Hello, I am trying to use iText for adding page numbers to the already existed PDF using PDFStamper class. I have problem. PDFs, which I create using Apache FOP 0.95, cause Exception as shown below, although they look OK in Adobe Acrobat Reader 8.1.2. I guess, that this is problem of missing or wrong encoding somewhere (but where?). Attached to this e-mail are: FO source, resulted PDF, Java code for iText. I am using Sun Java SE 1.6.0_10 on MS Windows 2000. Please, can You point me, where I am making miskate?
Thank You. Stepan
