How can I export report to PDF/A-1a, PDF/A-1b?
Generating PDF/A in jasper-report, contains numerous pitfalls and is not supported in some versions of jasper-report. This is why I have decided to pass this Q
-
JasperReports Library 4.1.2.3 or higher is needed (with discontinued support in 6.0.0 see
NullPointerExceptionat the end).These steps are need to generate a PDF/A, they can be achieved both by java code or by setting jrxml
propertyto root tag (jasper-server support). I will show both but only one method is necessary.#Set PDF/A Conformance
java
configuration.setPdfaConformance(PdfaConformanceEnum.PDFA_1A); // or PdfaConformanceEnum.PDFA_1Bjrxml
#Set ICC Profile
to avoid
JRPdfaIccProfileNotFoundException: The ICC profile is not available to the JVMjava
configuration.setIccProfilePath("srgb.icc");jrxml
#Embed all font used in reports, using font-extensions
If you still have error
com.lowagie.text.pdf.PdfXConformanceException: All the fonts must be embedded. This one isn't: Helveticainclude a default style in the jrxml indicating
fontNamethat is included in font extension, example#Remove transparent objects and layers (Optional Content Groups) they are not allowed
to avoid
PdfXConformanceException: Transparency is not allowedIn example the chart element must be
Opaqueand to avoid transparency on the labels you can implement a JRChartCustomizerpublic class NoTransparencyCustomizer implements JRChartCustomizer{ @Override public void customize(JFreeChart chart, JRChart jrchart) { PiePlot plot = (PiePlot) chart.getPlot(); plot.setLabelShadowPaint(Color.GRAY); } }#Set Tagged and tag language (unnecessary for PDF/A-1b)
java
configuration.setTagged(true); configuration.setTagLanguage("en-us");jrxml
#Result
This is the result implementing the above, switching
fontNametoDejaVu Sansand using the bundledjasperreports-fonts.jaras font-extension. It has been validated successfully on pdf-tools for both PDF/A-1a and PDF/A-1bNo piece of the cake for me
XMP property is not synchronized with the document information
Validating file "reputation.pdf" for conformance level pdfa-1a dc:description/*[0] :: Missing language qualifier. dc:title/*[0] :: Missing language qualifier. The XMP property 'dc:title' is not synchronized with the document information entry 'Title'. The XMP property 'dc:description' is not synchronized with the document information entry 'Subject'.This error comes from using older jasper-reports library <6.2.0 when you set metadata title or subject in configuration.
configuration.setMetadataTitle("Title"); configuration.setMetadataSubject("Subject");The solution is to remove these or update jasper-reports to versione 6.2.0 or above see PDF/A_1A XMP Metadata validation fails if title and/or subject are set for more information
Discontinued support In jasper report version 6.0.0 a
NullPointerException at com.itextpdf.text.pdf.internal.PdfA1Checker.checkPdfObjectwas always thrown. This has been solved in 6.0.4 and above see Jasper report tracker.讨论(0)
