How to fill JasperReports report using spring data Jpa native query?

I am trying to fill the jasper report using customized sql qyery but I am getting this error:-

I'm using jdbc adapter and I am trying to fill jasper report using this query in my repository
SELECT vehicle_class, COUNT(*)/SUM(1e0/speed) AS speed FROM violations GROUP BY vehicle_class
I removed field description from report but its still not worth it.

How to create nested table like jasper report?

I have been trying to create a jasper report which should look like the following image:
For my sample report, Out-1 and Out-2 are rows for the outer table and asd, asds, adasd are rows for the inner table.
I am trying to achieve it using nested tables. But the table takes the field and I can not assign field to the inner-table.
I am creating jasper reports in Java code rather than using SQL connection to the table for some reason.

You are missing the concept of the detail band, the detail will iterate on the datasource you pass to report
JasperFillManager.fillReport(jasperReport, parameters, jrEmptyDataSource)
That's an empty datasource!, it will not iterate at all.
Instead, pass
JRBeanCollectionDataSource outerTableItems = new JRBeanCollectionDataSource(outerTableList);
To the report, define the fields of OuterTable in your main report (not a subDatasource) including nestedTable
<field name="nestedTable" class="net.sf.jasperreports.engine.data.JRBeanCollectionDataSource"/>
Then
In detail band you put textFields related to first level "Out-1" and "Out-2" in your example.
Bellow you add the jr:table component taking the datasource from the bean
<datasetRun subDataset="New Dataset 1" uuid="17a10558-3a43-47c2-809d-6362924e5015">
<dataSourceExpression><![CDATA[$F{nestedTable}]]></dataSourceExpression>
</datasetRun>
In general within the bean I would not have JRBeanCollectionDatasource but instead store the data in a normal List<>, the reason is that a JRDatasource is consumable you can only use it once, see this to understand better How to use same JRBeanCollectionDataSource on multiple sub reports?

Working with multiple data sources in jaspersoft studio

After being able to add custom data source from java bean to a report according to Add custom data source to Jaspersoft Studio , I get to the second point of my reporting with jasper.
I have a main report which uses a data base as its data source. Then I add a bean.xml data source to the report and add a table to the main report which uses this bean.xml data source to get java beans.
My goal is to get a field value from the main report and manipulate
its value, then fill the beans with these values and at last fill the
table with the beans.
To do this I have written 3 classes which I use as Scriptlet in the table data set:
This is an illustration of what I need to do:
The problem is in FillTable class, when I us String kNFormelGG = (String) this.getParameterValue("gg"); the created bean.xml fails the test connection with java.lang.reflect.InvocationTargetException
Caused by: java.lang.NullPointerException
at net.sf.jasperreports.engine.JRAbstractScriptlet.getParameterValue(JRAbstractScriptlet.java:95)
at net.sf.jasperreports.engine.JRAbstractScriptlet.getParameterValue(JRAbstractScriptlet.java:86)
at org.iqtig.reporting.dataSource.bean.dataSourceXML.FillTable.fillTable(FillTable.java:45)
at org.iqtig.reporting.dataSource.bean.dataSourceXML.JRDataSourceFactory.createCollection(JRDataSourceFactory.java:27)
... 34 more
If I assign a fix value like String kNFormelGG ="Test me" the bean connection encounters no error and after assigning bean.xml as the value for Default Data Adapter in Dataset1 it fills the table with static values.
How can get the data from a parameter or a value dynamically from the main report data source and use it in beans?
I have this assumption that at the time of calling the static factory class from my adapter, the fields are still empty. Maybe I am wrong but I do not find any other declaration for this problem.

My goal is to get a field value from the main report and manipulate
its value, then fill the beans with these values and at last fill the
table with the beans.
I will ignore all your scriplets and other code and show you the simplest way to create a dynamic datasource for another component using a current field, variable or parameter value.
As example we will have these String values in field1 (row1, row2)
Test1_1.23:Test2_4.32:Test3_1.08
Test1_2.12:Test2_5.12:Test3_2.13
We want to split on : and create rows (List of beans), then split on _ to create columns (properties on bean) and display this in a jr:table component.
java code (or Bean)
public class TableCellsBean {
private String name;
private double value;
public TableCellsBean(String name,double value){
this.name = name;
this.value = value;
}
public static JRBeanCollectionDataSource getDatasource(String fieldValue){
List<TableCellsBean> retList = new ArrayList<>();
String[] values = fieldValue.split(":");
for (String v : values) {
String[] sp = v.split("_");
retList.add(new TableCellsBean(sp[0], Double.parseDouble(sp[1])));
}
return new JRBeanCollectionDataSource(retList);
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public double getValue() {
return value;
}
public void setValue(double value) {
this.value = value;
}
}
As you can see already inside this bean class I have added a static method that returns a JRBeanCollectionDataSource depending on value passed as parameter.
Basically you pass a fieldValue to this method, it does some logic, creates the TableCellBean, adds them to list and return a JRBeanCollectionDataSource
Note: The method does not need to be static nor inside this class, furthermore exception handling is not considered.
Report - the jrxml
In example we will have field1 containing Test1_1.23:Test2_4.32:Test3_1.08 on row 1 and Test1_2.12:Test2_5.12:Test3_2.13 on row 2.
We define a subdataset that represents out TableCellsBean
<subDataset name="table_dataset" uuid="4dc1b0fb-2588-4f98-8c8d-f0afefbb2fd1">
<field name="name" class="java.lang.String"/>
<field name="value" class="java.lang.Double"/>
</subDataset>
as datasource we call our static method passing the field1 content in current row.
<dataSourceExpression><![CDATA[my.package.TableCellsBean.getDatasource($F{field1})]]></dataSourceExpression>

Test the example
Adding main method to export to pdf
public static void main(String[] args) throws JRException {
//Compile report
JasperReport report = JasperCompileManager.compileReport("myJasperReport.jrxml");
//Setting up some arbitrary data to test the auto creation of datasource
List<String> someData = new ArrayList<>();
someData.add("Test1_1.23:Test2_4.32:Test3_1.08");
someData.add("Test1_2.12:Test2_5.12:Test3_2.13");
//Fill report
JasperPrint jasperPrint = JasperFillManager.fillReport(report, new HashMap<>(),new JRBeanCollectionDataSource(someData));
//Export to pdf
JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("myJasperReport.pdf"));
SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
exporter.setConfiguration(configuration);
exporter.exportReport();
}
Output
Conclusion
The simplest way to provide components with custom datasource depending on running reports values (fields, variables, parameter), is to create a method that generates the datasource and call this in dataSourceExpression

JRBeanCollectionDataSource: How to show data from the java.util.List from JavaBean?

My JavaBean contains the java.util.List.
Userinfo {
private String username;
private String password;
List<Address> listAddress;
}
How to show the data of this List in the Detail band?

Here is the working sample.
The key points of this sample:
using of the _THIS expression;
using List (jr:list) component in Detail band
The snippet of code for generating report:
public static void testBuildPdf() {
try {
Map<String, Object> params = new HashMap<String, Object>();
JasperReport jasperReport = JasperCompileManager.compileReport(reportSource);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params, getDataSource());
JasperExportManager.exportReportToPdfFile(jasperPrint, outputFileName);
} catch (Exception e) {
e.printStackTrace();
}
}
private static JRDataSource getDataSource() {
Collection<BeanWithList> coll = new ArrayList<BeanWithList>();
coll.add(new BeanWithList(Arrays.asList("London", "Paris"), 1));
coll.add(new BeanWithList(Arrays.asList("London", "Madrid", "Moscow"), 2));
coll.add(new BeanWithList(Arrays.asList("Rome"), 3));
return new JRBeanCollectionDataSource(coll);
}
The JavaBean code:
public class BeanWithList {
// The member's name can be any. The JR engine is using public getter for extracting field's value
private List<String> cities;
private Integer id;
public BeanWithList(List<String> cities, Integer id) {
this.cities = cities;
this.id = id;
}
// getter should be public
public List<String> getCities() {
return this.cities;
}
public Integer getId() {
return this.id;
}
}
