There were questions on that but not recently and technology must have gone ahead since then.
Requirements:
- generating pdf documents based on predefined template (I can use either pdf forms or xsl-fo)
- being able to fill textual data
- being able to fill graphical data (generated bar codes)
- being able to alter pdf template in production environment without patching (recompiling)
- generating pdf file to be saved in the database (as blob) and/or printed
- open source/free
The options assumed are iText, PDFBox, FOP, anything else? What are recommendations based on the requirements above?
