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[]]>
</queryString>
<field name="nom" class="java.lang.String">
<fieldDescription><![CDATA[name]]></fieldDescription>

<field name="dateDebut" class="java.lang.String">

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

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?
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".
I am creating JR report without using jrxml template. I need to know how can we set how image in the report title with Java code?
...
//Title
band = new JRDesignBand();
band.setHeight(50);
textField = new JRDesignTextField();
textField.setBlankWhenNull(true);
textField.setX(0);
textField.setY(10);
textField.setWidth(515);
textField.setHeight(30);
textField.setHorizontalAlignment(HorizontalAlignEnum.CENTER);
textField.setStyle(normalStyle);
textField.setFontSize(22);
expression = new JRDesignExpression();
expression.setValueClass(java.lang.String.class);
expression.setText("$P{ReportTitle}");
textField.setExpression(expression);
band.addElement(textField);
jasperDesign.setTitle(band);
Here instead of text field I need to add an image. What should I do?
You can use JRDesignImage class for setting image.
The sample:
public JasperDesign getJasperDesign() throws JRException {
JasperDesign jasperDesign = new JasperDesign();
jasperDesign.setName(DESIGN_NAME);
jasperDesign.setPageWidth(595);
jasperDesign.setPageHeight(842);
jasperDesign.setColumnWidth(515);
jasperDesign.setColumnSpacing(0);
jasperDesign.setLeftMargin(40);
jasperDesign.setRightMargin(40);
jasperDesign.setTopMargin(50);
jasperDesign.setBottomMargin(50);
JRDesignParameter parameter = new JRDesignParameter();
parameter.setName("ReportTitle");
parameter.setValueClass(java.lang.String.class);
jasperDesign.addParameter(parameter);
//Title band
JRDesignBand band = new JRDesignBand();
band.setHeight(250);
JRDesignTextField textField = new JRDesignTextField();
textField.setBlankWhenNull(true);
textField.setX(0);
textField.setY(10);
textField.setWidth(515);
textField.setHeight(30);
textField.setHorizontalAlignment(HorizontalAlignEnum.CENTER);
textField.setFontSize(22);
JRDesignExpression expression = new JRDesignExpression();
expression.setValueClass(java.lang.String.class);
expression.setText("$P{ReportTitle}");
textField.setExpression(expression);
band.addElement(textField);
// Image
String imgPath = "\"dukesign.jpg\"";
expression = new JRDesignExpression();
expression.setText(imgPath);
JRDesignImage image = new JRDesignImage(jasperDesign);
image.setX(45);
image.setY(55);
image.setWidth(130);
image.setHeight(104);
image.setScaleImage(ScaleImageEnum.FILL_FRAME);
image.setExpression(expression);
// Add image to Detail band
band.addElement(image);
jasperDesign.setTitle(band);
return jasperDesign;
}
The result will be (the generated pdf file):
I something like this with a List Component and a dataset

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:

By using iReport 4.6.0, I designed a report by inserting table component.
The jrxml file is as follows:
<?xml version="1.0" encoding="UTF-8"?>

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>
</datasetRun>
I want to generate a pdf report using ejbql ,but I dont know how to do that.
I have tried to do thye following but an error occure:
parameterMap.put(JRJpaQueryExecuterFactory.PARAMETER_JPA_ENTITY_MANAGER, entityManager);
parameterMap.put("priority", "3");
try
{
JasperFillManager.fillReportToFile("C:/Documents and Settings/MyDocuments/NetBeansProjects/JiraMap/src/java/Reports/Test.jasper", parameterMap);
JasperRunManager.runReportToPdfFile("C:/Documents and Settings/MyDocuments/NetBeansProjects/JiraMap/src/java/Reports/Test.pdf", parameterMap);
}
catch (JRException ex)
{
ex.printStackTrace();
}
Tehb error is:

I have use this code (I haven't use any parameter ) but always the report is empty:
JasperReport report = JasperCompileManager.compileReport("C:/Documents and Settings/My Documents/NetBeansProjects/JiraMap/src/java/Reports/Test.jrxml");
JasperPrint print = JasperFillManager.fillReport(report,null);
JasperExportManager.exportReportToPdfFile(print,"C:/Documents and Settings/My Documents/NetBeansProjects/JiraMap/src/java/Reports/Test.pdf");

This is part of the code I used for generating with JasperPrint; and sending the file back to a browser response. This using JDBC though, not EJBQL. But the JasperReports part of the code is the same.
FileResolver fileResolver = new FileResolver() {
#Override
public File resolveFile(String fileName) {
return new File(getServletContext().getRealPath("/") + fileName);
}
};
Map<String, Object> parameters = new HashMap<String, Object>();
parameters.put("REPORT_FILE_RESOLVER", fileResolver);
...... // blah blah
JasperPrint jrprint = JasperFillManager.fillReport(input, parameters, conn);
byte[] reportBytes;
jrprint.setName("MyFile." + fileFormat);
response.setContentType("APPLICATION/OCTET-STREAM");
String disHeader = "Attachment;Filename=\"MyFile.";
ServletOutputStream os = response.getOutputStream();
response.setHeader("Content-Disposition", disHeader);
reportBytes = JasperExportManager.exportReportToPdf(jrprint);
os.write(reportBytes);
You need to pass all the parameters needed as below:
JasperPrint jrprint = JasperFillManager.fillReport(input, parameters, connections);
