When I tried to generate a report by using JavaBean Data Source and displaying the bean's field values in the table, the PDF report is showing null values.
I have a simple bean (PersonBean) as follows:
public class PersonBean {
private String Field1;
private String Field2;
public String getField1() {
return Field1;
}
public void setField1(String field1) {
Field1 = field1;
}
public String getField2() {
return Field2;
}
public void setField2(String field2) {
Field2 = field2;
}
}
The Person class which populate and return the collection of bean is as follows:
import java.util.ArrayList;
import java.util.List;
public class Person {
public static java.util.List<PersonBean> getReportData() throws Exception {
List<PersonBean> personBeanList = null;
try {
personBeanList = new ArrayList<PersonBean>();
PersonBean personBean1 = new PersonBean();
personBean1.setField1("Hina");
personBean1.setField2("Sachdev");
personBeanList.add(personBean1);
PersonBean personBean2 = new PersonBean();
personBean2.setField1("Swathi");
personBean2.setField2("Singh");
personBeanList.add(personBean2);
} catch (Exception e) {
e.printStackTrace();
}
return personBeanList;
}
}
The PersonReport class which creates report is as follows:
import java.io.FileNotFoundException;
import java.util.*;
import net.sf.jasperreports.engine.*;
import net.sf.jasperreports.engine.data.JRBeanCollectionDataSource;
import net.sf.jasperreports.engine.design.JasperDesign;
import net.sf.jasperreports.engine.xml.JRXmlLoader;
import net.sf.jasperreports.view.JasperViewer;
public class PersonReport implements JRDataSource {
public static void main(String[] args) throws JRException, FileNotFoundException {
try {
Map<String, Object> params = new HashMap<String, Object>();
JasperDesign jasperDesign = JRXmlLoader.load("C:/Users/sachdevh/Desktop/reports/personReport.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, params,
new JRBeanCollectionDataSource(Person.getReportData()));
JasperExportManager.exportReportToPdfFile(jasperPrint, "./Util/bean.pdf");
JasperViewer.viewReport(jasperPrint);
} catch (Exception e) {
e.printStackTrace();
}
}
#Override
public Object getFieldValue(JRField arg0) throws JRException {
return null;
}
#Override
public boolean next() throws JRException {
return false;
}
}
By using iReport 4.6.0, I designed a report by inserting table component.
The jrxml file is as follows:

I think the datasource expression below
<dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JRBeanCollectionDataSource(Person.getReportData())]]></dataSourceExpression>
You can solve this issue in two steps:
Move table component to the Title band (now it lies in Column Header band) - to prevent occurring of net.sf.jasperreports.engine.JRRuntimeException: Infinite loop creating new page due to column header overflow exception in cases when datasource has a lot of elements;
Change the table's subDataset dataSourceExpression to value below, that is relevant to your Java code:
<datasetRun subDataset="New Dataset 1" uuid="f5f39e4f-4349-4e5d-9736-03f84a7a7617">
<dataSourceExpression><![CDATA[$P{REPORT_DATA_SOURCE}]]></dataSourceExpression>

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.
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?
I want to map my DataBean(TestModelA) to existing XML, but JasperReports gives me an exception. The problem is that I have custom field (TestModelB) and I have public getters and setters in that class, but jasper does not recognize them. How can i solve this problem?
TestModelA:
public class TestModelA {
private Long id;
private String label_key;
private TestModelB testModelB;
public TestModelA(Long id, String label_key, TestModelB testModelB) {
this.id = id;
this.label_key = label_key;
this.testModelB = testModelB;
}
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getLabel_key() {
return label_key;
}
public void setLabel_key(String label_key) {
this.label_key = label_key;
}
public TestModelB getTestModelB() {
return testModelB;
}
public void setTestModelB(TestModelB testModelB) {
this.testModelB = testModelB;
}
}
TestModelB:
public class TestModelB {
private Long owner;
public TestModelB(Long owner) { this.owner = owner; }
public Long getOwner() {
return owner;
}
public void setOwner(Long owner) {
this.owner = owner;
}
}

Your are passing TestModelA class as datasource you need either to create the method in this class or reference the method correctly from jasper report.
Solution 1 Create method in TestModelA
public Long getOwner() {
return getTestModelB().getOwner(); //Handle NullPointer?
}
Solution 2 Reference correctly in jrxml
<field name="testModelB" class="net.didorenko.model.TestModelB"/>

This question already has answers here:
How to fill report using JSON datasource without getting null values?
(3 answers)
Closed 6 years ago.
I'm beginner with JasperReports ( first try ) so,
I set up my netbeans, and my first try using data from database was successful. But now I just want to create my report from json data using Jasper Reports in Netbeans And I think it's not like getting data from Database.
By the way I tried to edit my xml file and add this :
<textField>
<reportElement x="0" y="31" width="555" height="20" uuid="9678a129-61e8-4034-ab8e-739ee5723c87"/>
<textElement textAlignment="Right">
<font size="12" isBold="true"/>
</textElement>
<textFieldExpression><![CDATA[$F{nom}]]></textFieldExpression>
</textField>
But it gives me null in report.
Here is what I did in java side :
Map parametersMap = new HashMap();
parametersMap.put("name", json.getString("Name"));
parametersMap.put("start", json.getString("Start"));
parametersMap.put("end", json.getString("end"));
String report = "C:\\My\\Path\\toReport\\report1.jrxml";
JasperReport Jasp = JasperCompileManager.compileReport(report);
JasperPrint JASP_PRINT = JasperFillManager.fillReport(Jasp,parametersMap);
JasperViewer.viewReport(JASP_PRINT);
UPDATED:
Here is my Java code
public void start(Future<Void> startFuture){
String fileJSON = "C:\\Users\\PathToMyFile\\data.txt";
String file = "/Test1/:name";
Router router = Router.router(vertx);
router.route(file).handler(routingContext -> {
HttpServerResponse response = routingContext.response();
response.setChunked(true);
routingContext.vertx().setTimer(1000, tid -> routingContext.response().end());
});
vertx.createHttpServer()
.requestHandler(router::accept)
.listen(8089, "localhost", res -> {
if (res.succeeded())
startFuture.complete();
else
startFuture.fail(res.cause());
});
vertx.fileSystem().readFile(fileJSON, (AsyncResult<Buffer> result) -> {
if (result.succeeded()) {
JsonObject json = result.result().toJsonObject();
try{
Map parametersMap = new HashMap();
parametersMap.put("name",json.getString("name"));
parametersMap.put("start",json.getString("start"));
parametersMap.put("end",json.getString("end"));
String report = "C:\\Users\\pathToMyPackage\\report1.jrxml";
JasperReport Jasp = JasperCompileManager.compileReport(report);
JasperPrint JASP_PRINT = JasperFillManager.fillReport(Jasp,parametersMap);
JasperViewer.viewReport(JASP_PRINT);
And for my JRXML file :
<property name="ireport.zoom" value="1.0"/>
<property name="ireport.x" value="0"/>
<property name="ireport.y" value="0"/>
<queryString language="json">
<![CDATA[]]>

And my JSON file :
{
"Name": "Test",
"Start": "16-06-2015",
"End":"16-06-2019"
}
You need to pass the data as a datasource, in json this is done by passing the stream through the parameter map (since you are using vertex, get the json in String format and then pass it as a stream).
Example
InputStream iostream = new ByteArrayInputStream(jsonString.getBytes(StandardCharsets.UTF_8));
parametersMap.put(JsonQueryExecuterFactory.JSON_INPUT_STREAM, iostream);
Then you can define the fields related to your json and json (xpath) query
Hi i'm new to jasper report.i'm using ireport for designing report.
I have created a simple report design, which have 2 fields name,addr.
public class R {
private String name;
private String addr;
public R(String name, String addr) {
super();
this.name = name;
this.addr = addr;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAddr() {
return addr;
}
public void setAddr(String addr) {
this.addr = addr;
}
}

Here i'm using array list as a data source.
When i click compile button on i report it shows error that
net.sf.jasperreports.engine.design.JRValidationException: Report design not valid : 1. Field not found : addr 2. Field not found : name
java code
public void runReport(String fileName, String outFileName) throws JRException
{
List<R> list = new ArrayList<R>();
Map parameters = new HashMap();
list.add(new R("a1" ,"a2"));
list.add(new R("b1" ,"b2"));
list.add(new R("c1" ,"c2"));
JasperPrint print = JasperFillManager.fillReport( fileName, parameters, new JRBeanCollectionDataSource(list));
JRExporter exporter = new JRPdfExporter();
exporter.setParameter(
JRExporterParameter.OUTPUT_FILE_NAME,outFileName);
exporter.setParameter(
JRExporterParameter.JASPER_PRINT, print);
JasperExportManager.exportReportToPdfFile(print, outFileName);
print = null;
exporter = null;
}
You should add to your jrxml field:
<field name="addr" class="java.lang.String">
<fieldDescription><![CDATA[addr]]></fieldDescription></field>
You can do it by clicking on "fields" and selecting "create field".
