Expression Value in Jasper Report: “Cannot cast from ByteArrayInputStream to String” error

I am trying to convert an encoded tag in an xml to image and then convert into PDF using Java and Jaspersoft Studio.
NOTE : When I am previewing in Jasper studio I am getting proper display image but getting the above error while running it using Java main method.
Motive of the code is to fetch the tag from xml and convert it to pdf with image.
I am using JasperReports 6.4.0. While previewing from Jaspersoft Studio image is getting displayed properly and jrxml file is getting compiled too. But while running using main method in Java, I am getting error.
Below is the jrxml file I am using.

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 addr;
public R(String name, String addr) {
super();
this.name = name;
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".

JasperReports renders empty pdf

I'm just doing a test, i want to print some static text yet it doesn't save pdf.

</jasperReport>
The code is:
public class PDF {
public void genereazaRaport() {
try {
InputStream input = new FileInputStream(new File("jrxml/test.jrxml"));
JasperDesign jasperDesign = JRXmlLoader.load(input);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
//Map<String, Object> parameters = new HashMap<String, Object>();
//parameters.put("Titlu Raport", "PDF JasperReport");
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, new JREmptyDataSource());
OutputStream out = new FileOutputStream(new File("raport/raport.pdf"));
JasperExportManager.exportReportToPdfStream(jasperPrint, out);
} catch (FileNotFoundException e) {
System.out.println("File not found");
} catch (JRException e) {
System.out.println("JRException");
}
}
public static void main(String[] args) {
new PDF().genereazaRaport();
}
}
And I get a blank page when it save in file. I think it's something that has to do with the datasource but i can't figure what.

Try this jrxml. It will work for you.

}

I think the issue here (which you have most probably discovered already as this question was aksed 7 months ago) is that you have placed the chart into the 'Detail' area. You will have the detail area repeated for each element returned (i.e. row of data in a query).
You should place the chart into the 'Title' area, or one of the other 'non-repeating' areas on a page.

Generating a pdf report using JasperRunManager

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();
}

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);
