Thanks for your interest in our products.
Aspose.Pdf for Java is a component which provides the feature to create PDF files from scratch. However we have a separate component named Aspose.Pdf.Kit for Java which supports the feature to manipulate existing PDF document. I am afraid currently Aspose.Pdf.Kit for Java does not support the feature to convert PDF file into PDF/A format. For the sake of implementation, we already have logged this requirement as PDFKITJAVA-28640. The development team is working on implementing this feature and as soon as we have some have significant progress, we will let you know.
We are using Java 1.6 - why would we need to use Retrotranslater? Looking at the web page it is all about Java 5.0 support.
Aspose.Pdf for Java and Aspose.Pdf.Kit for Java are supported over JDK 1.5, 1.6 and 1.7. Please continue using our products and in case you encounter any problem, please feel free to contact.
The download link for JAI still points to http://java.sun.com/
… where Sun has been bought by Oracle some time ago. Why would we need JAI?
JAI is required when trying to convert TIFF image to PDF or during the conversion of PDF file into TIFF image using Aspose.Pdf.Kit for Java.
We are sorry for your inconvenience.
