PDF Accessibility | 'Title - Failed' Error

问题:

I am generating a PDF document from an XML using XSL template in Apache FOP API. My applications requires the PDF documents to be generated dynamically.

Despite of adding the title (code snippet below), I am getting 'Title - Failed' error when checked for Accessibility (full check) in Adobe Acrobat Pro 11.

回答1:

In Adobe Acrobat If I go to File --> Properties --> Initial View --> Select 'Document Title' in Show, the error is fixed. But I am not able to find anything to do the same thing programmatically, neither in XSL template nor in java code.

It looks like this issue has been fixed, probably in version 2.1. I just upgraded to FOP 2.2 after having this same issue while using version 1.1, and I'm pleased to report that everything works as expected now after opening a dynamically-generated PDF-UA file with Adobe Acrobat XI Pro.
