frame is still printed and therefor an empty page is added to the end of our PDF. I gave the frame a border with a colour so I could see that the frame is printed on the page that "appears" to be empty. I have tried several 'printWhenExpression' on the frame, but I can not seem to find/construct the correct one. Any help is appreciated, I have copied my jrxml code below. Thanks, Richard JR XML code:[/code]<frame> <reportElement positionType="Float" mode="Transparent" x="0" y="401" width="560" height="0" isRemoveLineWhenBlank="true" forecolor="#9EC536" backcolor="#9EC536" uuid="be586fc9-f669-4c1f-a1d9-b6c0af9329fa"> <property name="com.jaspersoft.studio.unit.height" value="pixel"/> <printWhenExpression><![CDATA[((com.jaspersoft.webservice.data.query.IWSDataSource)$P{REPORT_DATA_SOURCE}).clone("_attachments.*",$P{AttachmentsSubFieldsMap}) != null]]></printWhenExpression> </reportElement> <box> <pen lineWidth="1.0"/> </box> <componentElement> <reportElement positionType="Float" x="0" y="1" width="560" height="180" isRemoveLineWhenBlank="true" uuid="0b13fef0-f810-449b-82a5-da6376936dfd"> <property name="com.jaspersoft.studio.unit.x" value="pixel"/> <printWhenExpression><![CDATA[$P{AttachmentsSubFieldsMap} != null && !$P{AttachmentsSubFieldsMap}.isEmpty()]]></printWhenExpression> </reportElement> <jr:list xmlns:jr="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" printOrder="Horizontal"> <datasetRun subDataset="Attachments" uuid="29322791-2c92-4d6a-9624-d145428ecc41"> <dataSourceExpression><![CDATA[((com.jaspersoft.webservice.data.query.IWSDataSource)$P{REPORT_DATA_SOURCE}).clone("_attachments.*",$P{AttachmentsSubFieldsMap})]]></dataSourceExpression> </datasetRun> <jr:listContents height="180" width="280"> <image> <reportElement positionType="Float" x="0" y="0" width="275" height="180" isRemoveLineWhenBlank="true" backcolor="#9EC536" uuid="1f86c103-8861-40df-9ac1-fe76607915c4"/> <imageExpression><![CDATA[new java.io.ByteArrayInputStream(org.apache.commons.codec.binary.Base64.decodeBase64($F{data}.getBytes()))]]></imageExpression> </image> <textField> <reportElement x="0" y="0" width="275" height="180" forecolor="#FFFFFF" uuid="041dd200-9cc2-48a9-a624-b7aa021300ab"/> <textElement textAlignment="Right" verticalAlignment="Middle"> <font fontName="OpenSans"/> </textElement> <textFieldExpression><![CDATA[$F{data}.getBytes()]]></textFieldExpression> </textField> </jr:listContents> </jr:list> </componentElement> </frame>
