I am able to create a Master report using Jasper API. However stuck in designing a sub report using Jasper API and add it into Master report design.
Master Report JRXML
<band height="250" splitType="Stretch">
<subreport>
<reportElement isPrintRepeatedValues="false" x="0" y="0" width="550" height="233" isRemoveLineWhenBlank="true" backcolor="#000000"></reportElement>
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{time})]]></dataSourceExpression>
<subreportExpression><![CDATA["subreport.jasper"]]></subreportExpression>
</subreport>
</band>
Sub Report JRXML
<field name="count" class="java.lang.String"/>
<field name="timeStamp" class="java.lang.String"/>
<group name="ProductGroup">
<groupExpression><![CDATA[$F{count}]]></groupExpression>
<groupHeader>
<band height="250">
<timeSeriesChart>
<chart evaluationTime="Report">
<reportElement x="0" y="25" width="550" height="175"/>
<chartTitle/>
<chartSubtitle/>
<chartLegend/>
</chart>
<timeSeriesDataset timePeriod="Minute">
<dataset incrementType="None"/>
<timeSeries>
<seriesExpression><![CDATA["Count"]]></seriesExpression>
<timePeriodExpression><![CDATA[new Date(Long.valueOf($F{timeStamp})*1000)]]></timePeriodExpression>
<valueExpression><![CDATA[Integer.valueOf($F{count})]]></valueExpression>
</timeSeries>
</timeSeriesDataset>
<timeSeriesPlot isShowLines="true" isShowShapes="false">
<plot/>
<timeAxisFormat>
<axisFormat>
<labelFont/>
<tickLabelFont/>
</axisFormat>
</timeAxisFormat>
<valueAxisFormat>
<axisFormat>
<labelFont/>
<tickLabelFont/>
</axisFormat>
</valueAxisFormat>
</timeSeriesPlot>
</timeSeriesChart>
</band>
</groupHeader>
</group>
These Stand alone XML's getting compiled and will generate report.
However I want to create these using Jasper Report API. I have Just started. But stuck without any example available.
JRDesignSubreport jSubreport = new JRDesignSubreport(jasperDesign); jSubreport.setUsingCache(false); jSubreport.setRemoveLineWhenBlank(true); JRDesignExpression subReportDataSourceExpr = new JRDesignExpression();subReportDataSourceExpr.addResourceChunk("");//How to set List Data Source?JRDesignSubreportParameter subReportDataSource = new JRDesignSubreportParameter();subReportDataSource.setExpression(subReportDataSourceExpr);jSubreport.setDataSourceExpression(subReportDataSourceExpr); //How to Add <subreportExpression><![CDATA["subreport.jasper"]]></subreportExpression>

Ok. Issue is solved.
Here is the code block
band = new JRDesignBand(); band.setHeight(250); band.setSplitType(SplitTypeEnum.STRETCH);JRDesignSubreport jSubreport = new JRDesignSubreport(jasperDesign); jSubreport.setUsingCache(false); jSubreport.setRemoveLineWhenBlank(true); jSubreport.setPrintRepeatedValues(false);JRDesignExpression expression = new JRDesignExpression(); expression.setText("new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{time})"); jSubreport.setDataSourceExpression(expression);expression = new JRDesignExpression(); expression.setText("\"/path/to/sub.jasper\"");jSubreport.setExpression(expression); band.addElement(jSubreport);
How did you solve it?
How to do it?Can you please explain?
band = new JRDesignBand();
band.setHeight(250);
band.setSplitType(SplitTypeEnum.STRETCH);
JRDesignSubreport jSubreport = new JRDesignSubreport(jasperDesign);
jSubreport.setUsingCache(false);
jSubreport.setRemoveLineWhenBlank(true);
jSubreport.setPrintRepeatedValues(false);
JRDesignExpression expression = new JRDesignExpression();
expression.setText("new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource($F{time})");
jSubreport.setDataSourceExpression(expression);
expression = new JRDesignExpression();
expression.setText("\"/path/to/sub.jasper\"");
jSubreport.setExpression(expression);
band.addElement(jSubreport);
