I am trying to generate a PDF file using JasperReports, however, regardless of how I try it, it's giving me a NullPointerException.
https://community.jaspersoft.com/questions/520803/getting-null-pointer-exception-fillreport
Tried looking there, and changed the jasper properties file, but it didn't do anything and i'm still getting the same error.
Tried absolute paths, relative paths, getting resource as stream, nothing
This is the code i'm using to generate the report
public String generateInvoiceFor (Reservation reservation) throws JRException {
JasperReport jasperReport = JasperCompileManager.compileReport("I:\\anoranzaHopefullyFinal\\src\\main\\resources\\jasper\\FacturaFinalFinal.jrxml");
List<Reservation> reservations = reservationService.getAll();
JRBeanCollectionDataSource jrBeanCollectionDataSource = new JRBeanCollectionDataSource(reservations);
Map<String,Object> parameters = new HashMap<>();
parameters.put("Idparam", reservation.getId());
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, jrBeanCollectionDataSource);
JasperExportManager.exportReportToPdfFile(jasperPrint, "jasper/jasperOutput/Factura.pdf");
return "Report successfully generated #path= jasper/jasperOutput/";
}
Check your datasource and jasperPrint. If there is no problem try this.
JRPdfExporter exporter = new JRPdfExporter();
exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
exporter.setExporterOutput(
new SimpleOutputStreamExporterOutput("PDF NAME IS HERE.pdf"));
SimplePdfReportConfiguration reportConfig
= new SimplePdfReportConfiguration();
reportConfig.setSizePageToContent(true);
reportConfig.setForceLineBreakPolicy(false);
SimplePdfExporterConfiguration exportConfig
= new SimplePdfExporterConfiguration();
exportConfig.setMetadataAuthor("Auth name is here");
exportConfig.setEncrypted(true);
exportConfig.setAllowedPermissionsHint("PRINTING");
exporter.setConfiguration(reportConfig);
exporter.setConfiguration(exportConfig);
exporter.exportReport();

I am new to Spring Boot. I have this emailprop.properties in src/main/resource:
//your private key
mail.smtp.dkim.privatekey=classpath:/emailproperties/private.key.der
But I am getting the error as
classpath:\email properties\private.key.der (The filename, directory
name, or volume label syntax is incorrect)
How do I properly load this file?
Update-1
my java code is
dkimSigner = new DKIMSigner(emailProps.getProperty("mail.smtp.dkim.signingdomain"), emailProps.getProperty("mail.smtp.dkim.selector"),
emailProps.getProperty("mail.smtp.dkim.privatekey"));
its working as "D:\\WorkShop\\MyDemoProj\\EmailService\\src\\main\\resources\\private.key.der"Instead of emailProps.getProperty("mail.smtp.dkim.privatekey")
Update-2
i have tried java code is
String data = "";
ClassPathResource cpr = new ClassPathResource("private.key.der");
try {
byte[] bdata = FileCopyUtils.copyToByteArray(cpr.getInputStream());
data = new String(bdata, StandardCharsets.UTF_8);
} catch (IOException e) {
e.printStackTrace();
}
dkimSigner = new DKIMSigner(emailProps.getProperty("mail.smtp.dkim.signingdomain"), emailProps.getProperty("mail.smtp.dkim.selector"),data);
Error is : java.io.FileNotFoundException: class path resource [classpath:private.key.der] cannot be resolved to URL because it does not exist
Tried Code is :
ClassPathResource resource = new ClassPathResource(emailProps.getProperty("mail.smtp.dkim.privatekey"));
File file = resource.getFile();
String absolutePath = file.getAbsolutePath();
Still same error..
please update the answer..
If you want to load this file runtime then you need to use ResourceLoader please have a look here for the documentation - section 8.4.
Resource resource = resourceLoader.getResource("classpath:/emailproperties/private.key.der");
Now if you want to keep this exact path in properties file you can keep it there and then load it in your Autowired constructor/field like that:
#Value("${mail.smtp.dkim.privatekey}") String pathToPrivateKey
and then pass this to the resource loader.
Full example you can find here. I don't want to copy paste it.
If your file is located here:
"D:\\WorkShop\\MyDemoProj\\EmailService\\src\\main\\resources\\private.key.der"
then it should be:
mail.smtp.dkim.privatekey=classpath:private.key.der
EDIT:
I see now, you are using DKIMSigner, which expects file-path string,
Try changing your code like this:
ClassPathResource resource = new ClassPathResource(emailProps.getProperty("mail.smtp.dkim.privatekey"));
File file = resource.getFile();
String absolutePath = file.getAbsolutePath();
dkimSigner = new DKIMSigner(emailProps.getProperty("mail.smtp.dkim.signingdomain"), emailProps.getProperty("mail.smtp.dkim.selector"),absolutePath
);
I am trying to replace an existing Community file using the following java
Map<String, String> paramsMap = new HashMap<String, String>();
paramsMap.put("createVersion", "false");
fileEntry = fileService.updateCommunityFile(fis, fileUuid, fileName, communityLibraryId, paramsMap);
But it is returning a HTTP 411:Length required error.
I am using the latest build (1.1.5.20150520-1200.jar)
Does anyone have a suggestion as to what i am missing?
I tried recreating the issue but I am able to upload New version of Community file correctly with and without version, using the updateCommunityFile API. I do not get any Length related error. This is the snippet I am using :
java.io.File file = new java.io.File("C://TestUploadCommunity.txt");
FileInputStream fis = null;
try {
fis = new FileInputStream(file);
} catch (Exception e) {
//TODO
}
fileEntry = fileService.updateCommunityFile(fis, fileEntry.getFileId(), fileEntry.getLabel(), communityLibraryId, params);
Can you share more details on your sample, what exactly is your fis?
I have tried this on 2 environments and I do not see any issue.
Also, from the entry you have pasted,
"Request to url apps.na.collabserv.com/files/basic/api/library... /document/... /entry?content-length=6600&createVersion=false returned an error response 411:Length Required HTTP/1.1 411"
It seems that somehow an incorrect content-length is passed for your request.
Can you share the sample that you are using?
I need to produce i18n reports with existing code using JasperReports (4.7.1 originally but same problem with 5.6.1).
I did the following:
Report name is: x_report.jrxml
Added attribute resourceBundle="x_report" to the jasperReport tag in the jrxml file
Replaced text with $R{} tags in jrxml file
Built file
Added JRParameter.REPORT_LOCALE and JRParameter.REPORT_RESOURCE_BUNDLE to the parameters to pass to the JasperFillManager:
File reportFile = new File(getClass().getResource("/reports").getFile(), report.getReportFileName());
Map<String, Object> fillParams = (Map<String, Object>) report.getFillParameters();
java.util.Locale locale = new java.util.Locale("it");
fillParams.put(JRParameter.REPORT_LOCALE, locale);
String resBundleName = ...
ResourceBundle resBundle = ResourceBundle.getBundle(resBundleName, locale);
fillParams.put(JRParameter.REPORT_RESOURCE_BUNDLE, resBundle);
...
The JasperFillManager getting the params (with locale and resource bundle) and the report path:
BeanReport report = (BeanReport) this.report;
Collection<?> beans = report.getBeans();
JRBeanCollectionDataSource ds = new JRBeanCollectionDataSource(beans);
JasperPrint print = JasperFillManager.fillReport(reportFile.getPath(), fillParams, ds);
...
if (httpSession != null) {
httpSession.setAttribute(ImageServlet.DEFAULT_JASPER_PRINT_SESSION_ATTRIBUTE, print);
exporter.setParameter(JRHtmlExporterParameter.IMAGES_URI, "ReportImage?image=");
}
exporter is a JRExporter:
exporter.setParameter(JRExporterParameter.JASPER_PRINT, print);
exporter.setParameter(JRExporterParameter.CHARACTER_ENCODING, "UTF-8");
exporter.exportReport();
The resource bundle is found but my generated report still has the $R{} tags instead of the localized text.
What could be missing?
Thank you for your help!
I'm not sure if you are using JasperReports Server or not, but if you are what worked for me was to drop my properties bundle files into the ../jasperserver-pro/WEB-INF/classes folder.
I have an application built in GWT and Spring. I am trying to generate Jasper Reports on the server side. However when I execute the functionality, it hangs/stops at jasperDesign = JRXmlLoader.load(file_name); and does not respond or throw an exception. This means that my RPC call that triggers the report generation function does not return a response either (so the application hangs). However when I run the function in a normal java application it generates a report without any problem. What could be the issue? I am using JasperReports version 5.6.0. My java function:
public StandardServerResponse printReport(List<Object> items) {
StandardServerResponse response = new StandardServerResponse();
String file_name = null;
Map<String, Object> parameters;
JasperDesign jasperDesign;
JasperReport jasperReport;
JasperPrint jasperPrint;
try {
for (Object obj: items) {
parameters = new HashMap<String, Object>();
parameters.put("id_in", obj.getId());
file_name = "G:\\myreport.jrxml";
jasperDesign = JRXmlLoader.load(file_name); //application stops here
jasperReport = JasperCompileManager.compileReport(jasperDesign);
jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, dataSource.getConnection());
JasperExportManager.exportReportToPdfFile(jasperPrint, "G:\\report.pdf");
}
response.setSuccess(true);
} catch (Exception ex) {
ex.printStackTrace();
response.setSuccess(false);
}
return response;
}
I finally solved my problem after many long days of debugging :-).
I had these two jars in my WEB-INF/lib folder.
jasperreports-functions-5.6.0-SNAPSHOT.jar
jasperreports-fonts-5.6.0.jar
I removed them and the app worked. I still don't understand why they would cause a problem though.
I also changed my code to work with a .jasper extension and directly called JasperRunManager.runReportToPdfFile(file_name, "S:\\output_report.pdf", parameters, connection);
Thanks a lot Darshan Lila for trying, I really appreciate. Hope this helps someone.
Is it possible with jasper Reports to load a ResourceBundle (for i18n) at runtime?
I want to create a report from a jrxml file (for example c:\reports\report.jrxml)
with my labels in the properties file located at (c:\messages\report.properties).
I only found example where the property file is in the classloader.
Thanks
John Ferguson's blog mentions that the trick is to override the REPORT_RESOURCE_BUNDLE parameter with a custom ResourceBundle instance.
// Compiling the report is not a necessary step; prefer using .jasper files
// that have been pre-compiled to avoid this compilation step.
//
JasperDesign jasperDesign = JasperManager.loadXmlDesign("Report.jrxml");
JasperReport jasperReport = JasperManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("REPORT_LOCALE",LocaleManager.currentLocale());
parameters.put("REPORT_RESOURCE_BUNDLE",resourceBundle);
Connection conn = DBConnectionFactory.getConnection();
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport,
parameters,
conn);
The resourceBundle can come from anywhere. For example:
try(FileInputStream fis = new FileInputStream("/tmp/report.properties")) {
ResourceBundle resourceBundle = new PropertyResourceBundle(fis);
// Pass resourceBundle into the report, as shown above.
}
loading bundle from resources package:
ResourceBundle bundle=ResourceBundle.getBundle("/reports/bundles/bundle",Locale.CANADA_FRENCH);
filling report::
params.put("REPORT_RESOURCE_BUNDLE", bundle);
JasperPrint jasPrint = JasperFillManager.fillReport(reportStream, params, data);
