JasperReports library upgrade version 6.0.4 to 7.0.0

[Imz]

I am currently upgrading the JasperReports Library from version 6.0.4 to 7.0.0. My system is currently using the following JasperReports libraries:

- jasperreports-fonts-6.0.4.jar
- jasperreports-javaflow-6.0.4.jar

After upgrading these libraries, along with their dependencies and other JasperReports libraries:

- jasperreports-7.0.0.jar
- jasperreports-jdt-7.0.0.jar

The system throws an error when attempting to download the report (PDF). My system using Java Servlet.

 

System Error:

pw is to send text output to the client in a servlet or other Java-based web application.

eg:
 

import java.io.PrintWriter; 

public PrintWriter pw = null; 
pw = response.getWriter();

You need to use Jaspersoft Studio 7 to convert your reports (*.jrxml files) to the JasperReports 7 syntax.

Already convert my .jrxml files to JasperReports 7 syntax, but same error occurred.

I have try to add *.jar from Jasper 7 library and can download the pdf but cant view it. Now got this error:

Caused by: java.lang.NoClassDefFoundError: com/lowagie/text/pdf/FopGlyphProcessor

I have try to add itextpdf-5.5.13.4.jar, but same issue occurred.

[lucianc]

You need OpenPDF 1.3.32 on your application's classpath.

[Imz]

Thank you so much! I changed from iText to OpenPDF, and now the PDF can be viewed.

[Imz]

I got issue when want to download XLS format, now there is no issue when download PDF and XLSX. 

Error occurred -

Caused by: java.lang.ClassNotFoundException: net.sf.jasperreports.engine.export.JRXlsExporter

	... 128 more

Do you have any idea about this?

[lucianc]

You need jasperreports-excel-poi-7.0.0.jar

[Imz]

Yes already add jasperreports-excel-poi-7.0.0.jar, its worked for XLSX but not for XLS.

Also added jasperreports-excel-poi-7.0.0.jar, still not working.

[lucianc]

Have you also added the dependencies of jasperreports-excel-poi, such as POI 5.2.2?

[Imz]

Yes added, still error

[lucianc]

Please post the full exception stacktrace and the list of jars in your application.

[Imz]

It was a simple mistake on my part. I checked my program and noticed it was using import net.sf.jasperreports.engine.export.JRXlsExporter;. I changed it to import net.sf.jasperreports.poi.export.JRXlsExporter; and added SparseBitSet jar. It works now, and I can download .xls files. 

Thanks for your assistance!
